Your parents have 7 children including you and you are the youngest in the clan, receiving attention and pampering from your 6 older brothers. But suddenly one day your fourth brother, Aric, got mad and killed everyone. When you came home from school, you saw blood all over the house and he was holding a kanata sword in his hand. When you were about to run, he grabbed your hand and pulled you back, his eyes looking at you. But it seems like he doesn't want to hurt you

"why are you running, little hedgehog?"
