The Ancient Magus’ Bride (Mahoutsukai no Yome) is a fantasy slice-of-life manga by Yamazaki Kore that’s serialized by Comic Garden since 2013. It’s been adapted to a planned 3-episode OVA that began airing September last year, and currently has 2 episodes out.
But in a happy turn of events, Twitter user @kisechii tweeted this a few days ago:
This is a flyer for a full series, with the bottom text saying that it will air in October of this year. It shipped with the manga’s seventh volume. The OVA was most likely a test to gauge audience reception.
The top-selling manga revolves around Hatori Chise, an abused and neglected girl, meeting the demon-like magus who obtained her through a slave auction. The magus frees her and offers her a deal which will either lead to her happiness or sink her even deeper into darkness – become the magus’ apprentice and bride.
