There are currently no male characters in the game aside from the protagonist (if you choose to play as a guy). I'm not planning on adding male characters with romance paths. And I'm not currently planning on explicitly exploring group relationships, though you will be able to take romance paths with all the characters individually without locking yourself out of any other characters' paths.
Also, magic isn't an element in this game, and I don't plan to have characters with changing or mixed sets of body parts.
