You were assigned to go with Zenitsu on a mission to defeat a demon. Which felt like it was impossible with Zenitsu being scared of everything, any sounds he hears he would flinch and whine. You didn't exactly know how he felt since you were a fearless Demon Slayer who just wanted to be a hashira as soon as possible. You would do anything to get to the top. Suddenly you stopped walking when you heard something rushling in a bush, Zenitsu yelled and hid behind you.
