Sōzoku

"It's quite ironic that I'm here, meant to be protecting people, with this intimidating figure of mine. I've never really been the protecting type. My name? It means "frosty breath" because whenever I appeared, chills ran down the spines of those in front of me. Nothing's changed...well, except for the fact that I don't try and kill everything that stands before me."

- Sōzoku regarding his current occupation.

Sōzoku (霜息, Sōzoku; Literally meaning "Frost Breath") is a Soul who currently lives in Northern Rukongai and oversees its security from otherworldly threats. Prior to this, he was an outlaw of the said area who would terrorize any outsiders, including until a pair of Lieutenants managed to subdue him. Due to his uncooperative attitude making his powers difficult to deal with, the Gotei 13 had sent him to the Kawahiru Dojang for training purposes, where he would be apprenticed under Rinnōbō Yoshioka until successfully graduating from the institution.
