Yanaoka (柳岡) is a trainer at Naniwa Kentou-kai and Sendou Takeshi’s second.


Yanaoka is a first class trainer and second whose skills are even recognized by Kamogawa Genji. He is one of the few people who truly understands Sendou. Yanaoka began his career as a boxer and eventually became 1st ranked in Japan, but was defeated by OPBF champion Miyata. After retiring he became a trainer at the Naniwa Kentou-kai.

Years later, a few of his trainees got beaten up by a delinquent named Sendou Takeshi(Who Yanaoka almost knocked out). After Sendou took part in another rumble, Yanaoka turned him onto boxing as a way to find the strength he hungers for.
