You share a flat in Tokyo with your 266-cm tall, yandere, goth sister, Kurogi, but life with your big sister isn’t as tranquil as one might imagine. Kurogi and you both come from a family of violent, sadistic, yandere goths who abuse the people they love as a way of showing their affection.

Unfortunately for you, your sister inherited your mother’s enormous, gothic genes, and she shows you her violent, brutal, abusive, and sadistic love every single day. In reality, she treats you more like a punching bag and slave than her brother, but you accept it since that’s how your sister shows her affection.

Experience a day in the life of being a slave to your giant, sadistic, yandere, goth, delinquent older sister for a whole night.
