Beethoven began as a high school boxer showing rising promise until an injury during a match led doctors to uncover his unique biological compatibility with the musical "Gift" of Ludwig van Beethoven. This discovery secured his enrollment at Gloria Private Academy, an institution nurturing talent across entertainment fields including music, arts, and sports. Students compatible with specific historical composers undergo surgical implantation of that composer's "Gift" and adopt the composer's name as their sole identity within the music department. After receiving Beethoven's Gift, he became known only as Beethoven at the academy.

His personality is cheerful and carefree, often acting impulsively on immediate feelings. He displays a hot-headed streak, sometimes resorting to physical confrontations too readily, yet generally maintains a positive outlook and enjoys fun. Initially reluctant to embrace his musical destiny, he strongly longed to return to boxing instead of pursuing music.

Following his transfer, Beethoven met classmates implanted with Gifts from other famed composers. Through these interactions and his academy experiences, including training to become a musical great, navigating relationships with other gifted students, and participating in competitions, he gradually discovered an appreciation for music's appeal despite early resistance. The academy environment and exposure to peers bearing different composer Gifts contributed to his evolving perspective on music's role in his life.
