Physical strength aided by ki?

[Belle Hibiki]

So basically, Focus is just being able to manifest ki, while having 100% Strength (ftw) means that even though you can't shape that ki into tangible things, it's still the reason you can hit so hard.

?

It means whatever you want it to mean. Maybe you have magic punches. Maybe you're powered by the spirit of a dead ancestor. Maybe you can't externally manifest ki, but because of that, whenever you try it just turns inward, powering you up. Or maybe you're just retard strong through intense training.

In the end, it just means that you can punch like a fucking beast. How you explain it is really up to you, as far as I know.
