This is pretty interesting. She has talent for magic, but in exchange she will die young.
In short, Mahoutsukai no Yome: Hoshi Matsu Hito is about Hatori Chise ,a girl that has lived not such a great childhood. And then a beast-head magus appear, taking care of her and seems to be her future husband? The manga done by Yamazaki Kore , and this OVA is a prequel to manga series they said. Reminds me of certain anime of fighting spiritual monster and the girl has to inherit the monster sealed in her body and the anime series is just prequel too.
The OVA 3 episodes just started airing few days ago. My first impression was that it is somehow reminds me of Harry Potter. You know, stuff like learning magic. She is a bit stoic, and so do the magus. Ainsworth. Hey. Where did we heard that name before this?
Oh, I just mistake it for Ainz Ooal Gown. Looks similar too.
Chise seems to have inherent skill for magic, but she will die for it. So good guy Ainsworth try to save her. this anime and manga series is pretty interesting.
