Kuon has waist-length mint-green hair, styled in a distinctive waterfall braid, with a small tuft that resembles a ponytail sticking out from the back of her head. The ends of her hair subtly transition into a soft peach shade, adding a gentle warmth to her look. She wears two medium-length strands over her shoulders, accompanied by shorter wisps framing her face, which highlight her bright yellow-green eyes, giving her an otherworldly allure.

Her signature accessory is a 3-way satchel bag, likely her school backpack, which adds a touch of practicality to her otherwise ethereal appearance.

Kuon embodies a mysterious, sweet, and delicate nature, presenting herself with an innocence that initially shields her from understanding the true danger of the skyscraper world. Her refined manners and high social etiquette set her apart, as she brings a sense of grace to her unsettling surroundings.

As she journeys alongside Sniper Mask, Kuon gradually reveals her remarkable abilities, yet she remains humble and somewhat naive. Her admiration for Sniper Mask even blossoms into a lighthearted crush, and she occasionally fantasizes about a future with him, despite the age gap between them.

Beneath her pure and timid exterior, however, Kuon occasionally displays a playful curiosity. She reacts with wide-eyed enthusiasm to small details, such as when she inwardly exclaims, “they’re striped!” upon catching a glimpse of Mayuko Nise’s underwear. Her fascination with Sniper Mask’s hidden face and excitement at waking up in his lap add a humorous edge to her character, creating a running gag throughout the series that brings moments of levity to her otherwise gentle demeanor.

Faceless Mask
Kuon has access to a mask that allows her to move undetected and avoid being influenced by the mind-altering effects of the masks worn by others.

Attack Evasion
With an innate ability to evade attacks from other mask-wearers, Kuon skillfully maneuvers through danger, sidestepping powerful strikes from her masked adversaries.

Hibernation Suspension
Kuon possesses the unique power to resist forced sleep or unconsciousness, enabling her to maintain awareness and control when others would succumb.

Railgun Control
Known as the “Railgun User,” Kuon commands a powerful railgun capable of destroying entire buildings. To use this devastating ability, she must have precise coordinates of her target to aim effectively.

Spirit Transfer
Kuon can transfer her spirit or energy across distances, establishing a powerful connection with others through this ability.

God’s Code
As a God Candidate, Kuon is endowed with the “God’s Code,” a mysterious set of powers that elevate her beyond ordinary human limits, granting her supernatural abilities.

Dimensional Stabilization
After conversing with the Supervisor, Kuon gains the power to stabilize distorted dimensions. She can counteract the effects of Yuri Honjo’s abilities, restoring balance in unstable realities.

Mayuko Nise
Driven by a strong desire to protect Mayuko, Kuon activates her “Hibernation Suspension Ability” to nullify Mayuko’s forced sleep, saving her in a critical moment. However, Mayuko’s occasional aggression toward her leaves Kuon feeling a mix of fear and caution, though she remains committed to their alliance.

Yuri Honjo
Yuri is the first God Candidate Kuon encounters in the Realm, and together they form a powerful alliance with Sniper Mask. United by their shared goal to overthrow the creators and bring peace to the World, Kuon and Yuri develop a mutual trust that strengthens their bond throughout their journey.

Sniper Mask
Sniper Mask is the first person Kuon meets, though he initially views her with condescension, seeing her mainly as a source of valuable information due to her status as a “Person Closer to God.” Over time, his attitude softens, and he begins to show genuine concern for her well-being. Kuon, in turn, becomes captivated by his mysterious nature and develops feelings for him, drawn to his complex blend of strength and care.

The name Kuon (九遠) combines “九” (ku), meaning “nine,” and “遠” (on), meaning “far” or “distant.” This evokes a sense of someone connected to a distant, perhaps mystical power—fitting for Kuon’s role as a God Candidate.
