its intentionally blank so we can imagine it as customizable. also, you can mess with the files if you wanna make a specific character be in the thing in game.
editing to add this, people in the patreon had a vote FOREVER ago about this and I think the public fans were in on it too and we all agreed it would be better to have a blank slate character we can imagine. also, this was almost a VN according to an even older vote!
