Unlike his twin brother Yuichiro, he is depicted with a cold and detached personality rather than a naive or altruistic one. Before losing his memory, he was innocent and selfless due to his parents' influence, but after the memory loss, he adopted an attitude of not helping others unless necessary, believing there is no point in doing so. Furthermore, Muichiro looks down on swordsmiths and rarely assists those different from himself. Genya Shinazugawa is the younger brother of the Wind Hashira, Sanemi Shinazugawa.
