Subaru Sumeragi (Japanese: 皇昴流, Hepburn: Sumeragi Subaru) is the fictional protagonist of Clamp's manga series Tokyo Babylon. The head of the Sumeragi clan (皇一族, Sumeragi Ichizoku), Subaru is a young onmyōji in charge of exorcising demons and helping spirits reach the afterlife, while living with his twin sister Hokuto and love interest Seishiro Sakurazuka. Following the events of Tokyo Babylon, an adult Subaru appears in the 1993 live-action film Tokyo Babylon 1999 investigating a murder case. He becomes one of mankind's seven protectors in Clamp's series X, and Seishiro is his new rival. Subaru's fate in the battle of the end of the world has differed across X's multiple animated adaptations. An alternate version of the character appears in Clamp's crossover series, Tsubasa: Reservoir Chronicle.
