It said limitless in the same sentence that it said that his physical form would explode into gorey bits if he did go limitless mode. So...uh...yeah, he dies when he goes over 9000. Yay.

That being said, that whole thing about 'selecting the headmaster as his opponent in every fight' is probably something that could be done, but he doesn't do that, because Arata wants to have a fun, hard-fought fight. It's a self-inflicted curse for a reason.

Of course, there's people who ignore personality in favor of winning, but I generally try to avoid doing that.

But if this non-destructive magic is something that effects him or his presence or whatever...why wouldn't he be able to resist it? Still not really understanding what you're getting at here, so clarification might be needed on this subject matter after all. I've never read or watched Trinity Seven, but a quick scan from the wiki showed that the Arata over there can only dispel the magic of those that are magically weaker than him in exchange for being able to dispel literally everything, while Legendary Resistance only works against non-damaging effects, in exchange for allowing him to ignore such effects without having any magical knowledge of his own.

So yeah, could you elaborate on which situations regarding non-destructive magical effects would bypass Legendary Resistance?

Say this.

He can and will shrug off things that are not meant to destroy him. That much is cool with me. Can't be destroyed unless the magic is meant to do exactly that. 

Telporting him elsewhere doesn't work either, okay, I get that. However, what happens when your entire existance is erased from times? 

Liselotte Sherlock is able to use this kind of magic in Trinity Seven, at the cost of being locked away in time herself. Her whole presence and being is transported there. Edgar's is slightly different, though, as you can see from Vocab's explanations. 

What I mean to say is that the Arata of Trinity Seven can too dispel anything thrown his way, though he does need to shoot it at the very least, yet finds himself trapped in this sudden time lock. Because you are being transported outside the axis of time, an imaginary concept created by humans. Arata may not understand this, but I guess that he would indeed be affected (correct me if I'm wrong)

Then, another kind of non destructive magic that I think would work against him is putting him inside a pocket dimension, or a reality marble. Doing something like such is not destructive and will simply transport him elsewhere. If the portal to these were open and someone were to push him inside, would he be able to resist that too? 

In any case, there are some questions better asked when they pop up IC-ly, so let's wait and drop the subject for now.
