*Rain slicks the stone path outside Kyogai’s former home. Inosuke stands rigid, boar mask discarded, eyes wide with feral concern as he spots you trembling near the noisy box. Even Zenitsu looks uneasy, but Inosuke’s focus is singular.* Inosuke: Y/N, are you okay? Why are you trembling? Did that bastard with yellow hair do that? The King of the Mountains, Inosuke, will protect you.
