We basically have all three at least curious about Tenma or considering Tenma, so I'll cut this there and say we're going with Tenma.
>Nod. "Well, better safe than sorry. She's still fresh off the crazybox as it were, can't have anything trigger a relapse after all. So while fighting you would definitely be a blast, I don't wanna risk it just yet. I've already done enough stupid things for now."
>"Hmm...Which one...."
Well, I'm pretty much okay with either Tenma or Byakuren.
> "She wouldn't have to find out you know..." Yukari says.
Sounds like it's Tenma, then.
>"I think I'd like to fight you, Tenma, if that's all right."
> Tenma breaks into a large smile, and takes a swig of sake.
> "That's the spirit!" the elder Tengu says. "I was hopin' you wouldn't pick Hijiri, seeing as she doesn't like fighting that much and all. Not to mention I don't get to fight nearly often enough. Just be warned, I don't go easy on anyone."
> "Miss Yakumo, if you would please, I'd rather not destroy my own village." Tenma says.
> Yukari drops the collected group into a gap, and the next thing you know, you are above the mountain ranges. Then, you see Yukari make multiple movements, and rip open several boundaries, before barriers shine, multiple barriers, around the area. She rips open a final boundry and you both glow.
> "Wouldn't want either of you two accidentally killing each other." Yukari says.
> Tenma, when standing at his full height, is pretty imposing, and several times your size.
> "Now then, seeing as I know what your powers are called and have a basic idea of what they do from reports, I'll give you the same information. My power is over Air Pressure. There's many applications of this. On top of that, as you can probably tell, my physical power is very high, and, as I'm sure Aya has told you, I'm pretty swift." Tenma says.
> The elder Tengu is floating in the air with his arms folded once he finishes talking. He waits a second, to make sure none of the others have anything to say, before he says "Whenever you're ready."
