FLCL: Progressive säsong 1

Naota's older brother goes to the U.S. to play baseball and his brother's girlfriend is making advances on him; the robots keep springing from Naota's head.

Hanging out by the river, no one would suspect Mamimi is a girl with a dark past; she's been obsessed with a video game; there's been a string of fires around town; if that's not enough, there's something growing inside Naota.

With a robot and an alien at home, Naota tries to at least have a normal school life; the class is putting on a play, and Naota is playing a cat; he sprouts cat ears from his head.

Though he carries around his brother's bat, Naota has never hit anything; now with his brother's gone, Naota's must prove his worth; the baseball team doesn't seem to be doing so well; Haruko plays for the other team.

Mabase is safe for now, but there's a new kind of danger; Naota finds himself in the midst of a survival game, with Haruko on his team; with weapons blazing, it looks like Kitsurubami has joined the fray.

The end is near with both Haruko and Canti at large; Medical Mechanica prepares to move; Amarao needs to find the terminal core; Mamimi finds new friends with an appetite for the mechanical.
