Kou Voravong
Kou Voravong grew up in Savannakhet and pursued a primary education there. He obtained the « certificat d'études primaires complémentaire indochinois » - Certificate of Indochinese Additional Primary Studies - (CEPCI) in 1930, went afterward to Vientiane and began his first-secondary-school year at the Collège Auguste Pavie. But because of a conflict which opposed him to French Colonial administration, his adopted father was sentenced to prison that same year. As reaction to this situation, Kou Voravong left school and returned to Savannakhet. As an out-of-school teenager, he practiced sports, especially soccer.
Dairangers
Kou initially kept his identity a secret from the other Dairangers, with Byakkoshinken speaking in his stead to appear more grown up. After the other Dairangers learned of his identity, he began to speak on his own and joined the team. Shadam eventually learned Kou was his son and Akomaru's twin brother, although Kou himself was never aware of this. As a result of this knowledge, Shadam tried to recruit Kou into the Gorma on his tenth birthday, but his mother's baptism purified him of his Gorma lineage. As Kiba Ranger, Kou specializes in sound-based attacks and his Mythical Qi Beast is Won Tiger.Kou is portrayed by .
