If you liked the Kobato. anime, the Anime-Planet community thinks you'd like:
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 anime have cute characters and the plot is similar: To collect something (candy in Kobato. and stardrops in Nanatsuiro Drops) to achieve a certain goal. Both anime also have talking plush toys to guide the heroine. In both anime, the heroine faces many obstacles and falls in love with someone. The ending is also somewhat similar. If you loved Nanatsuiro Drops for its cuteness, Kobato. probably has more humor and funny moments that I can think of in Nanatsuiro Drops. So if you like one, you may very well like the other.
Eighteen years ago, the Platinum Tiara, which gives its wearer magical powers, was reassembled. At the same time, five "Princesses" were born, to the worlds of Earth, Heaven, Celestrial, Fairy, and Hell. These five princesses quit maturing at the age of 10, and are all competing to become THE Platinum Princess so they can grow up. This story is centered on Yuuchi, from the kingdom of Earth.
Both Kobato and Petite Princess Yucie involves a girl with her own goal, whether it be Kobato wishing to get to the place she wants to go or Yucie becoming a Platina Princess - either way, each anime deals with the two aiming for their own goal and getting nearer to it through their own actions. Both have the same feel to them with each being cute yet serious at times and involving many dealings with helping other people. If you enjoyed one, you'll definitly love the other.
