Angel Player

Angel Player is a technologically advanced computer software that only exists in the Afterlife. It contributed to the creation of K.T's and Michael's Guard Skill abilities and was responsible for the manifestation of Shadows in the past.
==Trivia==
*In the past, the SSS leader, Yuri Nakamura, believed the AngelPlayer program was created by the Programmer; an unnamed human that turned himself into an NPC after he went insane waiting for the girl he loved to return to the Afterlife.
**However, evidence has shown in Chapter 7 that it may have been created by The Girl that Isn't and likely was a cover-up by The AI to prevent the SSS from knowing who she truly was.
