Hard to say… the only hint we are given are the names of two of his master’s techniques.
“Tsuyoshi-shiki Meisai” [Fortitude Camouflage]
“Tsuyoshi-shiki Ten'i” [Fortitude Transportation]
It seems that movement and stealth are the two foundations from which Chipp was taught.
That’s not to say everything else was something that was self-taught… far from it!
If anything, Chipp’s ‘evolving techniques’ such as Alpha Plus, or his ability to cling to walls and perform an Alpha Blade… or even his aerial Genrouzan… are all various stages of techniques that he learned from observing his master… and copying what he observed and continuing to grow and take things to the next logical step.
If he does deviate from his master’s techniques with one of his own, I’m sure his bravado will let everyone know! He’s not exactly the most quiet Ninja, and still hasn’t mastered the arts completely yet.
But, all that running around has to count for something!
