Kakeru Uobuchi

A temporary coach specializing in jump instruction. Although he is 32 years old, he has a baby face that could be mistaken for a middle or high school student, and people are surprised that there is only a four-year age difference between him and Shinichirō Sonidori. He skillfully uses a harness, a jump training aid not yet fully adopted in Japan, to teach the technique of proper axis correction in the air, dramatically improving jump success rates. With the ideal of raising the overall level of jumping in Japan, he travels across the country as a neutral freelance instructor.
