My biggest issue is with Haruka - she's a boring, indifferent, empty shell of a person. She's this way of course because the show is based off of an otome, and she's supposed to be this way in order for the player to better "insert" themselves in her place, but good god - give the girl a damn personality!!
Now don't get me wrong - she's much better than some. She wasn't nearly as bad as Nazuka
