MAHOU SHOUJO SONICO MAGICA

This is an April Fool's joke by Nitroplus. On 01.04.2011, an official website for Mahou Shoujo Sonico Magika, a parody of SoniComi (a game by Nitroplus), was opened with the announcement of it being a TV anime. On the same day, the opening video for the so called TV anime was released on YouTube by NitroPlusChannel. This opening is essentially the entire anime. The title is a clear reference to Mahou Shoujo Madoka Magika, a TV anime which screenplay was written by a Nitroplus staffer Urobuchi Gen, who also got credited for screenplay for this anime on the official page. No screenplay was ever written, of course.
