Life seems to drift by for Kana Koumoto and her friends in their small Japanese town. Every day is just like the last, and it feels like every new day will be the same. Kana goes to school, hangs out with her friends, and likes to paint her nails and listen to music, but it feels like nothing special is ever going to happen. As a change of pace, Kana and her friends decide to design a bottle rocket and launch it into space, even though it might not get there at all. However, just when the rocket is completed, a robot suddenly crashes into and destroys it, shortly followed by a pink-haired woman claiming to be a "Galactic Investigator." Kana's life quickly becomes more exciting than she ever imagined, dealing with new feelings, changing friends, and even boy troubles. It turns out life can go by in the blink of an eye, fast enough to even miss it, so what's with these weird robots that seem to show up at the worst times?! [Written by MAL Rewrite]

Hidomi Hibajiri is a dissilusioned young girl who never takes off her headphones. Her whole life consists of going to school, helping out at her mother's cafe, and listening to music. And with nothing else to break the crippling monotony, she keeps her headphones on at all times. That is, until she is run over by a mysterious guitar-wielding woman. That same night, a robot barges into Hidomi’s room along with a boy from her class, Ko Ide, and the kids are chased around town together. They're saved by the guitar-wielding woman from before, but now Hidomi's got a horn growing from her forehead? Who knows where these robots are coming from, what kind of vespa woman this weird guitar woman is warning her about, or what this thing on her forehead is, but it doesn't look like Hidomi is going to be able to ignore all this with headphones!
