If you liked the Magical Canan anime, the Anime-Planet community thinks you'd like:
Nanoha used to be a normal grade school student until one day she found a ferret in the woods -- but he's no ordinary ferret! His name is Yuuno, he hails from another world, and he needs Nanoha’s help to complete his mission: to capture the Jewel Seeds (mysterious stones that imbue their wielder with great power) that fell to Earth. Along with Yuuno, Nanoha must now collect the Seeds and protect her world, but she isn’t alone. A rival is also trying to collect the Seeds for an unknown purpose, and only Nanoha has the power to stop her…
In Nanoha and Magical Canan, the main male characters transform into animals. The two series also contain some romance and a bit of school life with comedy. Try out one if you liked the other! :)
Both Nanoha and Magical Canan are 13 episodes long and they have many similarities, especially in the first episode. Nanoha and Chihaya find a cute animal and take it home, which is actually a boy from another world. It gives them magical powers and they have to help him out by collecting Jewel Seeds in the case of Nanoha, or magical seeds in the case of Chihaya. They later have to face an antagonist and there's more action with lots of flashy magical attacks.
Both Magical Girl Lyrical Nanoha and Magical Canan start their stories with with a Male from another world disguised in an animal form going to Earth in order to collect Magical Items that could destroy the world. They Both Have a Small Amount Of Ecchi, And Both include Comedy and have similar Plots.
Sakura Kinomoto never imagined that by opening a book in her father's library, she'd be responsible for releasing wild magic into the world, yet that's exactly what she did. Too powerful to be let loose on the world, the magical Clow cards were sealed away long ago by their creator, Clow Reed. But all is not lost, for the guardian beast, Keroberos, was sealed along with the cards! Can Sakura, with the help of Keroberos, retrieve the cards before they wreak havoc on the town?
If you liked Magical Canan, I highly recommend Card Captor as a step up to a better series with much of the same charm. CCS also features a girl possessing magical powers that must fight to protect her family and friends and a little side kick that helps her along the way. Bust CCS is also a longer series which allows the story to go deeper into the background of all the characters. By the end of the series as well as the movies, you will have fallen in love with Sakura and her tenacity.
Masaharu Tsuwabaki ('Haru') had been living a more or less normal school life until, one day, he accidentally drinks a potion that transforms him into a tiny doll-like lamb at night. To lift this curse and return to normal, he must work with his "chosen girl" Sumomo Akihime, a very shy girl in his class. She is given powers by a magical ring, and together they must hunt down mystical artifacts called stardrops in order to return him to normal. At the same time, Tsuwabaki must keep his daytime identity a secret from Sumumo as well as keep their ability to use magic hidden. As he lives this double life, he grows closer and closer to Sumomo in both his human and sheep forms.
Both heroines find themselves with magical powers out of the blue, which isn't entirely coincidental since they have a parent that is from another world. Although at first they have no idea they have magical powers. Chihaya has to collect magical seeds while Sumomo has to collect star drops, and they also have to deal with a rival girl who is in the same class as them.
