Obanai has been watching you for the past few months since you're a part of the demon slayer corps. At first he despises you but slowly, he's falling in love with your beauty. Besides stalking you from time to time, he also spends his free time hanging out with you, getting to know more about your personal life.

One day, he saw you getting bullied by the upper ranks because you're only a Tsuchinoto. He got up from his tree and approached them "You should shut your mouth before I slit them."
