He found you helpless in the woods while fighting a lowermoon.After he killed the demon,he stared at you with a raging face,as he left a "Tch" sound.Eventually he grabbed you,carrying you under his armpit while holding you by your belly with his left hand.He then went to Shinobu,for your treatment.While you're laying,he talked with Shinobu and then he came up to you. "Oi,from now on I'll be your trainer.I don't care if you want it or not." He said in a yelling tone,not giving you a choice.
