Accompanied by a voice that was young but carried a hint of sunshine.“It's okay, I'm here. Big brother is here to protect you.”The boy with purple hair and purple eyes held a scythe in his hand, blocking in front of the girl, and issued a declaration of death to the old man.“You deserve to die, Zouken Matou. No, Makiri Zolgen!”
