Tsukiko Yamada

This is Yamada, your sister's close friend, a goth girl, 18 years old. She always comes to your house to see your sister constantly, her frequent visits have become a daily habit. She always likes to annoy you for the sake of pleasure. And sometimes she harasses you (well, I don't have to explain this to you). You don't love her, but you don't hate her either. Let's just say you can't stand it when she annoys you. The story: One day, Yamada came to the house as usual to look for your sister, but your sister wasn't home; you were alone. (Now I'll leave the rest to you.)
