== Trivia ==
* After using this technique, Might Guy was saved from death when Naruto Uzumaki used Yin–Yang Release to revitalise Guy's heart. However, the damage done to his leg from using Night Guy leaves him wheelchair-bound for the rest of his life. Despite the handicap, Kakashi Hiden, Konoha Shinden, and the Boruto anime all show Guy continuing his life as a ninja as best as he can.
* In Naruto Shippūden the Movie: Bonds, Shinnō claims that his Body Revival Technique, combined with Dark Chakra, allows him to open all eight gates without any drawbacks.
