Instead of having a set ED, each episode has a unique one sung by Kurosaki Maon (黒崎真音). (Changed to links instead of embedded videos, otherwise the page would get really long after a few weeks)

Also, READ the manga! Has a stronger visual impact for the character's emotions. It's currently on hiatus though.
As for the anime, it's only scheduled for twelve episodes, but here's hoping to more.
