A brown-haired, homeless man. He is the pilot of the Nova Rhino. Sakuya doesn't seem to care that he is unemployed and homeless. Instead, he enjoys living his life the way it is. Sakuya is the first to (unknowingly) use the original Dancouga's catchphrase "Yatte yaruze!" ("Let's do it!"), which catches on among the team before they even learn its origin. Later, he begins feeling inferior to the rest of the team as Nova Rhino's only function in Dancouga is the pivot foot, and desires a super-strong special attack to make up for it.
