Fish Story
フィッシュストーリー (original)
A rock band writes a song called "Fish Story" based on a sentence from a badly translated novel by a quack translator. The song exceeds the boundaries of space and time and ties people and their stories together. Thirty-seven years go by, and the song strikes a comet and saves the Earth from total destruction.
