Fumikage Tokoyami, also known as Tsukuyomi, is a character from My Hero Academia and is a regular reoccurring character in The Knights of the Multiverse. He's a student in Class 1-A at U.A. High School, training to become a Pro Hero. He and his classmates also frequently tutor Class 2-K.
Fumikage is reserved, serious, and focused, albeit noble and valiant as well. Though he does not talk very much, he will directly ignore questions or requests that seem in some way pointless (like sitting on his desk when not in the middle of a lesson) 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's very fond of darkness and other related concepts, considering himself a "creature of the dark" and employing archaic-sounding speeches that end up painting him as slightly creepy or dramatic. Nevertheless, he is a bit insecure about his interests due to them being more on the arcane, fantastical side, and thus harder for others to understand or relate to.
Fumikage also possesses a great amount of humility, being aware of his own limits and understanding when it's time to back down. He takes any advice he gets seriously and uses it to try and improve on his Quirk and abilities, showing great determination to even keep up with the top heroes. Fumikage thinks little about fame and idolatry, but is still prideful enough to not tolerate being looked down by others.
