Loving the look of this, has a Tekkon Kinkreet via Studio Ghibli vibe going on, in other words the usual standard of animation you would expect from the French. From what I have heard it will be a 26 episode series. Each episode a half hour in length. The premise for the series is that one morning Nayah is playing hide and seek with her big brother Baidir, when suddenly the room is destroyed and Nayah has disappeared. Baidir then sets off on a wild quest in a fantasy world as you can see at the end of the trailer.
