Akio is a young boy being raised and trained by his legendary martial arts master Panchi, and he has a dream: to someday be one of the legendary warriors known as a "Fist Master", whose powers and abilities supposedly far surpass mortal limits. There are just a few issues that might get in the way, however: first, Akio doesn't want to actually hurt anyone and doesn't have an ounce of maliciousness in him, and second, Panchi is a jaded jerkass who doesn't think much of Akio's dream or his potential as a martial artist, especially compared with Panchi's teen daughter Red, the group's voice of reason who is a promising martial artist and has quickly mastered a number of techniques including how to utilize her ki, something Akio has totally failed to do as of the start of the series. Still, nothing can shake Akio's determination to be a Fist Master and as he undergoes Panchi's grueling training and interacts more with the various powerful fighters around him, he might get a chance to see if he has what it takes... if he survives the experience.
