Retroactively known as the first season of the FLCL series, all episodes of the 2000 Japanese original video animation series were directed by Kazuya Tsurumaki and produced by the FLCL Production Committee, which included Gainax, Production I.G,[1] and Starchild Records.

[2] The English adaptation was licensed by Synch-Point,[3] [needs update] which released the DVDs and soundtrack.

[4] After Synch-Point went out of business, Funimation licensed and re-released the series on Blu-ray and DVD.

[5][6] The story follows Haruko Haruhara, a sociopathic alien drawn to the fictional Japanese suburb of Mabase by the Medical Meccanica building while weaseling in the lives of twelve-year-old Naota Nandaba in the first season and fourteen-year-old Hidomi Hibajiri in the second season as pawns in her agenda to acquire the being called Atomsk.

[14][15] The series was re-picked up for distribution by Funimation in 2010 and released again on DVD and on Blu-ray in February 2011.
