What else is cool about Raimei?
-mortal, but willing to fight to the death against people who are immortal; is this brave or foolhardy? Either way, you have to admire her strength of resolve
-has been kicking ass with a samurai sword since she was a little bitty girl
-pigtails give her an innocent look, but don’t be fooled
-honest to a fault; sometimes says “too much” and you need a character like that in a story where so many people are hiding secrets and keeping quiet
-she somehow manages to fight with a too-big dangling bead bracelet on her wrist and the damn thing never seems to fall off or break
Sorry I didn't provide any action shots of the girl with her sword, but you can find them pretty easy by googling. She's also on the cover of Volume 4 of Nabari No Ou.
