Moyuru Tochi/Synopsis

Vigilantes Beginnings Arc
Moyuru Tochi meets Koichi Haimawari when he accidentally bumps into him and his friends and spills Soga's juice. They try to humiliate Koichi by having him kneel down to them, but he runs away using his Slide and Glide Quirk. They chase him, but Koichi manages to escape. Later, they encounter Koichi again at the convenience store he works at, and this time they beat him.

Later that night, Koichi and Kazuho Haneyama meet the thugs in an alleyway, and they recognize the latter as the online idol Pop☆Step and pin her to a wall while expressing their intentions to sexually assault her. Koichi tries to stop them but is about to be killed by Soga. Suddenly, Knuckleduster appears to help him and defeats Soga, Moyuru and Rapt with ease, but not before asking and checking if they have a black coloration on their tongue.

Wounded and bruised, the three thugs move away. Soga expresses desire to take revenge on Koichi and Knuckleduster, although his friends try to convince him otherwise. At that moment, Mario Kugutsu appears, offering them samples of Trigger assuring them that their wounds will be healed.

The next day, while doing their duties as Vigilantes, Koichi, Kazuho, and Knuckleduster approach Mario, who Knuckleduster suspects of being a Trigger dealer and try to arrest him by force. Koichi and Kazuho think he is rushing into his accusations, but Knuckleduster is about to hit him, being stopped by Eraser Head, starting a fight between the two.

While this happens, Mario escapes, and Kahuzo realizes that there is something fishy about him and chases him along with Koichi. During the chase, they meet again with Soga, Rapt and Moyuru, who came to take revenge. They take a dose of the drug that Mario gave them, transforming into Instant Villains. While Soga and Moyuru attack Koichi, Rapt goes after Kahuzo, who is still chasing Mario. Moyuru and Soga corner Koichi and taunt him, but Knuckleduster knocks out Moyuru by slamming a brick against his head. Moyuru and his friends' Quirks are nullified by Eraser Head, who promptly subdues and arrests them.

Stendhal Arc
Moyuru and Soga are released after serving their sentence, and go to the hospital to visit Rapt, who is still recovering from his injuries. Moyuru brings him soda and manga as presents, although what Rapt really wants is to smoke. The three must leave the room when a nurse catches them in possession of a pack of cigarettes.

Once in a secluded area to smoke, Rapt says he will be discharged soon. Moyuru is impressed that he has healed so quickly from his injuries, and Rapt attributes this to the healing abilities of his Lizard Quirk, although he believes Trigger also helped in. When talking about the drug, Rapt recalls how it boosted his Quirk to the point of granting him wings that allowed him to fly. Moyuru says that that was impressive, and that in his case, the drug just added more firepower to his Flame Quirk. Rapt tells him he looked awesome, comparing him to Endeavor.

When Soga asks Rapt if he would like to fly again, he replies no. Rapt admits that the Trigger he took made him feel powerful, he doesn't want to go through trouble like that again. Moyuru thinks the same as his scaly friend.

Unbeknownst to him and Rapt, Soga reunites with Kuin Hachisuka, the main person in charge of distributing Trigger in Naruhata, and demands her to leave his friends out of everything related to the drug. However Kuin has other plans for them as she had allied with the murderous vigilante Stendhal to kill them. Thanks to the intervention of Koichi and Knuckleduster, Stendhal is defeated.

Vs. Queen Bee Arc
After the incident with Stendhal, Soga becomes an ally of Knuckleduster, and helps him in his search for the whereabouts of Kuin Hachisuka, without saying anything to Rapt and Moyuru. One day, while researching at her high school, Soga falls into a trap of hers using a girl controlled by her parasitic bees.

Fortunately for Soga, Rapt and Moyuru arrive on motorcycle just in time to help him. Moyuru uses his Quirk to set Kuin's bees to ashes as Rapt helps Soga to hop on the scooter. While fleeing, the two friends ask Song about his recent actions, to which he tells them that it doesn't have anything to do with them.

They go to the hospital where Knuckleduster is visiting, terrifying Rapt and Moyuru. After informing him of new intel, the three head off and run into Koichi and Kazuho. Koichi holds no grudge against them while Kazuho is still angry with their attempted assault. Moyuru notices how brave he is to talk with the people who beat him up before, calling him "big man."

Sky Egg Arc
Knuckleduster asked Soga, Moyuru and Rapt to take care of his hospitalized daughter Tamao while he is out, and during that time they soon become friends. One day, Rapt cramps his tail while attempting to play the guitar, amusing Tamao and his friends. Moyuru and Rapt are terrified when Knuckleduster comes into the room, though he leaves rather quickly.

