Description
Seikai Miyoshi-nyudo begins as a resident of the Izumo shrine. He shares a close adoptive sibling connection with Isanami, both raised by the shrine's head priest, fueling his protective nature towards her. Loud and outspoken, he frequently displays jealousy when Isanami interacts closely with others like Saizo, yet shows genuine care and readiness to help her in trouble.

He is a tall man with tanned skin, typically dressed in white clothing and a blue loose scarf over white loose pants. His accessories include a cross necklace, a white headscarf, beaded bracelets, and a large beaded chain. He consistently carries a spiked mace wrapped in bandages around the handle as his primary weapon. The "Nyūdō" suffix in his name denotes his Buddhist monk status.

His journey starts with a conflict against Kakei Jūzō over unpaid food, escalating into a fight interrupted by Saizo. During this confrontation, he reveals his search for Isanami, whom Saizo calls a "monster." The situation intensifies as other Braves engage him until Isanami appears. She initially fails to recognize him and accuses him of thuggery. After repairing the damaged area, he recounts his history to the group and presents childhood evidence to Isanami, leading to her acknowledgment of their relationship. Impressed by his dedication and recognition of Isanami’s hairpin (Kushi-mitama), Sanada Yukimura invites him to join the Braves as the Earth representative.

He integrates into the group, participating in communal activities like the hot springs incident where he jumps into the women’s section and is frozen by Anastasia. His combat emphasizes brute strength, utilizing techniques such as "Tenbatsu" (Heaven’s Punishment), a forceful punch breaching walls; "Rokkon Shojo: Namu Amida Butsu," a sweeping mace slam repelling foes; "Hannya Harami," a direct overhead smash; and "Taizan Meido," a vertical strike with crushing force.

While historical records suggest he may have perished during the Osaka Campaign, the anime adaptation does not explicitly depict his death.
