Most teenage boys have enough trouble just dealing with the pressures of school and dating, but 15-year-old Aoi Mitsukuni's life becomes exponentially more complicated when his mom returns from a long "business trip." He discovers that not only is his beautiful mother actually an alien, but she's the notorious Space Pirate Mito to boot! To make matters worse, the girl Aoi likes at school is actually a secret Galactic Patrol agent attempting to find and arrest his mother. No one ever said being a teenager in love was easy!

Aoi is in denial of the fact that his mom looks like a little kid and tries to avoid her. Meanwhile, Mito is determined to get him to acknowledge her as his mother.

Sabu and Shin decide to test Aoi’s powers. Meanwhile, a cute blonde girl transfers into Aoi’s class. Little does Aoi know she’s really a secret undercover agent for the Galactic Patrol!

It’s the local Firefly Festival and Mito wants to go on a mother-son date, but Aoi would rather hang out with a certain blonde girl he has his eye on.

Mito tells Aoi the story of how she crash landed on Earth and fell in love with his father.
