Yorozu is a sorcerer from the Heian Era and a participant in the Culling Game through reincarnation orchestrated by Kenjaku. Originally affiliated with the Fujiwara clan, she was known for her eccentric personality, unconventional behavior, and refusal to adhere to aristocratic norms. Despite her status, she consistently disregarded traditional etiquette and lived according to her own desires, earning both notoriety and disdain among the nobility.

Yorozu is a highly skilled user of the Construction cursed technique, which allows her to create physical matter from cursed energy at the cost of extreme energy consumption. Through years of refinement and scientific understanding, she developed highly efficient applications of the technique, most notably liquid metal manipulation and insect-inspired armor that greatly enhance her offensive and defensive capabilities. Her mastery culminates in the development of her Domain Expansion, Threefold Affliction, which enables the manifestation of her ultimate creation, the Perfect Sphere (True Sphere), a construct capable of generating overwhelming destructive pressure.

Across her lifetime and reincarnated state, Yorozu is defined by her obsessive fixation on Ryomen Sukuna, whom she views as the only being capable of understanding her concept of love through strength and solitude. This obsession drives nearly all of her actions, including her participation in the Culling Game, where she seeks to confront Sukuna once more. Despite her immense power, intelligence, and creativity, Yorozu remains emotionally erratic, deeply self-centered, and intensely expressive, prioritizing personal desire and emotional fulfillment above all else.a
