* EnsembleDarkhorse: Alice. Has one episode dedicated ''solely to her''.
* HarsherInHindsight: The story revolves around the backwater island of Shimojijima housing a Meteor Sweeper intercept squadron, which is ostensibly an air force base specifically designed for meteor interception. Lately (as in 201３ onwards), there has been [[http://jsw.newpacificinstitute.org/?p=10691 talks of transforming the real life civilian airport that is the base for the Shimojijima base in the anime to a Japan Air Self-Defense Force base]] due to increasing tensions with Japan's neighbors. Obviously, the locals aren't really pleased about the possibility of housing JASDF in their home island. Only time will tell if this will become true.
* LesYay: Apparently. [[spoiler: It's how TheVirus is transmitted]].
* NightmareFuel: Somewhere past mid-season of Season 1, especially where [[spoiler:Karin tries to infect Mikaze.]]
* SurprisinglyImprovedSequel: Some fans argue that the ''Advance'' series are better than the original.
