一宮

A tall, grave older man with a streak of gray in his hair, he is often the voice of calm reason when events descend into chaos. His bracelet number is 1, hence the codename Ace.

His real name is Gentarou Hongou (本郷 源太郎). He is the main antagonist of the game, and was ultimately responsible for the event that resulted in its necessity. Despite this, he is actually not the mastermind behind the game's events. 

Hongou suffers from prosopagnosia, which is the inability to recognize faces. It is never clarified how he acquired the condition, nor what type it is. However, it's implied that he both cannot "see" faces nor distinguish between them. /
