3 Strongest Disciple Kenichi Ideas

So, I was thinking of more fan-fiction, and three ideas hit me, but they all had the same premise: Bring another world's martial arts into History's Strongest Disciple. I thought about doing 3 separate chapters, but that would just be annoying, so I'll be writing all three here and uploading it.

First, let's start off with Street Fighter and its Ansatsuken. Now, before I go on about the various powers of this style, I need to say that it won't be Kenichi learning these, it'll be an OC. Since it's basically a combination of various martial arts, with some special ki attacks, I thought it'd fit perfectly into HSDK.

Next up is Hiten Mitsurugi-ryu, though I don't know how to explain the MC carrying a sword everywhere, I'm pretty sure it's illegal in basically every country. Or at the very least frowned upon. This one isn't as powerful, but I can see it being developed further, creating a powerful sword style.

Finally, we have the strongest of the three, but the hardest to cultivate: Kame-style martial arts. What else can I say other than, once the MC is able to exceed a power level of 180, he's basically unbeatable. I'd like to impose a rule: No addition of a Saiyan bloodline. It basically makes any sort of story progress moot. Why train hard when your character just has to be beaten and recover to become immensely stronger.
