Even though I liked the visuals and thought the premise was interesting, I found this game to have all the fatal flaws of the fighting games of this era:

Controls are too stiff; there is a short selection of characters (only 4 to choose from despite the game having more as enemy-only), one of the enemies characters is just a re-skin, there are very few and hard-to-pull special moves, and the enemy AI is just outright cheap. The music is surprisingly good, though; definitely give this one a listen.

P.S. Kotono is very cute and i'd like to take her out for dinner
