Might be interested, just a few questions regarding techniques:

We start with "four points", how do these work? Is it four techniques only, can we spread them at will across techniques so we could have a lone 4 point one that's much stronger than a one-point one? Same on the whole Health-Skill-Focus thing. What do these do, what's the difference between skill and focus, what's the point of these?

It feels as though you're trying to have some sort of system to limit things and introduce progression without actually detailing it or making much of a system at all and that just kind of muddles things. Also, as a minor nitpick, what you classed as "stats" feels more like "skills and abilities" or somesuch.

EDIT: Also, where would we be starting at power-wise? Would haki be a thing? Are logias allowed? Legendary zoans? Canon fruits?
