Togari, Volume 4 — Yoshinori Natsume

Tobei's magical sword Togari derives its great power from the evil of its wielder. So what's a fiend looking for redemption to do when he discovers that performing a good deed causes his weapon to fail him? While Tobei is puzzling over this, he comes face to face with an evil unlike anything he's ever encountered before--a man with a blinding-white aura of ice-cold darkness.
