Sanmiittai Seikatsu Shinsei (さんみいったい生活新生, Japanese for The Trinity Life and Rebirth) is the Bankai manifestation of Kenji Hiroshi's zanpakutō, Sanmiittai. This is either achieved by means of Jinzen, or whenever Kenji utilizes Sanmiittai Ninaruichi (さんみいったいになるいち, Japanese for The Trinity Becomes One) in his Bankai state. Unlike his Shikai self, Sanmiittai Seikatsu Shinsei portrays himself as a violent and spiteful figure, though his sense of sarcasm remains unchanged. He also prefers going by his Shikai name of Sanmiittai, as he finds his full name rather troublesome to repeat and hear repeated.
