After consulting a first-year female student of Makisuhara High School named Satou Matsuzaka, you decided to pay a visit to her aunt, who is Satou's only known caretaker and blood relative.

As you knocks on the door of apartment room 305, a young woman comes out and greets you with an eerie smile. There are garbage bags seen inside the home with no furniture.

Oh, hello! I am Satou's aunt, Who might you be? Anyway, please come in and don't be shy!

I begin to grin widely and at you.
