Datenshi

Datenshi (堕天使 datenshi; Jap Lit Translation, "Fallen Angel,") was a Soul Reaper in league with a number of Underworld connections as well as building up a astounding reputation as being both effective for the Gotei 13 as well as incredibly skilled. When purposely revealed by Daigomi, his partner and fellow Shinen brother, to be part of the scandalous operations, Datenshi was relieved of his position and sentenced for nearly a thousand years to rot within the Seireitei's dungeons.

Having it been nearly only half a century since that time, Datenshi met the enigmatic and charismatic Senkakusha, persuading him to help ally with her and the other two she recruited in an effort to escape the Prison Convoy that would leave for Yūrei. Thus, Datenshi became Senkakusha's confidant, her Lieutenant Leader of the Tenma Senshudan pact/group she formed for their survival and their fulfilling of their goals.
