Hiroki Aiba (相葉 弘樹, Aiba Hiroki?) is a Japanese actor, dancer and singer. He is best known for his role as Shusuke Fuji in The Prince of Tennis musical series, Tenimyu, and the live film adaptation. He was also part of a young men's 3-member streetdancing group called Brights, which was disbanded in 2004. His current most known role was the part of Ryūnosuke Ikenami/ShinkenBlue in the 33rd Super Sentai series, Samurai Sentai Shinkenger.
Aiba was a former member of the disbanded three-men streetdancing group called Brights. The other two members included Atsushi Koga and Takuya, who would also happened to later play Akutagawa Jirou in Tenimyu with Aiba. The group had to break up because Aiba had to join Avex (the agency he's currently with) after he won in the Junon Boy contest.
After his work in Tenimyu, Aiba still continues to work as a stage actor, as well as act in several TV dramas. In 2007, he played the title role in the musical Pippin, sharing the role with his Tenimyu predecessor, J-pop singer Kimeru. Since 2008, he is also one of the star actors in the TV drama Tadashii Ouji no Tsukurikata (How to Create the Ideal Prince) along with former Tenimyu cast member Kotaro Yanagi, who plays the lead role.
