Age (at the start of the show): 29 Yang Wenli is a commodore, currently serving in the 2nd fleet of the Free Planets Alliance. The son of a merchant and a pacifist at heart, Yang never wanted to be a soldier; his dream was to become a historian, but he didn't have the money to pay for his tuition and joined the army to get a scholarship. He barely made it through the officer's academy due to his lack of interest, though he did make a number of friends there including Dusty Attenborough and Jean Robert Lap. He also met music student Jessica Edwards and both him and Lap developed a crush on her, Jessica eventually chose Lap, Yang accepted her decision and they remained friends. Soon after he graduated, Yang became involved in a battle near the friendly planet El Facil, because of his superiors' incompetence and cowardice, the planet was abandoned while a hostile imperial fleet was on its way. Yang was one of the few officers that remained behind and tried to help the population, thanks to his efforts the planet was evacuated in time. Because of this achievement he became famous as "the hero of El Facil" and "miracle Yang," forever earning the envy of his peers and the scorn of his superiors. It was at El Facil that Yang first became interested in tactics, but ever since that incident and although he kept rising through the ranks, his novel tactical suggestions were being arbitrarily rejected by hostile superiors. Though disappointed and increasingly cynical with the state of affairs in the Alliance, Yang never stopped trying to do at least the absolute minimum to justify his salary and the pension he was so looking forward to. Miracle Yang, also called "the magician," is a genius tactician, as well as a competent strategist. Unlike his often proud adversaries, Yang is more than willing to resort to trickery and his only flaw as a commander lies with his inability to go against the orders of his superiors. Yang holds democracy in an extremely high esteem and has a well-defined political philosophy, providing much insight to anyone willing to listen to him. In his personal life he appears to be quite slothful, he is notoriously incompetent with house chores, as well as in all things romantic. After serving on the Patorokolos in the start of the series, Yang eventually gets the battleship Hyperion as he his given command of the 13th fleet, and this becomes his flagship during the coming conflic­ts.

Suguru is a tall, slim, and muscular man with long black hair partially tied up in a bun while the rest drapes down his back. He has thin black eyes and bangs that occasionally cover the left eye. His earlobes are large enough to fit fairly large circular earrings. In 2006, Suguru's hair was much shorter as a student, most of it tied up but his bangs were still as prominent. After August 2007 when Suguru became a curse user, his hair began to grow longer and reflect the length it is in 2017. As a student, Suguru wore a normal jujutsu high uniform. While masquerading himself under the facade of a Buddhist priest, Suguru dons the appropriate attire. He sports a gold-colored kāṣāya garment over black yukata robes. His monk attire is completed with white tabi socks and zōri sandals. Suguru Geto hated non-sorcerers, usually referring to them as "monkeys." He felt sorcerers are the superior race and humanity's next stage of evolution. He was smug and extremely condescending towards normal humans, using fake personas to lure in vulnerable people who were cursed. Suguru found non-sorcerers disgusting enough to spray himself in order to disinfect the "monkey stench." He believed monkeys only have two roles in association with him, money-collecting monkeys and curse-collecting monkeys. If they weren't fulfilling their roles, Suguru would gladly allow curses to kill them without any remorse. (Source: Jujustu Kaisen Wiki)
