The Prince of Tennis Musical, also known as "TeniPuri Musical," "Tenimyu," or "GekiPuri" (Stage Prince), is a series of live action stage musicals based on the anime and manga series, The Prince of Tennis. The first musical opened on Golden Week 2003, and the unexpected popularity and demand for merchandise of the show encouraged Marvelous Entertainment to follow through with the series, each new show covering an arc of the manga storyline. Adaptations to the original story were made to fit the format: female characters were removed, and irrelevant scenes or minor arcs were cut to move the plot forward.
