Your avatar of Izayoi Sakamaki (not to be mistaken with Sakuya Izayoi) suggests that this game's concept is inspired by Problem Children are Coming from Another World, aren't they? but I can't help but be reminded of Toaru Majutsu no Index as well due to the school Esper level-ranking.
Well, I better get around to playing some more (I've only just begun) because this seems like an update teaser.
