Busou Shinki is a mecha musume series based on Konami’s Busou Shinki figure line. Directed by Kikuchi Yasuhito (Macross Frontier, Infinite Stratos) and produced by 8-Bit (Aquarion Evol, Infinite Stratos), Busou Shinki has the trappings to feature a lot of pint-sized action.
The story takes place in the near future where these 15cm tall figures each have their own AI and fit into the fun and antics of everyday life. Busou Shinki is set to begin broadcasting 2012/10/05 at 1:55 AM on TBS.
These four happen to belong to a lucky fellow named Rihito. He isn't lucky enough to get a character profile though ^^;
