Planet Guardian
プラネットガーディアン
Koyuki is a middle school student who considers herself timid. Despite her reluctance, she is destined to battle hostile extraterrestrials and return them to a cosmic detention facility. She receives support from her brother, an enthusiast of magical girl anime, and Pyrosuke, her mentor. The manga has a comedic tone, distinguishing itself from typical magical girl stories by being based on a role-playing video game.
