I hope she's not attacking by herself. She's only a Stage 6 boss, whereas Flan is an Ex Boss.

that's one hell of a crossover

mixing Touhou with Ace Combat was great enough already
but to add here Battleships from Last Exile
it's just too awesome

Considering we've seen single pilots do crazier things... I think she might be okay.

I don't get where Ace Combat comes in, unless Utsuho's supposed to be an X-49...

Stages aren't everything. I mean, Yuugi's only a Stage 3 boss, and it's not as if she's in the lower half of Gensokyo power-wise.

Its tagged TOHO☆COMBAT.
Other images with that tag by him have shown Ace Combat Style HUDs on screen Such as this one

Probably the intro to the Enemy Superweapon destruction Mission.

Edit: Thanks for the info OOZ662

Danbooru uses an awkward way of linking. Put the words you want to appear in full quotes, then a colon, then the URL with no spaces.
'Such as this one':post #726274 with quotes instead of apostrophes would link.
Alternatively, posts on Danbooru and its mirrors will autolink when you plainly type, for example, post #726274. The benefit being clickers will stay on their domain instead of being transferred to the one you use.
