[@Pandapaw23] That's a fair enough assessment. I will say that even a fighting series does sometimes have large exposition dumps... though in this case, it's really just me making sure every base is covered, so that everyone is clear on what Seirei can do, and failing to be concise in the process.

I'm not going to lie, though, folks. One of my primary concerns was with whether the power is too strong or not, at least compared to the abilities displayed by other characters so far. If I could get some opinions on that, I'd greatly appreciate it.

Yes. Quite excepting that his IES apparently makes him Fate/ Lancelot and 'instinctively a better wielder of any weapon than anyone at the school could be' (seeing as nobody here has had decades of practice) seems like an odd choice for 'magical ability'...

The AED's actual abilities seem to work out as:
1) Super sharp cut
2) Ignore being blocked
3) Super speed/strength/toughness
4) "That wasn't the real me you hit at all!" + teleportation
5) "Attacks from all directions simultaneously"
6) Everything is blurry because of the justification for all this, making it a pain in the ass without the boatload of special techniques.

That's [i]way[/i] too many things going on at once, and the power justifying it feels like a cheap excuse afterwards. It can create intangible overlapping clones that take no damage... oh but they can clearly be tangible when it's convenient, i.e. purely for the sake of attacking? That's not clever ability use, that's tailor-making an ability to justify being as strong as possible.
