Fumikage Tokoyami

Fumikage Tokoyami (常闇踏陰) is a student at U.A. training to become a Hero.

Appearance
Fumikage is a relatively short person with a bird-shaped head, spiky "hair", red eyes, a striped red choker, a short beak and human teeth. Despite those traits, the rest of his body is that of a regular human shape.

His Hero Costume consists mostly of a dark cloak and clothes that cover his whole body from the neck down.

Personality
Fumikage has a reserved, serious and focused personality. Though he does not talk very much, he has been shown directly ignoring questions or requests that seem in some way pointless (like Tenya asking him to not sit on the desk) while he talks to other people as some sort of ongoing joke. When Fumikage teams up with others, he becomes more sociable, helping his teammates out, reassuring his trust in them and thanking them for their effort.

He appears to be fond of darkness and other related concepts, sometimes coming off as a slightly dramatic. Despite this, he is also shown to be embarrassed about his interests to a certain degree, refusing to let his classmates see his gloomy room. Fumikage also seems to have a certain level of belief in the concept of fate and destiny.

Fumikage also seems to be aware of his own limits and understands when it's time to back down, surrendering when Katsuki Bakugo forced him into a difficult position to fight back. He takes any advice he gets seriously, and uses it to try and improve on his Quirk and abilities.

Unforeseen Simulation Joint Arc
Fumikage is warped by Kurogiri to the Downpour Storm Zone along with Koji. Their battle is not seen, but they apparently defeat the villains that were in the area and afterwards, he is seen with his class after the battle with the League of Villains is over.

Sports Festival Arc
Two days after the attack on the U.S.J., Fumikage and his classmates return to school discuss the attack. After Mister Aizawa returns to class, the class gets lectured about the importance of the upcoming U.A. Sports Festival. Fumikage is amongst those who are freaked out when Ochaco Uraraka gets overly excited and demands the class chant that they will do their best in the festival.

At the end of the day, Class 1-A's exit gets blocked by a crowd of students from other classes. Katsuki confronts and insults the crowd, making enemies out of everyone else before leaving. Eijiro tries to get Katsuki to defend the class, but he replies that the crowd of students are irrelevant and it's only important that he defeats them. Fumikage agrees with Katsuki's statement.

For the next two weeks before the festival, Fumikage trains at the Replica City District. He uses stadium lights to improve Dark Shadow's endurance. When the day of the U.A. Sports Festival arrives, Fumikage changes into his P.E. clothes and prepares with his class in their designated waiting room. Like the rest of his peers, Fumikage takes notice when Shoto Todoroki challenges Izuku Midoriya.

Chief referee of the Sports Festival: Midnight announces the preliminaries will be an Obstacle Race four kilometers around the stadium, which immediately begins after the rules are explained. Fumikage eventually reaches the first obstacle: a blockade of Villain-bots from the entrance exam, including several giant Zero-Point Villains.

Katsuki is one of the first to clear the obstacle by rocketing over the giant robots using his Quirk. Fumikage and Hanta Sero follow close behind using Quirks of their own. Fumikage crosses the finish line in seventh place, qualifying him to participate in the Cavalry Battle.

Izuku Midoriya convinces Fumikage to join his team for the Cavalry Battle. The former explains that Fumikage's role will only be to defend the team with his Quirk. Impressed with Izuku's strategy, Fumikage reveals his Quirks weakness and comments that Izuku has chosen the perfect role for him since his Dark Shadow's offensive ability is lessened in the sunlight.

The second round of the festival begins, and along with Ochaco Uraraka and Mei Hatsume, it's up to Fumikage to help Izuku protect their ten million points.

As soon as the round begins, Team Tetsutetsu attacks and traps Team Midoriya using Juzo Honenuki's Quirk. Thanks to gadgets Mei provided the team with, Fumikage and company are able to escape by flying through the air. Kyoka Jiro tries to attack their blind spot, but Dark Shadow repels it. Izuku comments on Fumikage's powerful Quirk and how perfectly it suits the team just before they land safely using Ochaco's power.

They are given few seconds of safety, as Team Mineta immobilizes them momentarily using one of Minoru's spheres. Then Team Tetsutetsu joins the fray and charges for Fumikage's party.

Outnumbered, Fumikage reminds Izuku that it is unwise to get trapped between two teams. Izuku breaks one of the hover soles used to maneuver through the air in order to escape and Katsuki confronts them in mid-air. He nearly blasts Izuku, but Fumikage is able to block the explosion using Dark Shadow. They are forced to land, and are almost instantly confronted by Team Todoroki.

