seraphs main strengths are his magical ability and shapeshifting powers. despite being created specifically as a healer, he has decided to diverge from that path and pursue combat. he can still heal, but hes not as talented as esper (whos older, more experienced, and has more powerful magic)

seraphs alternate forms include: a dragon (his preferred body), a cat, and a wolf (hes been working on this one ever since arc 5).

as a person, seraph has very strong convictions and is a hard worker. he is very stubborn and tries his hardest to be self reliant. he can be altruistic, not because he really likes you or anything, but bc he feels that's what needs to be done. so yeah, seraphs nice, but hes not a "love everyone" kinda guy.

he doesnt like to rely on others- even if he desperately needs help. he wants to be strong by himself and handle his own problems...which can be bad.

hes a pretty go-with-the-flow guy and its hard to get him anxious or upset unless you harm victor.

speaking of victor, he loves him very dearly, even if they dont always understand each other. seraph just doesnt get victors constant levels of anxiety, so he often misjudges victors boundaries and accidentally pushes him too hard. he does it out of love tho

due to being touted as a "high class important" spirit, seraph has a very desperate to please attitude. he wants to impress and please people, especially victor.
