Aegis in the Dark

 (Yami no Aegis) is an original manga written by Kyouichi Nanatsuki and illustrated by Yoshihide Fujiwara. The story is about Tate Karito, a former policeman who lost his wife, son, and right arm at the hands of a terrorist named Butterfly. After gaining a prosthetic arm capable of deflecting bullets, he became the "Aegis"&mdash;a "Protector" who neither kills nor assists in killing&mdash;in hopes of one day tracking down the man who slew his family.

It is a sidequel to the 1992 manga JESUS, and several characters and settings from the work appear in Aegis in the Dark. Both works were also adopted into Hiroshi Takashige's Until Death Do Us Part. While a sequel to this work, Aegis in the Dawn, was written in collaboration with Takashige along with JESUS Sajin Kouro, Aegis in the Dawn is relatively detached from the overall fictional universe and primarily focuses on Tate's continued fight against Butterfly.
