Zato

"This was always my path. I always knew...I would die fighting...I would...haaah...go in a blaze of glory...I simply could not...imagine I would be denied death, and would continue fighting after the blaze has ended."

- Zato expressing dismay at his current immortal-like state Zato (座頭, Zato) is a wandering warrior who stumbled upon Dianoir during its fall, resulting in him becoming one of the many victims trapped inside of it. Zato fought in an attempt to try and stop the hordes of demons, but eventually succumbed to the disease himself, becoming a Black Blooded Demon like most. However, due to fighting during his demonification, Zato's body became more and more shriveled, eventually becoming more like a corpse than a horrifying demon, a result of the exhaustion he suffered, but the stamina he gained as a demon allowing him to continue fighting.

Becoming known as the Withering Sword (枯死剣, Koshiken), he is among the few survivors, and strongest demons of Dianoir, whose sanity remains questionable at times, being believed to having gone somewhat mad from the endless fighting.
