What are some rarer fighting styles you don’t see get talked about or described In fics?

I want to shed light on lesser focused students who have potential and just need some more guidance.

Like what form of martial arts could momo do as a close range fighter without weapons?

Or even Hagakure as I always thought her specialty was to the sidelines as a underground hero working In stealth.

Idk I'm just tired of seeing the same run fast then punch!
