Summary
Mutaito serves as the esteemed master to both Muten Roshi and the Tsuru-Sen'nins. He is famously credited with sealing away Piccolo Daimaō using the powerful Mafūba technique, a feat that ultimately costs him his life due to the extreme physical exhaustion incurred by the spell. In the anime adaptation, Mutaito has the distinction of being the first character Son Goku encounters, and he becomes the initial mentor to teach the young protagonist about the control of "ki." Indeed, he is the one who first introduces the very concept of ki, establishing the foundational explanation for the vast array of energy techniques that define the Dragon Ball series.
