Former captain of Hyotei's tennis team, bears the No. 9 badge on the first string. Though he and Atobe have never met, Atobe credits him as the one who brought Hyotei to the national level. Of all the taciturn characters in the series, Ochi is perhaps the most stoic and unsentimental. He rarely speaks, and when prompted, usually says something along the lines of "I don't care" or "not interested". On the court, he has perhaps the fastest serve of all the Japanese players known as the Mach. Owing to his ideal height and reach, Ochi can perform high speed serves to the corners that are difficult to see, let alone return. He is also known as the Mental Assassin, as eye contact with him at close range can greatly increase the stress and anxiety a player feels, which translates into committing many unforced errors. Despite losing the No. 9 badge to Atobe, he remains part of the U-17 team for the world tournament.
