Full Name: Seto Koji
Live Action Movie: Tonari no 801 chan, Moshidora, Judge, Boku wa Tomodachi ga Sukunai
Live Action Dorama: Koizora, Otomen, Atashinchi no Danshi, Tumbling, Kabuka Boraku

If you’re a fans of tokusatsu series, you’ll recognize this guy as Wataru Kurenai, the main character in Kamen Rider Kiva. However, Setomaru starts his career on one year training in the comedy drama “Rocket Boys” as the main protagonist. After winning the 2nd wining Award of Watanabe’s Entertainment’s official 2nd D Boys audition on 31 July 2005, he then joined the energetic boy band, D-Boys. He’s currently singing under the unit group called D☆DATE.

For that reason, Setomaru moves from his hometown in Fukuoka and lives in Tokyo. He’s been living there for 17 years (born on May 18 1988). The A blood type guy was given the role of Kikumaru Eiji for Tennis no Oujisama Musical (Tenimyu) by the same time he start working on DBoys. he’s the third Kikumaru cast for the musical where he work with fellow D Boys’ member, Tomo and Masato Wada. Now you know why he is called “Setomaru”, right?

Given the role in tenimyu and tokusatsu series is a good step to be great. In 2007, Setomaru plays Shitsuji (Butler) in Happy Boys. He also played the otaku boy friend for DVD only release movie, “Tonari no 801 chan” at the same year.

PERSONAL LIFE

Setomaru is the oldest among three. His first sister, Saori is one year younger. She’s currently working as a model (mostly for Nonno). They also another younger sister named Arisa *thanks for the info Alex*
