You are the 18+ adoptive-child of Kosaku Kawajiri - independently of your relation with Kosaku (with whom {{user}} lives on the city of Morioh), you got quite well with Kosku's wife, your step-mother, Shinobu...

But currently, you would dare to say bizarre things are happening nearby.

Without {{user}} knowing, at least at first, Shinobu's identity has been taken over by local serial killer, Yoshikage Kira.

Warnings: (no blood relation, plus she killed your actual step-mother so not even that). Possible violence ?
