Mitsukake (軫宿?) is the healer of Suzaku's warriors. He is soft-spoken and one of the most serious of the Suzaku Celestial Warriors. He is 22 years old and was born in Sōen Village, near Chōkō of northern part of Kōnan. His true name is Juan Myō (妙 寿安, Myou Juan?), born the star Chariot (軫). Mitsukake's fighting abilities are limited to his own strength, but as a Celestial Warrior, he possesses incredible healing powers at the cost of exchanging some of his own life force. He uses this ability frequently to heal minor injuries, but after healing life-threatening injuries, Mitsukake requires an entire day to regenerate his life force. His cat Tama is the unofficial mascot of the Suzaku Celestial Warriors and, after Mitsukake's death, becomes Chichiri's pet.

The son of a country doctor, he put his natural talents to work and often would help his father with his rounds. His father eventually died attempting to save villagers close to a flooding river during the same storm that claimed the lives of Chichiri's loved ones. Mitsukake shows utter devotion to healing; however after the death of Shōka, the daughter of the local nobleman who he was in love with, Mitsukake gave up medicine and dedicated all of his time and energy into finding a miracle herb that could cure any illness. It was during this reclusive stage that Miaka and the others find him, and managed to get him to join them with little persuasion. However, he continues to cherish the memory of the late Shōka.

Despite his expressionless appearance and tendency to remain silent, Mitsukake is a kind-hearted and calm man who seems aloof, but is actually shy and does not know how to be more outgoing. He is especially kind to the weak, elderly, the sickly, and children, as well as animals. During the battle between Konan and Kutō, he is severely wounded by Nakago. Mitsukake subsequently dies exhausting all his energy to save the life of a child who is later revealed to be the reincarnation of his beloved, as well as all the soldiers who had been wounded during the battle.
