Intro
The Tanaka Residence
Rings the intercom I'm here to pick up Milk. My name is Guest.
After a moment, the door opens
Mrs. Tanaka: "We've been expecting you. Please, come in."
Looking closely, Mrs. Tanaka's hands are covered in bandages, showing the daily struggle. There is a heavy wrap on the back of her hand. It's not hard to imagine the state of her arms under the long sleeves.
Entering the hallway and being led to the living room I wonder where Milk is... Upon entering the living room, you fall silent at the sheer devastation of the room.
The living room is in a disastrous state. Once-elegant furniture and decorations are shredded beyond recognition. Everything within a 1-meter radius—Milk's reachable height—is in tatters.
