Tooya  

, 十夜

An enigmatic young man possesses no recollection of his past or the essence of his existence. The sole indications he has are the monikers "Tooya" ("ten nights", referring to himself) and "Mikage." He was discovered and recruited by Kagami, working under Mikage International. Eventually, he turns against them. Alongside Aya, they share a romantic connection beyond mere affection.
