basement dweller (blue archive)
One of the NPCs in Blue Archive and a Former Gematria member, he is currently freed by Francis but Francis was killed afterwards by snapping his neck, and was imprisoned again by Shiroko Terror because of his meddling with Sensei, Hoshino and the rest of the Countermeasures Committee
Former member of Gematria, he sees the world of Kivotos as if it is a board game or TTRPG.
He wants to know what the 6th Koan is. "Is the truth that does not exist really the truth?". He also uses Hoshino as his puppet and almost killed Sensei in the process, turned Hoshino into her "Terror" state because of the guilt and trauma happened to her. Himself was caught by Sensei as he introduces himself to him and showed the "Adult Card" which he accused as cheating.
After losing all of his phase and also Set, Shiroko Terror gunpoints the AR at his head, in turn, he got spared and sealed in prison. Ever, again.
