Yesterday just watch finish the japanese anime called KOBATO..
It about Kobato is a sweet and perky girl, but also extremely naive about the world around her. She has a "mission" to fill her mysterious bottle with people's hearts she heals so her wish to go a certain place can be granted. However, the restriction is that she is not allowed to fall in love with any person whose heart she heals.
As Kobato attempts to fulfill her mission, she is accompanied by Ioryogi, a spirit in the form of a dog plushie. Because Ioryogi is responsible for a punishment that has been applied to him and is friends from the spiritual world, he must guide Kobato and ensure that she succeeds her mission so he and his friends might return to their true form.
CharactersKobato Hanato (花戸 小鳩, Hanato Kobato?)
Voiced by Kana Hanazawa (花澤香菜, Hanazawa Kana?)
A strange and naïve girl with a kind heart, never wanting to see someone suffer or get hurt. She is very innocent and dedicated. It is also noted that she is a beautiful singer. Despite her role as the titular character, she is a bit of an enigma within the series, as her origins have yet to be explained. She seeks to heal the hearts of others, resulting in the filling up of a mysterious bottle called a "flask" with the suffering of those people's hearts so that someday she will be able to go to a certain place that she really wants to go. It has been implied that she came from another dimension. She seems to have no memories of her past.
She has several restrictions: it appears to be that she cannot fall in love with anyone she heals the heart of and she cannot tell anyone of her wish. Curiously she is not allowed to take off her hat in public, though this has yet to be addressed further. Kobato has a very cheerful and enthusiastic outlook in life and her wanting to aid others in need is very heartfelt and sincere. However, she can also be clumsy, rather clueless, and rash with her actions, and often trips over her own feet, much to Ioryogi's annoyance. Currently she works at the Yomogi Nursery run by Sayaka, alongside Fujimoto, where she got a job as an assistant not long after starting her task. Kobato struggles through the series with her feelings for Fujimoto, finally confirming them recently.
Unfortunately, Kobato is forced to pick between two options - complete her wish and never be with Fujimoto or stay with Fujimoto, keeping Ioryogi and the others trapped in animal form. In the anime, the reason why she couldn't take off her hat was because she has a crown on her head and it has been made known that she is actually dead. In the end she was reborn and meets Fujimoto again years later in a mansion. As Fujimoto plays the piano and she sings, her memories came back.
