High schooler Mizuhara Ryou lived alone with his little sister Akane ... until the day she arrived. Parachuted through his window, to be exact.

A crash and flying glass heralded the girl who was to change his life forever — her name was Shizuka, and she was his fiancee, sanctioned by the Japanese government (backed up by a whole lot of men in sunglasses and black suits).

Now, every day, he is subdued (physically and mentally) into accepting Shizuka as part of his life ... never mind that he might possibly harbor ambitions of his own! This anime is based on a visual novel of the same name. Each episode is a little bit short — only abut 15 minutes long.
