La Blue Girl (four episodes, 1992–93) is an adaptation of the original manga. 18-year-old ninja in training Midou Miko is entrusted with the family business: making sure that sex-starved demons stay out of humanity's way! What does a ninja do? Fight, with every battle skill and sexual sorcery she can muster!

Shin Injuu Gakuen (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. This time the enemies are Fubuki Kai, a rogue ninja who wants to defeat Miko and claim the title of best ninja, and the cybernetized survivors of the Suzuka clan.
