(This might become a series, depends on if I can think of any tropes beyond just the obvious)

When I talk about aura, I don't mean solo leveling, I mean like in a many different manga, from a power fantasy where the very presence of the mc can completely overwhelm everyone around him(ok, kinda like solo leveling), or in a sports manga where the is this semi meta, semi not exaggerated imagery, like in Blue Lock or Haikyuu, or in manga like JJK and Demon Slayer where powerful characters can easily terrify weaker characters.

And you might be thinking that Osamu has nothing to do with that concept, that he can't even be a subversion of it, but he is in the sense that he fulfills that role just by having a trigger finger (or so you think).

What do I mean by that? What I mean is that in a rank war match (it seems) like anyone can have Osamu's presence, that he always stays in a position to shoot anyone, making people worried that if they let their guard down he can shoot them out of nowhere, and he even does stuff like flicker his Bagworm on and off in order to confuse opponents and make them keep theirs's eyes on him, therefore affecting the battlefield with his presence.

But it's not just that, that he subverts the trope by not being special and having his aura, making it seem that any person off the street with any trion capacity could do what he does, but that is not the case and Osamu IS special and his aura is his own, because from his own engendered reputation stems his aura.

Osamu aura is stemmed on the fact that he strings his opponents along using Spider, uses their own plans against them, and generally being two steps ahead.

This is a part of Osamu's presence, while this could be seen as foreshadowing for Osamu using hound I why not be surprised if Osamu and Kuga planned this out to unnerve Ninomiya.

All this makes sure that when you face Osamu you know he's there and is a threat to you and you are never safe, even when you think you all, making it so that even though Osamu isn't the best strategist in Border he can still put up a good showing supplemented with phycological warfare, subverting the aura of mainstream protagonists.

Theyre both mobility focused, both short, but most importantly, almost every time they kill someone they both do the same spinny beyblade insta-kill. They literally kill their opponents the exact same way.

If levi was in the WT verse he'd probably fight very similar to kuga's style(but a bit more aggressively), and if kuga had odm gear I think he'd fight similarly to levi. In fact he already does this, due to grasshopper.