Fumikage believed this confrontation wouldn't happen until later in the contest and comments that Shoto must have it out for Izuku. Various teams close in on them, but Team Todoroki's Denki Kaminari shocks them all using his Indiscriminate Shock technique. Fumikage is able to defend the team from the electricity using Dark Shadow, but Team Todoroki continues to pursue them. Dark Shadow tries to strike Shoto, but Momo Yaoyorozu creates a strong enough shield to block it's attack. Izuku comments that Momo's Quirk is too powerful, but Fumikage replies that Denki is the one to fear and if there were any more sunlight Dark Shadow could have been destroyed by his attack.

Izuku invokes a strategy that keeps Team Todoroki at bay for the latter half of the games, but their points are ultimately stolen after Tenya uses his Recipro Burst technique. Fumikage stares at Team Todoroki, alarmed by Tenya's lightning speed, and suggests to Izuku that their team try for other points. Izuku refuses and with encouragement from Ochaco, they decide to charge at Team Todoroki to reclaim their points. Izuku is able to grab one of their headbands, but it turns out not to be the one worth ten million points.

Without enough points to move onto the next round, Team Midoriya makes one final attempt. Fumikage sends Dark Shadow to attack, but Denki repels him with electricity. Katsuki arrives on the scene, but time runs out just as everyone is about to clash.

Izuku tries to apologize for the loss, but Fumikage interjects. He reveals that he tried for the ten million points, but was unable to grab it. Instead, thanks to Izuku's attack, Dark Shadow was able to steal the headband around Shoto's head. The headband is worth is enough to place Team Midoriya in fourth, allowing them to advance to the finals.

Midnight announces the finals will be a One on One Fighting Tournament and everyone draws lots to see who they will face in the first bracket. Fumikage matches up with Momo, and he promises her to give it his all. Before the tournament begins, participants are given the option to participate in recreational games. Fumikage refuses and uses the opportunity to recharge Dark Shadow while resting high on a tree branch.

Fumikage faces his opponent, Momo, in his first round match. Fumikage manages to defeat Momo by striking first and making sure she was unable to use any of the creations she prepared, making him the winner and allowing him to move on to the next round.

Fumikage sits next to Ochaco and Tenya before the match between Izuku and Shoto begins. As Ochaco sits down, Fumikage comments that instead of lamenting over what can't be changed, one should rather take inspiration from their battles, to which Ochaco agrees with. Fumikage watches the battle between Izuku and Shoto.

Fumikage faces his opponent, Mina, in his second round match. Fumikage defeats Mina and moves on to the third round (the semi-finals).

Fumikage faces his opponent, Katsuki, in his third round match. Unlike his previous matches, Fumikage is at a major disadvantage and is forced to go completely on the defensive due to the light from Katsuki's Explosions weakening Dark Shadow and that Dark Shadow hasn't fully replenished its strength. Even worse, Katsuki's fierce fighting style prevents Fumikage from countering. Despite this, Fumikage does manage to keep Katsuki at bay. Katsuki attacks Fumikage's Dark Shadow with multiple Explosions. Fumikage notes that he underestimated Katsuki and that Dark Shadow's energy is running low, Katsuki jumps into the air and lands another Explosion on Dark Shadow. Fumikage orders Dark Shadow to grab Katsuki, but Katsuki stops Dark Shadow from carrying out its order with an Explosion and leaps over Dark Shadow, landing behind Fumikage. Fumikage has Dark Shadow protect his back but Katsuki uses his move Stun Grenade before Dark Shadow can protect Fumikage. Thus, Fumikage and Dark Shadow are hit and injured by Katsuki's Stun Grenade. After the smoke clears, an injured Fumikage is on the ground with Katsuki pinning him down. Katsuki tells Fumikage that it's his fault for telling people about Dark Shadow's weakness but admits that it wasn't a fair matchup to begin with. Although he can still get up and fight, Fumikage, knowing that he is at a disadvantage due to Katsuki's Explosions and that Dark Shadow cannot fight properly due to having no strength left, surrenders. Fumikage's surrender causes him to be eliminated from the tournament event.

