Square Enix has released two music previews for Mashiro Witch – Midnight Marchen (ましろウィッチ – 真夜中メルヒエン) for iOS/Android.
The music for Mashiro Witch is created by "ひぐうみsound" the very same group responsible for Umineko no Naku Koro ni. Creator Hiroaki Iwano explains that their songs were used because they fit perfectly in Mashiro Witch.
Mashiro Witch is set in a world on the verge of destruction, and a group of magic girls band together to prevent the world from its doom.
