[@Krot] Doesn't really explain why he's immune to illusions tbh. I'm being picky on this because so many have taken immunity to genjutsu for granted in the past. Though the weakness does balance it out, it essentially makes you dominate most genjutsu specialists. And yes, a kunai bomb suffices to rip you up, but I'm mostly asking for a reason as to why it gives immunity to illusions. If anything, I'd assume something as intangible as illusions would be one of the biggest things to counter immaterial people. 

I'm mostly asking for reasoning here, not an outright denial.