Fumikage later appears at the closing ceremony of U.A.'s Sports Festival waiting on the podium to receive his third place award. Fumikage notes that the restrained Katsuki looks as if he's ready to bite everyone's head off. Then, All Might arrives to give the winners their medals. All Might gives Fumikage his medal, congratulating Fumikage on his third place achievement. Fumikage thanks him in return, saying his words are too kind. All Might gives Fumikage a congratulatory hug and pat on the back, telling Fumikage that in order to defeat his problem at unfavorable matchups he shouldn't always rely on his Quirk and advises Fumikage to increase his own strength so that he can have a better chance at unfavorable matchups, to which Fumikage says he will comply.

After the closing ceremony of U.A.'s Sports Festival is finished, Fumikage along with the rest of his class are given two off days from school.

Field Training Arc
Two days after the Sports Festival, Fumikage is in class. During the Hero Informatics Period, Shouta reveals the Pro Hero nominations. Fumikage received 360 Pro Hero nominations which is the third highest. Afterwards the Class 1-A has to decide on potential Hero Names. Fumikage writes down and shows his classmates his Hero name. The Hero name Fumikage chose is Jet-Black Hero "Tsukuyomi".

After Class 1-A is finished formulating their Hero names, Fumikage is given his personalized work place list in order to choose a work place that he wants to train at. Afterwards, Fumikage closes his eyes and starts thinking about the work place he wants to train at.

On the day of the workplace training, Fumikage is at the train station with his class so that he can travel to the work place of his choice by train.

The workplace training comes to an end and Fumikage returns to U.A. After Foundational Hero Studies is finished, Fumikage is seen in the boys' locker room.

End of Term Test Arc
In Class 1-A, everyone is talking about the end of term test; Denki and Mina admit that they haven't been studying due to the many events that have taken place throughout the semester, to which Fumikage agrees (admitting that he hasn't studied much either as shown with his low grade). After Katsuki storms out of the class, Fumikage notes that animosity is getting to Katsuki. On the day of the exercise test, Mr Principal reveals that Class 1-A will be fighting against U.A.'s teachers for their exercise test. Fumikage is paired with Tsuyu and they must face Ectoplasm in their test exercise.

Fumikage, Tsuyu and Ectoplasm arrive in an uninhabited city where Class 1-A's test exercise will take place. In one of the city's buildings, Ectoplasm explains the 30-minute test; Fumikage and Tsuyu must either handcuff him or one of them must escape the battlefield within 30 minutes in order to win and pass the test. Tsuyu tells Fumikage that Ectoplasm must be ambushing their designated exit. The test begins; Ectoplasm multiplies and creates four clones of himself that surround Fumikage and Tsuyu. Seeing that they are at a disadvantage, Fumikage orders Dark Shadow to throw Tsuyu onto the next floor which it does. Tsuyu grabs Fumikage with her long tongue and throws him onto the next floor as well. Ectoplasm comments on their nice synergy.

The fight between Fumikage and Tsuyu against Ectoplasm continues with Fumikage being overwhelmed by the sheer number of Ectoplasm's clones. Suddenly, one of Ectoplasm's clones appear before Fumikage. However, Tsuyu smacks it away with her tongue. Fumikage and Tsuyu manage to make it past Ectoplasm's clones and reach the vicinity of the escape gate where the real Ectoplasm is waiting. Ectoplasm compliments the duo for outrunning his clones but asks them if they can deal with his next attack. Ectoplasm uses Forced Internment Giant Bites, a move that creates a giant clone of himself. Fumikage and Tsuyu are unable to escape and the giant clone munches them which traps Fumikage and Tsuyu in its ectoplasm. Unable to do anything, Fumikage orders Dark Shadow to escape as it is now the only way they can obtain victory. Dark Shadow proceeds to the escape gate, but Ectoplasm kicks Dark Shadow away. Tsuyu comes up with a plan and decides to regurgitate something, telling Fumikage to not look so that Ectoplasm does not notice them. Dark Shadow struggles against Ectoplasm. Fumikage recalls Dark Shadow to collect the item Tsuyu has; Dark Shadow collects the item and goes back to fight Ectoplasm. Dark Shadow attacks Ectoplasm with its claw while Ectoplasm blocks it with his kick. However, Ectoplasm's leg is chained by a handcuff; Tsuyu explains that she regurgitated a handcuff since her stomach can store and eject objects and gave it to Dark Shadow so that it could handcuff Ectoplasm with its claw. As a result of Ectoplasm being handcuffed by Fumikage and Tsuyu's last desperate team strategy, they pass the practical exam.

Back in class at U.A., Fumikage learns that he passed the written test and will go to the forest lodge along with the rest of his classmates. Fumikage along with his class go to Kiyashi Ward Shopping Mall to buy necessities for the forest lodge. At the shopping mall, Fumikage advises Izuku to not analyze publicly as it could scare small children.

