The cheery Kobato Hanato is on a mission to heal people’s damaged hearts and gather the resulting “konpeito”; she must collect one hundred of these candy-shaped trophies in order for her deepest wish to be granted: to go to a certain place. Along the way, she’s accompanied by an ever-disgruntled, talking stuffed animal of a guardian named Ioryogi who scores her efforts, attempts to keep her on-track, and reminds her of the rules governing her task: she only has one year to fulfill her goal and she must not, under any circumstance, fall in love with someone whose heart she heals.
Years after having been exiled from the Kannagi household for being unable to utilize their fire magic, Kazuma returns to Japan, only to discover that the Kannagi family's very existence is threatened. Unknown to them, during his absence, he had become a Contractor and thus acquired a vast strength in wind magic. Not showing any remaining contempt for them, he offers to help solve the Kannagi household’s problems in return for large sums of money. Together with his younger brother Ren and the feisty heir to the Kannagi household, Ayano, he fights to protect those he cares about... for a price!
Sawako Kuronuma is just like any other high school girl who wants to make friends and be useful. The only problem is she bears a worrying resemblance to Sadako from 'The Ring!' Because of her reputation, people are not only terrified of her, but small dogs even bark in fear at her presence; in fact, the only person in school who will talk to her is the lively class hottie, Kazehaya. As the pair spends more time together, Kazehaya slowly begins to bring Sawako out of her shell and soon their feelings for each other develop further. Though with her crippling insecurities, lack of social skills, and a series of cruel rumors and misunderstandings, it seems that Sawako's dream of a normal life won’t be quite so easy to obtain.
Both of these series are kind of slow and center around a girl that doesn't quite fit in. Also, as the series progress through a lot of heart warming and funny moments, the lead male and female learn to read their own fellings.
In Amberground, the land of eternal twilight, Letter Bees and their dingos – creatures trained to protect them – deliver mail to the general populace. However, unlike normal mail carriers, their job is perilous as they must traverse the country while fighting off the giant armored insects known as Gaichuu. One day, a Letter Bee named Gauche collects his latest delivery: a young boy named Lag Seeing, whose mother was taken under mysterious circumstances to the capital of Akatsuki. As the pair travels together, they strike up a friendship, but when they finally reach their destination Lag and Gauche part ways. Now, several years later, Lag is about to take the exam to become a Letter Bee himself so that he can meet with Gauche again and find out what really happened to his mother all those years ago. But before any of that, he must find himself a dingo...
Both of these series are kind of centered around "the heart," be it delivering the heart or mending it. Also, each of these series leave a lot of questions unanswered for most or all of the series, while the main character kind of just runs around trying to deliver/mend hearts.
After being threatened by extinction at the hands of alien invaders called the Zentradi, humanity undertook the task of guaranteeing itself a future by launching fleets of colony ships into space. On Macross Frontier, one such fleet, high school student Saotome Alto's life is changed forever: the fleet is suddenly attacked by unidentified creatures while he is performing aerial stunts for a concert by the wildly popular idol Sheryl. Alto quickly finds himself in the cockpit of a new-model fighter struggling to protect Ranka Lee, a young girl he met only hours earlier, from the invaders' swath of destruction. Noting his performance during this incident, the S.M.S. Skull Squadron private military company invites Alto to join their organization, where he continues protecting his friends and Macross Frontier.
Well, both female leads have their own "tune" which they will use now and then in the series. Kobato and Macross both have female leads with a little bit sad pasts (Kobato has better one ;D) and they have this relationship unsolved till the end. (not the "love on the first sight-thing)
They aren't the same, so don't expect anything too much, but they have some same elements and at least I liked them both! ^^
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.
