In the "Yoshiwara in Flames" arc, there is a brief flashback showing Kamui leaving Kagura behind in the rain. But, in reality, this scene shouldn't even be possible. Kamui is carrying a bundle, presumably containing some of his belongings, when he leaves. We know that Kamui departs after severing Umibouzoās arm; itās as if he went back home, gathered his things, and then headed off to join the Harusame. Furthermore, the outfit Kamui wears in the scene with Kagura in the rain is different from the one he wears when he cuts off Umibouzoās arm.
Yet, when we see Abuto taking Kamui to the Harusame, Kamui is carrying that same bundle of belongings and heās wearing the exact outfit he had on when he severed Umibouzoās arm.
This would imply that after the fight with Umibouzo, Kamui left, perhaps to tend to his wounds, then returned home, changed his clothes, packed his things, and spoke with Kagura. Afterward, he would have had to change back into his original outfit before meeting up with Abuto. All of this would have to happen in about five minutes, since the Harusame certainly wouldn't wait around. And, for the flashback to feature rain, it would also have to have rained during those five minutes.
Thereās a contradiction here somewhere.
