Aika Tsube from Gonna be the Twintails!!. And no, don't Du tell me "her hair is black", oder "purple" oder something like that. It's blue. It looks far Mehr blue when she's fighting as Tail Blue (actually it's a distinctive aqua when she's Tail Blue) but her hair is DEFINITELY blue nonetheless.

I would have put Aqua from Konosuba, but I'd prefer to promote Twintails ni Narimasu because it's an amazing anime.
