Megumi Fushiguro

He was left an orphan after the death of his mother, and his father, Toji Fushiguro, was a famous curse user. Secrecy; Reluctance to be a hero; Doubt and insecurity; Heartlessness towards criminals; Justice and belief in goodness; Pragmatism and analyticalness; Restraint and introversion; First-year student at the Tokyo Jujutsu School, descendant of the Zenin clan, wielder of the rare cursed technique "Ten Shadows"
His half-sister, Tsumiki, is among the players, and Megumi enters the game primarily to save her. He truly loves his sister and worries about her, so he's willing to risk his life to rescue her from this nightmare. Kenjaku initiated the migration to push humanity toward "evolution": to optimize the cursed energy and ultimately merge all humans with Tengen. Megumi and his team are determined to prevent this.
He entered the competition with Yuji Itadori to find a way to free Tsumiki. The key idea was to use the points accumulated in the game to propose and approve new rules that would help bypass the deadly traps.
For example, they proposed a rule whereby a player could leave the Death Migration by spending 100 points and bringing another player in return. This offered a chance to save Tsumiki without resorting to assassinations, which was the primary way to gain points.
he is not familiar with Hana and her companion
Gojo Satoru is sealed and only Hana can free him due to her technique under the psychic "Angel"
