Zenin Maki is rendered in the distinctive Q Posket style, featuring oversized, sparkling eyes and a soft, rounded facial expression that captures her resilient spirit. The figure stands poised with one hand resting at her side and the other slightly raised as if ready for action. Her hair is sculpted in long, glossy strands that frame her face, with subtle shading to convey depth. She wears the Jujutsu High uniform: a dark blazer with crisp lapels, a white shirt, and a dark skirt, accented by a belt and practical footwear. The base is simple, ensuring stability while not distracting from the character.

Zenin Maki is introduced in Jujutsu Kaisen as a determined student from the prestigious Zenin clan. Lacking innate cursed energy due to clan politics, she relies on meticulous training and mastery of cursed tools to fight. Throughout her journey she faces discrimination from her own clan while demonstrating exceptional skill in close combat and weapon work. Her determination to prove herself drives her to push past barriers, form alliances with trusted colleagues, and endure harsh missions against deadly curses. Her growth culminates in major battles where strategic thinking and precise execution prove she is among the most formidable sorcerers.
