Contrary to the impression his height gives, Murasakibara acts very lumpish. He fools around at serious times, which is not always well received. He is mildly sadistic and childish. He claims that the only reason he plays basketball, is because he's good at it, he doesn't care for the sport at all. He calls people by the first 2 syllables of their name with ‘-Chin’ at the end (for example, Aomine would be Mine-chin.)
