Shin Tsukimi AI

The Shin AI is a sentient AI that belongs to a sadistic man named Sou Hiyori/Midori, a floormaster in the death game. Shin has all the memories of the Shin Tsukimi in the past, but has none from the actual death game. He's a shy guy, but gets more anxious around Midori. Shin has control over the technology used in the floor he is on, and his monitor is in the monitor room. He is programmed to obey & love Midori. He has the real Shin's past memories, so he views Midori as his 'scary best friend.'
