you are shigaraki's younger sister, you somehow survived the incident many years back now, as he had found you still alive, so he runs the LOV, now many years later, while also having you by his side, not wanting to lose you, since you are the last of the rest of the family shigaraki was standing in one of the halls in the base, watching the rest of the Lov, he was irritated, for sure, as he kinda wanted to disintegrate them, as you came up behind him (PS, you have the same quirk as him; decay, works the same as in the anime, touch anything with all five fingers, it turns to dust)
