Kaitou Saint Tail is a cute show. It's a bout a girl who turns into St. Tail
and steals stuff. The stolen stuff are usually requested from the orignal
owner. She also helps people out in doing so.

St. Tail always has one rival to look after when she's on her 'thieving'
trips. Asuka Jr. has been trying for a long time to reveal the true
identity of her. Asuka has the rank of a detective because of his help
in the past for the police department. As his reward, Asuka is given a
medal that allows him to truley investigate Saint Tail.

There are some other people that constantly try to find out who she is,
but not like Asuka. Rina, who wants to become the future mayor,
wants to reveal her so she can become famous. Asuka actually likes
St. Tail, so he doesn't really mind when he doesn't catch her.

*Spoilers*
But the truth of who St. Tail is will hurt Asuka and shock him as well.
In the last battle, St. Tail gives up her ways and promises never to steal
or be St. Tail again. In the future, she whacks off her long hair and
marries Asuka. It's a thrilling series to watch.
