As a much-needed break from his sleuthing duties, Conan is looking forward to reading some newly-borrowed manga in the evening; however, once more, duty calls! Kogorou Mouri has been asked by the wife and daughter of the Raizou family to protect a Treasure Sword that has been "claimed" by the Kaitou Kid; however, Mine Raizou and his mother are certain they can handle the problem themselves. Conan, the Detective Boys and the rest of the gang must defend against Kaitou Kid's raid with the help of the young swordsman Yaiba!
Meimi Haneoka is a typical girl with a not-so-typical double life: by day she attends St. Paulia School, and by night she transforms into the phantom thief Saint Tail! Stealing only items that deserve to be stolen, Meimi takes her orders from the nun in training Seira Mimori. But even with the best of intentions, Meimi can't help but have a few enemies; her classmate, Asuka Jr., would love nothing more than to unmask Saint Tail's identity. However, Meimi can't help but be intrigued by her dashing opponent. Thievery galore and young love await the magical Saint Tail!
There are plenty of detective or thieves anime out there, but Kaitou Saint Tail and Conan OVA 1 have a somewhat similar feel in particular. Sure, Conan is not aimed at young girls while Kaitou is mahou shoujo to the max, but both have the same lighthearted comedic feeling. If you liked Conan OVA 1, you might appreciate Kaitou Saint Tail as well.
