Here's the info according to the source:
- Being produced by BeeTV
- 19 episodes long
- Voice actors Chika Anzai and Wataru Hatano
- Theme song by Tsuchiya Anna
So it's not an anime as much as a video adaptation of the manga! Voiceovers, sound effects, some animations, and a reaaaally lovely opening sequence!
