Inoue-sensei looked up as Hazō approached, and put the borrowed scroll of village philosophy down on the bench next to her.
Hazō glanced around, and then spoke to her very quietly. "Inoue-sensei, I'm worried about what Takahashi might be doing to Keiko behind closed doors. Maybe you should use Truth Lost in the Fog to question her about it?"
Inoue-sensei's eyes grew cold. "No. I'd only do it in the most desperate circumstances, if I thought he was doing something unacceptable, and I had to resort to questioning her to find out what, and she refused to tell me anything.
"Hazō, genjutsu users as a community don't have many rules, and some of them are more flexible than others, but arguably the most important one is that you do not use permanent mind-modifying genjutsu on friends, family or teammates without their consent, unless it's a matter of life and death. Even in a profession that violates people's minds for a living, it's considered incredibly morally wrong, and every single person who does it ends up as a deeply fucked-up individual incapable of normal human relationships.
"If they weren't one to begin with."
She stood up sharply.
"Excuse me. I need to go wash my hair."
I didn't expect there to be so many new systems.
If there is a thing only Madara can do, it is best to assume by default that in MfD he cannot do it. This will save you a lot of theorycrafting.
If I did have to model it with MfD rules, I'd say "gets a roll at all because Sharingan hax -> wins Taijutsu vs Weapons by a huge amount (would be screwed if he hadn't) -> Weapons to throw kunai back -> Taijutsu to do the rest".
While I love stunt rolls of various sorts in RPGs, MfD doesn't presently have a mechanic for them because a) players don't have fine-grained control over combat and b) you would die.
Could you clarify the conditions for this? Or do you mean a generic battle between the two?
As it happens, "Takahashi" is a very common Japanese surname. Typically, the kanji used are "high bridge" ("taka" from "takai" meaning "high or tall").
