Plot
At a Tokyo museum of ancient history, Mr. Takagawa, the curator, and Kenji, a janitor, witness the resurrection of the evil Black Samurai, an ancient Japanese warrior whose armor was to be the museum's newest exhibit.
The next day, the Mystery Inc. gang arrives in Tokyo, where Daphne has been invited to participate in a martial arts tournament at the prestigious Mirimoto Academy, run by Miss Mirimoto. The gang meet Daphne's friend Miyumi, who explains the difficulty of winning the tournament and entering the school as a student. After Daphne defeats Miss Mirimoto's bodyguard, Sojo, and almost defeats Miyumi, Mirimoto tells her she shows promise as a fighter. Also at the tournament is Mr. Takagawa, who warns Mirimoto that the Black Samurai has risen and will be after the Destiny Scroll, which is at the school. That night, during a feast, the Black Samurai and his Ninja warriors attack the school and steal the scroll. However, Mirimoto explains the scroll was only a copy, and shows the gang the real one.
