It’s like Frame-Arms Girl, but with a male Master…
Busou Shinki (“Armoured War Goddess”) follows a handful of “Shinki” under the care of a simple-minded yet incredibly appreciative and understanding Master who is rarely seen because he spends all day at school. “Busou Shinki” are one of a number of kinds of Shinki that exist, but they are most alike the Frame-Arms Girls of their name-sake Anime. They engage in combat against one another, and do their best to serve their Master when they’re not fighting.
Shinki are also not very tall. Like Frame-Arms Girls, they’re only about the size of a Figma figurine. The four Shinki starring in Busou Shinki are Ann, Ines, Lene, and new-recruit Hina (aka Strarf). Besides trying their best to make their Master happy, these Shinki have to face off against random challengers barging in on them. All the while, some random pet hamster sits around gnawing on a sunflower seed.
It’s good in all the ways Frame-Arms Girl was, and still different enough to make it interesting as well. Give it a watch!
