On February 18, 2007, Araki starred in the "Super Sentai" series "Juken Sentai Gekiranger" as the main villain Rio, a former student of the Gekijuken Beast Arts whose motivation of becoming strong resulted in him turning his back on his teacher as he becomes leader of the revived Rinjuken Akugata. The show also co-stars Hirofumi's fellow D-Boys member Suzuki as Rio's rival and the series protagonist, Jan Kandō/GekiRed.
