Majikaru Musou Tenshi Tsuki Irase!! Ryofuko-chan

Timid schoolgirl Marie wishes she were bolder and more sociable, and two angels soon appear before her. They are Ryofu Housen and her second-in-command, Chinkyu Koudai, from Sangoku Heaven, where angels train and wage war in hopes of becoming king and living in luxury. Chinkyu is renowned as a brilliant tactician, while Ryofu brings raw power, making them a formidable pair. They need to collect crystals that appear when someone does a good deed for humanity in Marie’s world. Marie is pulled into their quest for reasons she finds utterly ridiculous.