When Soga tunes Tamao's guitar and encourages her to play it, Rapt and Moyuru joyfully tease Soga for being a "sweetheart", much to his annoyance.

Final Performance Arc
Shortly after Koichi is knocked out after his confrontation with Bee☆Pop, Soga takes him and leaves him in Rapt and Moyuru's care at Moyuru's parents' place. Koichi wakes up, and the two feed him porridge. As Rapt remembers to turn on the news, Koichi remembers about Kazuho's bombings that night. Soga returns and hands Koichi a letter from Knuckleduster, which helps restore Koichi's resolve to save Kazuho, though he dubiously answers he doesn't know where to start, causing Moyuru and Rapt complain about his lame answer. Soga smiles at Koichi's determination, which Moyuru and Rapt poke fun at.

Soga leads Koichi, Rapt and Moyuru to Knuckleduster's warehouse, explaining that they are free to use whatever is in there. Rapt is excited to grab a loaded shotgun, making Moyuru uncomfortable. Soga explains his plan to rescue Kazuho, which involves breaking numerous laws, something Rapt finds fun but Moyuru finds upsetting. Rapt and Moyuru help record Koichi's stamina test, expecting him to crash. To their incredible surprise, Koichi not only slides super fast, but stops with incredible control. During Koichi's accuracy test, Rapt throws up several cans, which Koichi pierces using his Shooty-Go-Kablams with impeccable accuracy. Shocked at Koichi's power, Moyuru and Rapt cower as Koichi seemingly points his hand in their direction.

As they continue training, Rapt and Moyuru notice that while Koichi can shoot round targets just fine, he misses the human-shaped targets. As Soga suggests that Koichi subconsciously trained to miss people, Rapt nonchalantly suggests having Koichi practice shooting others while pointing at Moyuru, annoying the latter. Over the next several days, Rapt and Moyuru help Koichi train his Quirk while Soga formulates a plan. When Soga planned to stay up all night to find decent footage of Kazuho to analyze, Moyuru suggested that he take a break and let him find videos instead. While looking for videos, Moyuru points out that helping people is fun.

One day, they notice an explosion in Naruhata, prompting the four to move out and search for Kazuho. As traffic is jammed, Koichi moves on ahead while Soga, Rapt and Moyuru find another way into the city. They notice sirens ringing, signaling Endeavor's arrival. That night, Koichi, carrying an injured Kazuho in his arms, heads over to his allies' position to remove the Queen Bee. However, they are worried when Koichi reveals that Kazuho has been shot with a pheromone, throwing their plans into doubt.

Before Soga can extract the Queen Bee, Midnight arrives to help Kazuho. They explain the situation to her, so she tells them to cover their mouths as she uses her Somnambulist Quirk to put Kazuho and the bee to sleep. However, Rapt couldn't hold his breath and was knocked out by the gas. They are surprised with the arrival of Endeavor, who plans to take in Kazuho and The Crawler. Midnight convinces the Flame Hero that Kazuho is captured and that Koichi escaped, so he lets them take her to a hospital.

Moyuru and his friends are later interrogated by Naomasa Tsukauchi, who takes note of their conflicting alibis about how they encountered Kazuho Haneyama. Eizo Tanuma later lets them go, and so they regroup with Koichi at Knuckleduster's warehouse. Soga comes up with a new plan to guard Kazuho's hospital via their own security checkpoint to prevent Number 6 from getting further to her. Moyuru nervously asks what would happen should they encounter the villain for real, to which Soga assures that they should run, making him more concerned with the chance that the villain could murder them right on the spot.

Naruhata Lockdown Arc
Some time after Number 6 attacked the police station and put Eizo in critial condition, Naomasa confronts Moyuru and his friends, declaring that they will take over with security from this point on. As Naomasa demands they call Koichi, Soga tells Moyuru to give him a wake up call to escape, and then runs from the police. That night, Number 6 initiates his "Operation Anonymous" by cutting off power throughout Naruhata. Number 6 invades the hospital, accompanied by several Anonymous. Rapt and Moyuru help carry injured police officers to safety, and Rapt reassures the worried Moyuru that Koichi and Soga will figure something out.

Rapt and Moyuru are confused when the Anonymous stand still and wander around the hospital premises but are nonetheless uneasy as Number 6 goes in alone. When Number 6 comes out, the two are disturbed at his talking to himself, but are surprised to see Koichi blast off away from the hospital. Koichi, however, returns, ready to face off against Number 6 himself. As Koichi gets knocked down by Number 6's explosive punches, Rapt accidentally gives away his and Moyuru's location pointing out that Koichi might lose. As Number 6 gleefully tells Rapt and Moyuru to wait for their turn, Koichi comes back and neutralizes his explosive punches by creating shields using his Quirk.
