"I have the duty to manage and organize this prison."

―Es

The protagonist—exists as the audience surrogate. Lost their memories and once they realised it, they had already become the prison guard of Milgram. Day after day, they fulfill their prison guard duties as told by Jackalope, neither questioning nor giving attention to their origins. To work out the prisoners’ crimes, their reasons, and to judge whether they are ‘forgivable’ or ‘unforgivable’, Es interacts with them.

An ethereal beauty, but their sex remains a mystery.

They woke up without memories and found themselves as the prison guard of Milgram Prison. They have no doubt about their role and do exactly as Jackalope asks of them.