School Trip Arc
The next day after the shopping trip, at U.A., Shouta informs Class 1-A that the destination for their lodge trip has been changed and the new destination will only be announced on the day of the event. The first semester has come to a close and summer break has begun.

On the day of the event, Class 1-A boards a bus that will take them to the forest lodge destination. An hour later, Class 1-A’s bus stops for a restroom break. However, Class 1-A notes that Class 1-B isn’t at the rest stop. Suddenly, two females wearing cat-like costumes and a small boy appear; the females excitedly introduce themselves as the professional Hero Team, The Pussycats. The black haired female explains to Class 1-A that they will be staying at the base of a mountain which is a part of their domain; they have three hours to reach the base of the mountain using their Quirks as they please and those who do not arrive there by 12:30 pm will not be served lunch. Soon, Class 1-A realize that they have already arrived at their destination and their training camp has already begun with the Pussycats being their supervisors. Some of Class 1-A try to leave, but Pixiebob uses her Quirk to create a landslide of dirt that causes Class 1-A to fall into a forest called Forest of Magic Beasts, which they must traverse to reach their destination. Suddenly, Class 1-A are confronted by a beast; Koji tries using his Quirk to control the beast but it does not work due to the beast being made out of dirt. Izuku, Shoto, Tenya and Katsuki mobilize and use their Quirks to destroy the dirt beast.

After Izuku, Tenya, Shoto and Katsuki destroy the dirt beast, Class 1-A begins traversing the Forest of Magic Beasts. However, the journey through the forest to the Cabin takes around about 8 hours. Class 1-A arrive at the facility, battered and tired. It is now 5:20 pm in the evening. Pixiebob admits that she thought they would take longer to get to the facility; she praises Class 1-A for figuring out her Earth Beasts quickly and easily.

Class 1-A fetch their luggage from the bus and put it in their rooms. Class 1-A go to the dining hall to have dinner. After finishing eating dinner, Class 1-A go to the hot springs. The next day at 5:30 AM, Class 1-A are outside the training camp cabin. Shouta greets his students and tells them that they will undergo reinforcement training to strengthen and upgrade their Quirks which will also allow Class 1-A to obtain their temporary licenses.

Fumikage along with his class undergo training to improve their Quirks. On the night of the third day of training, Fumikage is paired with Mezo for the test of courage. During the test of courage, the League of Villains Vanguard Action Squad begin their attack by filling the forest with poisonous gas. One of the villains part of the squad called Moon Fish ambushes Fumikage and Mezo. Mezo covers for Fumikage but loses one of his tentacles in the process. They manage to retreat from Moon Fish. However, the ambush causes Fumikage to lose control of his Quirk.

Fumikage has been restrained by Dark Shadow, who is now larger and more ferocious due to the power of darkness. Dark Shadow's claw tears through the forest and almost attacks Izuku, who is saved by Mezo. The empowered and berserk Dark Shadow begins taking control of Fumikage's body. Struggling, Fumikage pleads Izuku and Mezo to run away from him otherwise they will die. Izuku watches in shock.

The rampaging Dark Shadow attacks and destroys several trees around it. Dark Shadow attacks Mezo and Izuku, but Mezo is able to dodge in the nick of time. Fumikage pleads Mezo and Izuku to save the others and forget about him; he tries controlling the rampaging Dark Shadow but to no avail as he starts becoming immobile as a result of Dark Shadow's greater control over him. Izuku and Mezo manage to lure the rampaging Dark Shadow to Katsuki and Shoto's location. When Moonfish tries attack Izuku and Mezo, the rampaging Dark Shadow appears and uses its enormous claw to crush Moonfish, destroying Moonfish's teeth and injuring him. Shoto and Katsuki are surprised at what happened.

However, Moonfish gets back up using his teeth and is enraged, shouting that only he is allowed to harm the kids. Moonfish attacks the rampaging Dark Shadow with his teeth, but Dark Shadow is not affected or even harmed by Moonfish's counterattack. Dark Shadow grabs Moonfish and smashes him through several trees, which heavily injures Moonfish and incapacitates him. Dark Shadow throws the incapacitated Moonfish aside. With Moonfish defeated, Katsuki and Shoto manage to get close to Fumikage and use their Quirks, which calms down Dark Shadow; Dark Shadow reduces in size and retracts back into Fumikage, allowing Fumikage to regain his mental and physical mobility.

