Kuroyami

Kuroyami is the slash ship between Fumikage Tokoyami and Shihai Kuroiro from the My Hero Academia fandom.

Canon
Fumikage and Shihai are both students at UA High School, Fumikage in Class 1-A and Shihai in Class 1-B. The two have similar Quirks, both utilizing the darkness.

Fumikage and Shihai are first shown together in the Joint Training arc, although they would have met each other prior. They are paired on opposing teams for training, and are the second round of matches. Shihai speaks to Fumikage, mentioning how the two of them are very similar. Fumikage agrees, although seems unfazed by Shihai's comments. Shihai continues, calling them "brothers in the shadows". Fumikage seems to then truly recognize Shihai as one of his own, asking if he has also "stared into the abyss".

As the match begins, Fumikage sends Dark Shadow ahead to scout the enemy. However, Shihai quickly overtakes Dark Shadow using his Quirk, then uses Dark Shadow to attack Fumikage. He then calls out to Fumikage again, saying that the two of them share a destiny. Fumikage agrees, calling them rivals. He then announces his newest move, "Dark Fallen Angel". Shihai laughs at the name and calls it "dramatic". He then grabs Yuga Aoyama, forcing Fumikage to fly after them. Although Yuga is captured, Fumikage refuses to give up. He manages to pin down both Shihai and Kinoko using his Quirk, trapping Shihai in the darkness of his cloak. Fumikage is seen holding the cloak tightly in his hands, with Shihai's eyes blinking out at him. Despite all this, however, Shihai's team manages to win the battle.
