Like Maeda's other hentai series (e.g., Urotsukidōji), La Blue Girl features a large amount of tentacle rape.

However, when thieves steal the magic compact that grants the clan this power, Miko has to fight the Shikima, utilizing her "sexcraft" ninjutsu in order to save the world.

Shin Injū Gakuen / New La Blue Girl (two episodes, 1993) adapts the end of the manga, and as such is a follow-up and the conclusion to Miko's adventures in the first series.

Features an original story about two ghosts, Kyoshiro and Shanahime, harboring an old grudge against the Shikima and attacking several of Miko's friends, including her first love.

The flutes are now cursed and Miko's dream guy, Hidemasa, is kidnapped by the vengeful phantom of Shanahime in order to resurrect her Kyoshiro.

La Blue Girl Returns (four episodes, 2001) is an anime series that continues the adventures of Miko Mido.

Another original story, this time about the legendary Shikima Brain, a place rumored to bring total power over the universe.

The plot begins when a race of butterfly-like demons named the Mahoroba want to enslave Miko Mido and her sister to steal the seal case that controls the Shikima.
