From the anime Onegai My Melody, Uta Yumeno is My Melody's human friend. (My Melody is a magical bunny from the forest of Mari Land). They meet when My Melody comes to earth after escaping a dungeon with her foe Baku. They bring with them a magical power that could either hurt humanity or protect them in the form of magical notes. Uta and My Melody vow to protect the dreams of the people against Baku who wishes to destroy them.
Why I like her: She's a cute girl and doesn't act super annoying like most magical girl heroines act. She is always willing to lend a hand and help out any way she can. She has a great love for music and finding romance too.
Why I hate her: No hate here.... Oddly.
Overall: Fluffy fluff fluff. If you need a really girly magical girl anime to watch I suggest this one. It does seem to be aimed at really young girls so be careful. Uta is a fun lead girl and it's oddly entertaining to watch a pink bunny and a black bunny battle it out for pink or black musical notes.
