Sirius no Densetsu, Andersen Douwa: Ningyohime Recommendations
Both films are adeptly written stories that are extremely well executed and are guaranteed to make you cry.
A beautiful love story, similar to the tragedy of Romeo & Juliet (but FAR BETTER!), this film has the film quality of Studio Ghibli and a soundtrack composed an orchestrated by the Tokyo Philharmonic Orchestra. It is so beautiful that this music will haunt you for the rest of your life. I highly HIGHLY recommend this one.
