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 Tenya Ida asking him to not sit on the desk) 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.
