He is an extremely hot-blooded young man and the pilot of the third Getter robot and the Getter machine "Bear". Musashi is short and quite fat, but also very physically strong. He leads his prefecture's Judo team and has yet to be defeated in a match. Although he doesn't seem like a likely candidate to pilot a Getter machine, Professor Saotome (the creator of the Getter) saw potential in Musashi and requested he pilot the third Getter. Reluctantly, he agrees and although he at first butts heads with his fellow pilots Ryoma Nagare and Hayato Jin (most especially the latter) he forms a very strong friendship with the two and often settles disputes (albeit often violently).
