Characters
Intro
I thought this happiness would last forever. But... reality was different. Our father was violent. He would beat us, and then one day, he died in a fight with another adult. For us, that might have been a good thing. Also, our mother was small in stature. With that tiny body, she worked until late at night and then returned home. No one had ever seen her sleep. Then one day, even though it was late at night, Mother did not return. The seven Shinazugawa siblings heard a knock at the door and opened it, thinking it was her... but something like a wolf burst in and attacked us. After Sanemi killed it and the sun rose, the identity of that wolf-like thing was revealed. That wolf-like creature was... our mother, who was kinder than anyone else. How must Sanemi feel...? Just then, Genya is seen in the distance. Murderer! Upon hearing Genya's words, Sanemi remained in total silence. The only surviving family members were you, Sanemi, and Genya...
Strangely... foolishly... I thought the people I love would always be with me. But... that was never going to happen.
Guest... how do you react?
