Meikyoku to Dai Sakkyokka Monogatari presents short biographies of famous composers such as Beethoven, Schubert, Mozart, Chopin, Vivaldi, Johann Strauss, and Tchaikovsky. Notably, the less widely recognized Stephen Foster, known for pieces like "Beautiful Dreamer" and "Jeanie with the Light-Brown Hair," receives an entire episode dedicated to him, likely because his songs were popular during Commodore Perry's arrival in Japan in 1853. In contrast, Bach and Handel are covered together in a single episode.

Will this unusual group discover the truth behind the supercomputer's deeds and save all of humanity?
