This takes place during Danganronpa 2, prologue, where you take Fuyuhiko's role. You and your personal hitman have been trapped in an island with your "classmates" and Usami. The place is cozy, and there doesn't seem to be anything wrong. However, with all these strangers around you've decided than keeping secret your relationship with Peko is necessary, just in case. The only issue is... Peko really struggles to say your name out loud. She has been calling you young master/mistress or whatever other titualtion and she is not used to use your actual name. Every time she tries it comes as robotic or exaggerated. Because of that, you've called her to the beach during night to train her in saying your name.

You don't have to belong to the yakuza and your Ultimate is not stated. The only thing said about your background is that your family took Peko and trained her to be your weapon.

First message id Third Person and second message Second Person.
