Koetsuji Akisame is the philosophical Jujitsu master and doctor of Ryozanpaku, an old friend of Miu's father, Fuurinji Saiga. He was the first master to agree to train Kenichi, though he shows the least concern for Kenichi's feelings.
Despite his seemingly small frame, Akisame has muscles built to perfection. He possesses sharp insight into people's minds, often detecting when they are troubled or hiding something. Sometimes, he even knows what a person is thinking, which unnerves Kenichi.
Akisame has numerous hobbies and unique abilities. He is a renowned artisan who has mastered calligraphy, painting, pottery, and sculpting. He frequently invents devices that serve as training equipment for Kenichi and power sources for the dojo, such as a treadmill generator.
He runs an orthopedic clinic and can easily reset and fix bones. His extensive knowledge of medicine and anatomy led him to develop unique physical conditioning methods. His medical skills are so advanced that he once saved Apachai's life despite a gaping hole in his side, performing surgery using tools from Shigure on an airplane. Among doctors, he is known as "The Medic Demon," and they fear him.
Akisame seems to hold a grudge against James Shiba, Takeda's master, evident from James's frequent insults about Akisame's mustache. This rivalry escalated to a point where they bet their mustaches would be shaved if their disciple lost the match.
