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 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. During combat, Fumikage is known to be fierce and dependable, with his strength and capabilities rarely being questioned. Fumikage is 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, Fumikage 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. Regardless of his association with dark themes, however, Fumikage does not show any sort of villainous behavior at all. He greatly cares for his friends and mentors, and should harm come their way, Fumikage may end up feeling enraged or indignant, which can lead to disastrous consequences due to his Quirk being sensitive to his emotions. Fumikage also possesses a great amount of humility, being aware of his limits and understanding when it's time to back down. He takes any advice he gets serious and uses it to try and improve on his Quirk and abilities, showing great determination to even keep up with top heroes like Hawks. Fumikage thinks little about fame and idolatry but is still prideful enough to not tolerate being underestimated or looked down upon by others.
