By day, Haruka and Aoi are regular school girls; by night, they’re the Twin Angels, a crime fighting duo! With the help of a mysterious man named Misty Knight the two take down bad guys with ease, but their next opponent will be their toughest challenge yet. An angel statue - a companion to one displayed in their school - is arriving from Italy, and the evil Baron from the Fourth Dimension wants to get his hands on it. It’s up to the Twin Angels to protect the statues and make the Baron pay!
When the students of class 2-A at the all-girls Mahora Academy head back to school, they are expecting a new year as usual. What they get is a new homeroom teacher... who's 10 years old! As if being a genius isn't enough, Negima is a mage. As part of his training to be a Magister Magi, he must succeed at teaching - without anyone finding out he's a magician! Can Negi keep his talents a secret from the girls who just adore the cutest new addition to their academy? Through demon attacks, magical enemies, and English tests, Negi will put all his talents to the test to be the best teacher he can and achieve his goal of Magister Magi.
Both these series have cute girls, magic powers, and mostly short plot arcs lasting an episode or two. Both shows have the girls getting into various situations. In Negima, the Negi does most of the magic, but in Kaitou it's the girls themselves that have the magic powers. But both shows are more about the comedy and characters being cute rather than heavy plots. If you liked one you'd probably want to check out the other.
