A burned-out knight finally buys peace, then a witch crashes through his roof and somehow makes retirement the funniest thing that could happen to him. The chemistry between them is immediate and earned, not forced, they bait each other like people who've known each other for years. Ten minutes is barely enough to breathe, but that's exactly the point: this OVA knows exactly what it wants to be and refuses to overstay it.

Astra Ludger Doomsday, once captain of the royal knights, has at last reached the goal he wanted most: stepping down and spending his savings on a home of his own. He has barely settled into his new refuge when a young girl comes crashing into the house. She turns out to be a witch in training, and she appears to think Astra is somebody else. The result is a short fantasy action comedy OVA adapted from a manga by Narita Imomushi and paid for through a crowdfunding campaign.
