If you are going to evolve Kubfu in Rapid Strike Style Urshifu I suggest the the technique of Seikūken from “Kenichi: The Mightiest Disciple” since it can be useful for a fighter who has its qualities. I don’t know how to implement since our protagonist doesn’t have memory of his past life, but this is something I suggest. At most this technique will be something he self taught during his six years of school or something he supposed but didn’t put on practice since this is a high level technique he isn’t sure to learn it by himself.
