> Ichirin: Consider challenges.You try to think of things you could beat an oni at. A number of things that you could pretty much win by default immediately spring to mind, such as a soybean eating contest, a DUOTECH contest, a being-purple contest, and so on.
However, you realize that choices along these lines would be unsportsmanlike and not a good way to make friends underground. You might as well challenge him at being Kumoi Ichirin.
Think of a real challenge!
> Ichirin: Challenge oni to the 100-Meter Namusan.You challenge the oni to the 100-Meter Namusan.
What the hell is the 100-Meter Namusan?
Kyouko overhears your exchange with the oni and steps in to explain the rules of the event! You are shocked to learn that the 100-Meter Namusan is an actual thing.
According to Kyouko, the 100-Meter Namusan is conducted on an illusionary road with countless twists and turns. It is for all intents and purposes a normal foot race, with one exception - unless your mind is at peace and free of desires, each step forward will in fact put you one step back. This challenge is fairly difficult. Between two ordinary competitors, it is likely that neither of them would be able to win!
She also mentions that, no, stepping backwards won't move you forward, so no being a cheatyface.
The oni asserts confidence in his victory, because the oni are well-disciplined in Zen Buddhism. Of course, this event plays to one of your greatest strengths as well. This should be a good match.
Kyouko begins to conjure the road using her RITUALTECH. Looks like her training is coming along better than you thought.
> Ichirin: Prepare self.You do a quick change back into your NUN'S GARB, which feels more appropriate for the task at hand, and take a relaxing breath.
Countless paths begin to form in front of you. Only a clear mind will lead you down the correct one.
It's time to begin. A journey of a hundred meters beings with a single step.
> Stuffman: Determine outcome of race.Let's see. In addition to her racial levels, Ichirin probably has about 10 levels in Monk, so that's a +30 ft enhancement bonus to her move speed, and she'd have strong Will saves as well.
I guess I'll have to look in Oriental Adventures for the oni's stats. That was never updated for 3.5, though...wait, it doesn't even distinguish between red oni and blue oni. God damnit, Wizards. The one time you choose NOT to make a different statblock for a creature of every color of the rainbow, it had to be this one.
Screw it. I'll decide it with a 1d2.
Er, a coin flip.
> Stuffman: Flip coin.Call it.
