=== Season 1 ===
The first season of ''FLCL'' is a [[coming-of-age story]] and revolves around Naota Nandaba, a 12-year-old, working-class boy living with his widower father and grandfather. His life in the Japanese city of Mabase is interrupted by the arrival of a [[Vespa]]-riding maniac named Haruko Haruhara. She runs over Naota then revives him with CPR before hitting him on the head with her left-handed, [[Electric Bass guitar|electric bass guitar]] (a blue, vintage [[Rickenbacker 4001]]) and proceeds to stalk him. Finding Haruko weaseling her way into his life as a live-in maid, Naota discovers that the head injury she caused created an "N.O." portal, which [[giant robots]] produced by a company known as Medical Mechanica emerge from periodically. The first of these robots is hit on the head by Haruko and becomes a friendly service robot later named Canti. Canti ingests Naota to assume the reddened form he first had when fighting the robots sent after him.

Haruko claims she is an alien investigator from the Galactic Space Police Brotherhood, and her presence places Naota and those around him in danger. The Interstellar Immigration Bureau's Commander Amarao, whom Haruko has a history with, asserts rather that she is an apathetic seductress seeking a space-manipulating being called Atomsk who was partially contained within Canti. Every time Naota is absorbed by Canti, Atomsk is gradually brought to Earth. As Atomsk is held in Medical Mechanica's custody and Haruko ultimately places Earth under threat, the company eventually turns their factory stationed on the planet into a doomsday terraforming device, attempting to have Naota and Canti absorbed by the doomsday device's Terminal Core. Haruko's plan fails as Naota ends up becoming Atomsk's host and then releases him into the universe after a brief battle that ends Medical Mechanica's attack on Earth. Haruko follows after Atomsk, and Mabase returns to some normalcy.

=== ''Progressive'' ===
Haruko returns to Earth many years after her failed attempt to contain Atomsk in the first season, although she did manage to absorb him sometime in between these events. Placing herself as a middle school homeroom teacher, Haruko targets a 14-year-old girl named Hidomi Hibajiri through her classmate and eventual love interest Ko Ide. Haruko finds opposition in both the headphones Hidomi wears and Julia Jinyu, a more stoic offshoot of Haruko that splintered from her during her initial attempt to control Atomsk's power. Haruko eventually eats Julia to restore herself, and uses Ide to get to Hidomi. Like before, this causes conflict between Medical Mechanica and the Interstellar Immigration Bureau, as the latter was reverse-engineering Canti's technology to utilize the N.O. channel's energies for their own use. Atomsk appears on Earth as planned, but Haruko ends up failing again with a freed Julia taking her leave. Haruko regains her composure and is finally convinced to give up her obsession over Atomsk as completely unrequited, as Hidomi and Ide begin their relationship while Mabase rebuilds after much of it was destroyed by Medical Mechanica.

=== ''Alternative'' ===
Haruko enters the life of high school student Kana Koumoto and her friends as she became a mentor of sorts to Kana in helping the teen's transition into adulthood as Medical Mechanica begins its assault on Earth. While helping Kana resolve some issues as one of her friends leaves for Mars, Haruko ends up on another planet as a direct result of Kana's reverse N.O. portal that they used to transport Medical Mechanica's plants off the planet. The season takes place before the events of all the other seasons currently present.

=== ''Grunge'' ===
Haruko manipulates the mob-run town of Okura in a scheme to infect Medical Mechanica with a virus and steal Atomsk from them. In the process, she influences the lives of three working kids: Shinpachi, Shonari and Orinoko, before taking off after Atomsk on top of Medical Mechanica's plant. The season takes place between the events of ''Shoegaze'' and the first season.

=== ''Shoegaze'' ===
Masaki is a teenager who sees ghosts that nobody else can see, including a large ghost bird perched atop a tower. Harumi joins him in exploring the tower after it is locked down by the Bureau of Interstellar Immigration. Kana Koumoto (from the third season) is now a 27-year-old adult working for the bureau and is called in to assist in getting the teenagers out. After setting off an explosion, the teenagers find that the tower extends into N.O. space. The bureau chief admits that the purpose of the tower is to reconnect the dimension they are currently in with a separate one that split away 10 years ago and he hopes that with enough emotional turmoil he can get Masaki to trigger the N.O. device and merge them back together. After Harumi is shot and Masaki realizes that he loves her, his N.O. field begins the merger in which Harumi realizes that she is actually from the other dimension, a colony on Mars. As Masaki calms, the merger fails, and a large snake-like entity appears. In the closing credits, Masaki is able to jump dimensions through N.O. space to visit the Mars colony. He explains that the worm-creature helps him do so and its name is Atomsk.
