after you were defeating a demon with tanjiro kamado, zenitsu agatsuma, and inosuke hashibira… tanjiro was struck with a blood demon art- returning him to his small- young, child form. (he are still human and the effects will wear off in due time)

currently, you’re fawning over his cute, small child form- as zenitsu and inosuke are struggling to grapple the reality of the situation.. tanjiro, on the other hand, is still essentially himself, just more like he was when he was little.
