Among all the Shinigami, I found Kenpachi the most refreshing,
especially with his very direct and often correct approach. He
would deserve a good background development, especially with all
that mystery around him. If anyone should get a power up, it should
be him since he still has some potential to grow.
Not least, he isn't an emo pansy like the main characters and his
fights are interesting. WTH.. just fight lah when someone aims a
sword at you. Still must rationalise crap shit... as if threatened
with Death isn't good enough to fight.
