OMORI

This can be only obtained during the TRUE ROUTE. During Three Days Left, and continuing the story, you will encounter Kim and Vance trying to steal candy. After being told off for being shoplifters, you have to fight them outside the shop.

During the fight, DO NOT attack them, let them hit you until you're knocked out. Don't worry, the story will continue as normal, they'll still tell you where Aubrey is, just there will be some different dialogue and they take the big bag of candy from Kel.
