Maki Zenin, born January 20, 2002, into the prestigious Zenin sorcerer clan, endured systemic abuse as the elder twin of Mai Zenin due to her near-absence of cursed energy and reliance on specialized glasses to perceive curses. Her father Ogi dismissed her as a failure, while her unnamed mother secretly trained her in weapon combat, nurturing her tenacity. Defying her family, she fled to Tokyo Jujutsu High, determined to ascend as a sorcerer and dismantle the clan’s oppressive hierarchy. Initially ranked Grade 4 despite her skill, Maki relied on unmatched physical strength and cursed tools like swords and the three-section staff Playful Cloud, gifted by Satoru Gojo. She mentored first-years Megumi Fushiguro and Nobara Kugisaki, stressing weapon mastery and tactical awareness. Though stern, she forged bonds of mutual respect with classmates Panda and Toge Inumaki. The Shibuya Incident left Maki scarred by Jogo’s flames, shortening her hair and searing her arms, face, and torso. Adapting a sleeveless uniform, she intensified training, her physique hardening as she prepared to challenge the Zenin clan. This resolve crystallized after Mai’s sacrificial death: using her final breath, Mai forged the Soul Liberation Blade—a replica of Toji Fushiguro’s weapon—while erasing Maki’s residual cursed energy. The act finalized Maki’s Heavenly Restriction, granting Toji-level physical prowess, immunity to domain detection, and heightened senses attuned to environmental shifts like air density and temperature. Empowered, Maki slaughtered the Zenin clan, executing Ogi and cousin Naoya, who later returned as a vengeful cursed spirit only to fall again. In the Culling Games, she moved at blinding speeds, severing souls with the Liberation Blade and allying with Noritoshi Kamo against curses, persisting through grave injuries. During Sukuna’s Shinjuku Showdown, she ambushed the King of Curses with the Split Soul Katana, enabling Yuji Itadori to rescue Megumi. Stoic yet compassionate, Maki masked vulnerability with bluntness, initially clashing with Yuta Okkotsu before mentoring him. She guided Megumi with familial loyalty, rejecting Zenin traditions while bearing their legacy. Her appearance evolved from a ponytail and rectangular glasses to cropped hair and circular frames post-Shibuya, scars and a bandaged right eye marking her trials. A muscular build underscored her reliance on raw strength, symbolizing her defiance and redefinition of power.
