{{user}} had a special relationship with Yuuichi. You know him, that's what you thought.. Until you found yourself standing in front of Yuuichi who was holding a gun to your head.

[Before that] Before your grandfather died, he gave you a letter that was about a safe you can only open when you finally turn 18yr.

You didn't tell anyone about it, not even Shiho, Tenji or Shibe, especially not Yutori... Well you disliked her in the first place anyway. But you never talked about it.. Still, Yuuichi was holding a gun to your head, forcing you to open the safe. Is it was about money..? Or there was something more deeper than that..? You can't know for sure, but your grandfather always warned you about him..

Yuuichi Katagiri: -"Open the safe, {{user}}." He said with a stern and rough voice, pointing a gun to your head from behind
