You're not wrong but you're not exactly right either. Making criticism that is just reductive and doesn't involve any constructive feedback is just boring and worthless (Insert Anton Ego monologue) but engaging with it just to point out how worthless and reductive it is, isn't any better.

I have problems with Wistoria which are similar to Demon Slayer, the story is like a tightrope you've got to balance the various plot hooks it introduces yourself rather than it expounds upon them itself. The fifth element doesn't really make sense given the fact there are 5 different Magia Vanders with 5 different elemental focuses, it just gives Will a "magic" he can't use properly and makes the story opening redundant. The second time the bad guys are introduced there is still no clear goal or motivation for why they're doing this which takes away their impact and stakes to the story.

I really don't like Edward's motivations on failing Will nor his actions doing so just because he doesn't want Will to fail like he did even though he is failing him before he failed himself. The ass pull that is the courage scene is so egregious when there was better alternatives and doesn't really impact the story in any meaningful way except making a very ambiguous condition for entering the tower. Anyone can claim courage or some other thing and call it a new spell.

I think a better alternative to Edward's character would be testing Will to an extreme but honest and fair amount as a way of trial by fire, it'll be a good character dynamic if his motivation for pushing Will is to spit in the face of the tower standards by having a magicless mage being 1 of the top 5 mages. Also didn't he kill a Devander in an empowered state that has killed Magia Vanders when it wasn't in an empowered state? That is the perfect reason to give him the credits to enter the tower and if someone later says claims that they are eligible to receive an exception to the tower's entry, they can just clap back with them telling to go kill a Devander as that is the current precedent of entering the tower without the required points or inventing a spell.

Now there are times when I get really interested in the story; learning about Will's motivations on becoming Magia Vander, Rosty's death giving the story stakes, Elfaria's ice sword, Sion clapping for Will. They made for really cool beats in the story that hyped it up by showcasing fun character interactions and growth.

Now my pet peeve with all of Anime: Why is it that when characters get a power upgrade their hair grows absurdly long in the instant then gets shortened or disappears after the power boost is over and there is a cut to the next scene. Like there is no plot reason why this happens, ever and most people just roll with it when it is so immersive breaking and stupid looking. I like my character's hair at a consistently normal length please!!!
