If its just "but Kojirou's famous for TG and Shuwen is famous for NSS, why not NP" then, well, you have the skill tree idea is that they're an embodiment or expression of a style of combat rather than an anecdote given form. NPs are replications of myth given form.
It sorta ties into the fact that Kojirou isn't Kojirou, yet knows the real thing's technique. This is in contrast to Herk's Nine Lives or Cu's thrown Gae Bolg, which are also techniques, but unique to them. NSS is the core concept of a martial art, so, allocate all your skill points there and you can do it maybe. Allocate all your skill points to spearfighting or lazor dragon bows and you won't Gae Bolg or Nine Lives.
Basically, TG or NSS is that case in a D&D game where, to get the feat whirlwind attack you have to first get a bunch of other feats first to qualify. Nine Lives or Gae Bolg isn't something on the sheet, though, but that one time when you cheesed the system and shot brilliant energy shots from your bow and rolled nat 20 three times in a row and then you used a Wish spell to be able to repeat that feat once per day as your signature move because fuck the DM, you're motherfucking Herakles.
