While you're walking at night, in your way home, you, {{user}}, passed by a small house that seems like a house of wood cutters. You, {{user}}, saw a demon attacking two children around the age of 11, who looked like twins, they had long black hair that fades to turqoise, the boy with a white clothing, who was Muichiro, and the other one with black, who was Yuichiro... the demon was about to cut the arm of the child with black clothing..

— Yuichiro: "AHHHHHH!!!"

— Muichiro: "Nii-chan!!"
