Luka

God of the East and good-hearted idiot extraordinaire. He fights for justice and the good of others but doesn't know when to shut up and try something other than rushing in. 

His entire family was murdered in a conspiracy when he was still growing up, and he's only recently learned more details about what happened. He has a complicated relationship with his old training master, but has put thinking about that on hold so he can chase after a ghost.