Now back in control, Fumikage thanks Katsuki and Shoto for saving him. Mezo is glad that Fumikage is fine. However, Fumikage is regretful that he couldn’t conceal his anger when Mezo lost one of his arms, which caused him to release Dark Shadow out of anger and lose control due to being enraged and spurred on by Dark Shadow’s own rage. Fumikage is guilty for harming Mezo; Mezo tells Fumikage that he doesn’t need to feel guilty.

Izuku tells Fumikage that their top priority is to protect Katsuki, who is the target of the villains'. Izuku decides that they should escort Katsuki back to the facility and take a shortcut through the forest todo so; Izuku thinks that with the power of Mezo’s scouting capabilities,Shoto’s powerful Quirk and the unrivaled power of Fumikage's Dark Shadow, escorting Katsuki will be a cinch. However, Katsuki is angry that he needs protecting and refuses their help. The Bakugo Escort Squad (consisting of Mezo, Shoto, Izuku and Fumikage) begin escorting a begrudging Katsuki back to the facility.

The Bakugo Escort Team travels to the facility and comes across Ochaco and Tsuyu. When Ochaco and Tsuyu notice that Katsuki is not with them, Izuku, Mezo and Shoto turn around and see that not only Katsuki has disappeared but Fumikage as well.

It is revealed that the magician villain, Mr. Compress, kidnapped Fumikage as well due to being impressed with his victory against Moonfish, stating that he will be very useful. Izuku, Mezo and Shoto chase after Compress in order to rescue Fumikage and Katsuki.

Izuku, Mezo and Shoto land along with Mr. Compress at the Vanguard Action Squad's rendezvous point; they engage in battle against Himiko and Twice until Kurogiri arrives to retrieve the Vanguard Action Squad. Mr. Compress reveals that he hid the real marbles containing Fumikage and Katsuki in his mouth. Mr Compress slowly enters Kurogiri's Warp Gate. Suddenly, Yuuga fires his Navel Laser at Mr. Compress's face, breaking his mask and causing Mr Compress to spit out Katsuki and Fumikage. Mezo manages to rescue Fumikage while Shoto nearly rescues Katsuki only to be snatched away by Dabi. Dabi, Mr Compress deactivates his Quirk which frees Fumikage and Katsuki. Fumikage, now free, sees that Katsuki is teleported away against his will.

Fifteen minutes after the Vanguard Action Squad's attack, the training camp ends and Fumikage returns home. Two days later, Fumikage along with Class 1-A, visit Izuku who is in a hospital near the training camp. Fumikage apologizes to Izuku for causing him trouble during the Vanguard Action Squad's attack, althoug Izuku rebuffs Fumikage's claim and admits that it is his fault. Fumikage listens to Eijiro stating that Momo along with Yousetsu managed to plant a transmitter on one of the villains and thinks that Class 1-A should rescue Katsuki themselves.

However, most of Class 1-A are against the idea of attempting to save Katsuki themselves and agree with Tenya. Yuuga suggests that they leave Katsuki's rescue to the Pro Heroes since they have been prevented from partaking in combat. Fumikage agrees with Yuuga and does not say anything else regarding the matter since he is in no position to state his thoughts after being saved many times. The doctor arrives and asks the class to leave the room so that he can talk to Izuku privately. Fumikage leaves the room.

Hideout Raid Arc
Fumikage watches the broadcast of the battle between All Might and Sensei on his computer.

Quirk and Abilities
Dark Shadow (黒影 (ダークシャドウ)): Fumikage's body is host to a shadow like-monster that he can materialize from his body and contract it back into his body freely. Fumikage can use the shadow-like monster for a number of purposes, such as attack, defense and support. This shadow-like monster has shown to be sentient. The shadow-like monster has an energy limit that is drained due to bright settings and when it runs out, the shadow like monster will retract back into Fumikage. According to Mezo, Fumikage's negative emotions (such as regret and indignation) probably intensify Dark Shadow, making it more unruly and possibly making Dark Shadow stronger as a result, albeit at the cost of Fumikage losing control; Fumikage himself stated that his anger causes him to lose control of Dark Shadow.

The personality, strength, defense and control of the shadow-like monster depends on the lack of light on Fumikage's surroundings. During the day, Dark Shadow is weaker and smaller in size but still has considerable strength and defense as well as easier to control. During the night, Dark Shadow is stronger and bigger which grants it great strength, defense and size, powerful enough to rip out and cut down multiple trees with ease. However, Dark Shadow is more difficult to control at night, causing Fumikage to lose control.

