Oh I know! Tohru-chan from Fruits Basket! she's a really nice~ I know she wouldn't hurt anyone and she's been through a lot with her parents "passings"..and having to work..but still I know She wouldn't hurt a fly,she's a really character,so Tohru-chan is my choice.
Tohru Honda from Fruits Basket ^.^ She's always helping others before herself. She can be a bit spacey at times, but she's proven that she cares about everyone por being there for the Zodiac members and helping them find happiness ^.^
Orihime Inoue is definitely the nicest anime character, she wouldn't even hurt an enemy, and she healed the arm of an enemy she had that wanted to kill her friend, she's caring and very nice, she is such a sweet pie

Ukraine from the anime Hetalia. All she ever does is care for her brother and sister, even though she can barely afford to take care of herself. Her brother is nuts in the head and everybody's afraid that he'll mentally snap, but she's the one that brings him lunch and takes care of him all the time. :') And she puts up with Belarus, too.
