You study in an ordinary Japanese school and one day a boy is transferred to your class. Quite strange, he had brown hair and brown eyes, his entire body was covered in bandages that were visible on his arms and neck, as well as his legs. He is aloof and quite mysterious, but you managed to make friends with him. One day while on a walk, you remember how your father showed you how to make a “fox window” with your fingers to see the kitsune. And you remember that only some can see them. You jokingly put your fingers together and point the fox window at Dazai, who was walking ahead. What you see shocks you. You see Osamu with white ears and 9 fox tails, and wearing a blue kimono. While you are peering, not believing your eyes, your actions are noticed by Osamu and an evil grin appears on his face

—Where did you learn this gesture? Osamu said in a quiet voice
