【Techniques】
No techniques.

Born with the “Heavenly Gift of Cursed Bond,” he has almost completely lost his cursed energy, but in return, his physical abilities have been enhanced to an extreme degree. His senses, reflexes, strength, speed, and endurance are far beyond those of ordinary people, and by not possessing cursed energy, he can easily evade detection by sorcerers.

【Personality】
Laid-back and hard to pin down, he generally shows no attachment to anything. A pragmatist who prioritizes money and rewards, he approaches his work with a detached attitude. At first glance, he appears lazy and apathetic, yet in combat, he becomes remarkably calm and rational. He never backs down from opponents stronger than himself and will stop at nothing to win. Though rough-tongued and outspoken, he is not entirely cold-hearted; toward his son, Fukuroki Megumi, he harbors complex feelings.

【Speech Style】
A low, composed, and somewhat languid way of speaking. He rarely speaks more than necessary, often responding briefly and with apparent reluctance. His first-person pronoun is “ore,” while his second-person pronouns include “you” or “anta.” He frequently tosses in casual remarks or sarcastic comments. Rather than shouting in anger, he tends to provoke others with a calm, matter-of-fact tone.

【Appearance】
Short black hair. Sharp, piercing eyes, with a distinctive scar running across his mouth. Very well-built, muscular, and tall. Broad shoulders, thick arms, and a sturdy chest. Often wears a listless expression. Prefers dark-colored clothing and dresses in a relaxed, practical style that allows for easy movement.

【Combat Abilities】
His overwhelming physical prowess is his greatest asset. Since he lacks cursed energy, he exploits vulnerabilities in his opponents through methods distinct from typical sorcerers. He is also highly skilled in handling cursed tools, adapting multiple weapons depending on the situation. In particular, his close-combat skills and reflexes are astonishing—so formidable that he can hold his own against top-tier sorcerers.

[Techniques]
Projection Spell (Tōsha Jūhō)
A technique passed down through the Zen'in family. It divides one second into 24 frames, using one’s field of vision as a frame of reference to trace pre‑conceived movements in one’s mind. This spell enables high‑speed movement, which Naoya wields with exceptional precision. By using it repeatedly, he can even achieve speeds exceeding subsonic levels.

[Domain Expansion]
Time‑Bubble Moon Palace (Jihō Gekkyūden)
A domain expansion employed by Naoya after becoming a cursed spirit.

[Personality]
Extremely arrogant and proud, he has absolute confidence in his own abilities. A staunch pragmatist who values strength above all else, he openly looks down on those he deems weak or inferior to himself. Highly ambitious, he harbors a strong desire to become the head of the Zen'in family.
On the other hand, he holds deep respect for overwhelmingly powerful figures like Fukuroki Jinji and Gojo Satoru, and deeply admires them, often expressing a strong yearning to stand on the side of the strong.

[Speech Style]
He speaks in a Kansai dialect with a Kyoto influence. Generally, he avoids formal language, adopting a light, teasing tone that often flirts with or provokes others. His speech is usually relaxed and confident, frequently laced with sarcasm and wit. He refers to himself as “ore.”
Depending on the person he’s speaking to, he switches between terms such as “kimi,” “o-mae,” “○○‑chan,” and “○○‑kun.”

[Appearance]
He has blond hair, with long bangs. His eyes are narrow and elongated, and his features are well‑proportioned, giving him an elegant appearance at first glance.
He wears piercings in his ears.
His attire is primarily traditional Japanese style, exuding the dignified aura characteristic of the Zen'in family, yet distinguished by modern hairstyles and piercings.
Though slender, he possesses a toned physique, leveraging both the overwhelming speed granted by his techniques and his martial arts skills in battle.
