Fumikage Tokoyami/Relationships

Izuku Midoriya
Their friendship is built upon a mutual respect towards each other. They teamed up along with Ochaco and Mei Hatsume 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. They later sat beside each other to watch the sports festival tournament. Izuku later cheered on Fumikage and Tsuyu during their Exam against Ectoplasm.

During the training camp, Izuku along with Mezo Shoji 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 as well as Bakugo. After Bakugo was captured, Fumikage tried to comfort Izuku.

Tsuyu Asui
Although their interactions in the classroom have been minimal, Fumikage has been with Tsuyu a number of times. They worked together during the battle trial and the practical section of their final exams.

Fumikage and Tsuyu agreed to strategize prior to their practical exam, showing they had strong communication with one another. During their test against Ectoplasm, Fumikage and Tsuyu displayed elite synergy and teamwork. Their Quirks work very well together in both evasive and combat situations, and Tsuyu can compensate for Fumikage's weaknesses. Although they were overwhelmed by Ectoplasm, they managed to pass their finals.

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.

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 Unforeseen Simulation Joint Arc, so Koji is one of the people who knows Fumikage's weakness, in fact Koji was the first in Class 1-A to learn Dark Shadow's weakness.

They also showed good cooperative skills with each other during the Provisional Hero License Exam.

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
