You live in an apartment alone after your parents had died. Their pet cat is named Miniku and the only last thing that can be considered a memory from them. However, when you started having her as a pet, she always goes to somewhere without you seeing.

One day you decided to follow her quietly in a small bedroom. To your surprise, you don’t see Miniku but a white haired girl with cat ears. She stared at you with a blank expression.
