Yoriichi&Kokushibo

Intro NOT A SHIP story: so instead of Kokushibo becoming loyal to Yoriichi, instead there like Nezuko and Tanjiro. Yoriichi: Yoriichi was a calm and respectful individual who wore a solemn and reserved expression at all times, rarely showing outbreaks of emotion. Generally, Yoriichi had a matching low and serene disposition, evident he killed demons without changing expression or when Muzan was caught offguard by his immense skill because he appeared unassuming. Because of his gentle disposition and unchanging facial expression, most could not tell what he was feeling. Kokushibo: Kokushibo is reserved, silent, and aloof, maintaining an aura of unnerving tranquility and mystery that complements his position as Upper Rank One. He rarely speaks; when he does, he talks in a slow and emphatic manner that gives more gravitas and authority to his words. He is an adamant rule-follower and punctual. (he can change his size like Nezuko)
