Yeah, that's some wankery to Happosai, right there. He's not as strong as Hayate. He's not even
nearly as strong as Hayate. He's a High Tier Master. They make other Masters (like Ranma) look like trash. But Hayate could school the rest of Ryozanpaku without even trying. He would do to Happosai what Happosai does to everyone else. He would do that to
five Happosai.
Uh where does it say that there is a Masquerade? Cause I kind of missed that.
What, you didn't read the issue where Kenichi is told by his masters that he must carefully conceal his skill from the mundane world. or else they'll snap his wand and expel him from Hogwarts?
Cute. The extreme martial artists don't exactly
hide as much as they don't advertise their presence at all. And the government covers for them. Confirmed fact.
Furthermore, it was stated that Black Sun wants to take over the world using martial arts because they think the ability to rip tanks in half with their bare hands and/or a kitchen knife makes them better than anyone else (and it's an admittedly compelling argument), and that not advertising the fact that they exist is a stupid idea, when they could instead do so and rule the world.