Moves

 * Black Ankh: Fumikage's special move (previously known as Tenebrous Abyss Body (深淵闇躯). Fumikage dons and equips Dark Shadow onto himself, wearing it like a suit of armor or an exoskeleton. According to Fumikage, equipping Dark Shadow onto himself mitigates his physical weaknesses.
 * Piercing Claw of the Dusk: Fumikage shoots out Dark Shadow's claw which attacks at great speed.
 * Gloom of the Black Arm: Fumikage shoots out both of Dark Shadow's claws which attack at great speed and then uses Dark Shadow's claws to surround his victims.

Overall Abilities: Fumikage is said to be one of the strongest members in Class 1-A. He was able to defeat Momo Yaoyorozu (a person who was accepted into U.A. through official recommendations). Izuku Midoriya remarked that Fumikage is one of the strongest people when it comes to one-on-one battles. Fumikage has shown to be strategical, as he ordered his Dark Shadow to guard his team's blind spot during the Human Cavalry Battle and grabbed one of Shoto's headbands when the opportunity arose. Fumikage managed to hold off Katsuki Bakugo for some time, one of the strongest members in Class 1-A, despite having a Quirk type disadvantage and even when his Dark Shadow was not at full potential. All Might himself acknowledged Fumikage's strength and gave advice to him on how to improve. Shoto Todoroki was amazed with Fumikage's strength after witnessing his Dark Shadow pulverize and defeat Moonfish, a villain that kept him on the defensive.

Ectoplasm
Ectoplasm is a hero and the teacher who Fumikage and Tsuyu battled against for the End of Term Test.

Katsuki Bakugo
It appears Fumikage and Katsuki are on neutral terms with each other as they neither hate or are friendly with one another. They first interacted during the semi finals of the Sports Festival tournament where they faced each other. Katsuki appeared to enjoy the fight with Fumikage despite Dark Shadow being annoying, although Fumikage isn't too fond of Katsuki's savage fighting style but doesn't appear to hate him for it. Despite what he thinks of Katsuki's aggressiveness, he was nonetheless thankful towards Katsuki for helping him regain control over Dark Shadow during the training camp. Katsuki also expressed some disappointment that their Quirks had bad chemistry, possibly indicating that Katsuki views him as a worthy opponent.

Koji Koda
They fought the League of Villains together during the Ultimate Space and Jams Arc, so Koji is one of the people who knows Fumikage's weakness.

Izuku Midoriya
They teamed up along with Ochaco and Mei during the Human Cavalry Battle. Fumikage respects Izuku as a leader, as he leaves him with making the decisions of their team. Izuku himself respects Fumikage's strength and the power of his Quirk, acknowledging him as one of the strongest combatants in Class 1-A. During the training camp, Izuku along with Mezo resolved to save Fumikage from his rampaging Dark Shadow in which they eventually succeeded. After Fumikage is kidnapped by Mr. Compress, Izuku chased after the villain in order to save Fumikage.

Tsuyu Asui
Fumikage is sometimes teamed up with Tsuyu; they were teamed up together during the Battle Trial and End of Term Test. Both Fumikage and Tsuyu mutually respect each other, and have great teamwork despite not often interacting.

Mezo Shoji
After Mezo lost one of his arms due to Moonfish's ambush, Fumikage lost control over Dark Shadow and harmed Mezo in the process. Izuku along with Mezo resolved to save Fumikage from his rampaging Dark Shadow in which they eventually succeeded with the help of Katsuki and Shoto. Fumikage felt guilty for harming Mezo and apologized; Mezo shows no ill will towards Fumikage, thus he and Mezo are on good terms with each other. After Fumikage is kidnapped by Mr. Compress, Mezo chased after the villain in order to save Fumikage. Mezo manages to grab Fumikage's marble form after Mr. Compress spits him out due to Yuga's Navel Laser, thus Mezo saved Fumikage from the League of Villains' clutches.

Shoto Todoroki
Fumikage and Shoto haven't properly interacted with each other. However, during the training camp when he lost control of Dark Shadow, Shoto and Katsuki used their Quirks to help Fumikage regain control over Dark Shadow. Fumikage thanked Shoto for saving him. Shoto was amazed with the strength of Fumikage's Dark Shadow against Moonfish. After Fumikage was kidnapped by Compress, Izuku, Shoto and Mezo with the help of Ochaco and Tsuyu chased after Compress in order to rescue him and Katsuki in which they succeeded in saving Fumikage
