And if the antimagic was actually supposed to be useful for fighting us it would've been a toggleable aura.
Um, how does "toggleable aura" anti-magic differ from the anti-magic that Kirika has? Kirika has area effect anti-magic that can exclude allies from its effects and activates on command.
The anti-magic Kirika had was pretty useful for fighting us. It is quite literally the only reason that there
was a fight. It vaped Mami's ribbons that were binding them and took away our grief control and forced us to fight hand-to-hand. Yeah, Homura still had her gun (although she probably couldn't have pulled any more guns out of her shield), but before she was anti-magicked she had her gun
and timestop and could have just instantly blown them both away.
And, none of this even matters, because the argument in question clicks in so nicely alongside what we've already said. It's a matter of "oh, this is a credible alternative theory that I can't discount," not "but can you prove that."
So you're saying that it doesn't matter if it's true, just if it gets her to doubt her assumptions? That's valid, I suppose. But my concern is that that she
will discount it based on the issues I've raised, and it will make her start to doubt the validity of any other points we've raised.
There is another canon meguca with far more powerful mind control.
Kagari Hinata - Puella Magi Wiki
Look her up. She's ridiculous.
Oh, right. I never did finish reading Suzune Magica.
Reading that wiki article, it seems like she can't actually turn someone into a mindslave, just fuck with their memories and perceptions. Perception alteration could screw with us pretty bad, but memory alteration wouldn't work on us because the player base would spot the discrepancies. Of course, there might be other meguca out there who can totally cast Dominate Person. But would that make for an interesting quest?
The important point to make here is that Kirika did not wish to help Oriko against her enemies, she wished to help Oriko.
To help Oriko, so that Oriko would "never have to stop." Other meguca are the ones most likely to stop her.
The definition feature of Oriko as a magical girl, is how much her powers fuck with her. This is part of why Kirika manifested anti-magic, rather than any of the other options that could have helped just as much when dealing with other magical girls.
Her anti-magic was helpful for reducing Oriko's pain when her powers were on the fritz, but that seems really thin to me.
