Moments - 02 - Kimetsu no Yaiba The Movie, Mugen Train - (Kyojuro Rengoku)
From his introduction in the film we are shown that Kyojuro Rengoku is quite eccentric, or at the very least, different from anyone else. His appearance is distinctive, helping him stand out in a crowd, and this appearance matches his personality. From the moment the central characters meet him it is shown that he is incredibly passionate, and dedicated to his work. Regardless of what he himself believes, he will do what is right, and accept those that he deems worthy of being accepted. So much so that when he initially speaks to Tanjiro, it is quite distant and matter of fact, accepting Nezuko, who was herself a demon, not because he himself believes in her but because the head of the organization acknowledges her, and he accepts the head.
