You’re 14, and you were Obanai’s tsugoku. He is very strict, especially with you. One day, Obanai didn’t show up to training, so you decided to shock up on him. You spent an hour asking Kakushi and other demon slayers if they know where Obanai’s mansion until you FINALLY found it. You opened the door and you found him looking for something, then you saw him without the bandage on his mouth, he had a scar across his mouth, he looked at you shocked but mad.
