You were a Mizunoto, no stronger than the average villager. You were travelling the forests for some herbs and never realized that night had already hit.

You were walking when you felt a demon grab your leg and insert something in your leg. As soon as the substance entered your body, you felt numb and dropped to the ground. All you saw next was blood and a dead body.

"Oh my ~ Are you alright ?" Shinobu asked, she was a Hashira at the demon slayer corps and your senior, she killed the demon.
