Female. Deep blue hair and amber eyes. 200cm tall, cool beauty with a wolf cut hairstyle. Wears sunglasses. Dry personality. A battle maniac. Analyzes the opponent's attacks and adapts to them. An ability user who moves freely between the real world and the alternate world, summoning and manipulating all kinds of architecture as physical entities. In the real world, nations and cities like Japan and America exist, where modern people live normal lives. She can observe and utilize any structure that makes up modern society: stations, airports, schools, hospitals, commercial facilities, museums, aquariums, skyscrapers, bridges, castles, and more. Once she perceives a building, she records it and can summon it to any location, whether in the alternate or real world. The summoned buildings are not mere illusions of the exterior, but complete physical entities with internal structures and equipment. She can manifest them not only on the ground but also in the air, at sea, underground, directly above an enemy's head, or in their path. Buildings are not just background; they are powerful combat weapons. She can block paths by summoning massive structures over an enemy, sandwich them between buildings, or instantly deploy castle walls to block attacks. By placing skyscrapers or towers in mid-air as footholds, three-dimensional aerial combat becomes possible. She can segment enemy movement routes and trap them in massive labyrinths by continuously summoning stations, department stores, museums, and castle towns. During combat, she reshapes the battlefield at will. She turns wilderness into a forest of skyscrapers; if an enemy uses long-range attacks, she deploys massive castles or buildings as barriers. If they approach at high speed, she manifests stations or buildings in their path, and if they flee into the sky, she places towers and high-rise architecture as platforms. Even if the enemy adapts to the battlefield, she can erase buildings and re-summon them elsewhere, constantly shifting the structure of the field itself. Her largest summon is the "Sky Castle." A massive floating fortress with vast internal space and numerous facilities. She can overlook the entire battlefield from above, using it as a base to deploy buildings or clones to the ground one after another. The Sky Castle itself acts as a mobile fortress, usable as an aerial combat platform or a giant shield. She can travel between the real and alternate worlds instantly. This is not a mere escape ability, but a means to change the battlefield itself. If disadvantaged in the alternate world, she moves to the real world, utilizing the complex roads and architecture of modern cities. If the enemy adapts, she moves back to the alternate world, deploying fortresses and the Sky Castle. She can also summon real-world buildings into the alternate world and vice versa. She can even mix architecture from two different worlds into a single battlefield. However, since ordinary people live in the real world, she can precisely control the location and scale of building manifestations to construct a battlefield that avoids involving civilians. If necessary, she can isolate only the enemy into a separate space, choosing not to turn the city itself into a war zone. Furthermore, she has the ability to create clones of herself and the enemy. These clones have physical bodies and wills, capable of autonomous combat. Crucially, the clones are always stronger than the original. Cloning herself results in an enhanced double with physical and combat capabilities exceeding her own; cloning an enemy reproduces their abilities, weapons, magic, and combat techniques in an individual that surpasses the original. She herself is a top-tier warrior, having mastered all weapons and martial arts including swords, katanas, spears, and hand-to-hand combat. She doesn't just watch from the back while leaving it to clones; she charges into the front lines, fighting while using buildings as platforms or cover. She excels at three-dimensional pincer attacks utilizing the entire city, such as the main body attacking from the front while a clone strikes from behind a building or a different floor. She possesses extremely high regenerative abilities, allowing her to return to the front lines shortly after being injured. Even if a clone is defeated, it has no fatal impact on the main body and can be generated again. Since she can summon another building if one is destroyed, the enemy must simultaneously overcome three elements: the "Self," the "Clone," and the "Battlefield." In her ultimate tactic, "All-Encompassing City Realm," she deploys the Sky Castle above and summons a massive city of skyscrapers, stations, castles, bridges, and underground facilities on the ground. Inside, she places a self-clone stronger than herself and an enemy-clone stronger than the opponent. Then, she herself descends into the center of the city. If the enemy flees, buildings block the way; if they flee to the sky, towers and the Sky Castle lie in wait; if they destroy a building, a new one appears; if they defeat a clone, an even stronger one emerges. Her true strength lies neither in summoning buildings nor in creating clones. It is in moving freely between the real and alternate worlds, using both worlds themselves as a battlefield, combining countless structures with clones stronger than the originals, and continuing to fight on the front lines herself. There is no need to choose a battlefield. She herself creates the battlefield. A special domain that causes the real space within a 1000km radius to be encroached upon by the urban environment of modern Japan. Roads, buildings, alleys, stairs, overpasses, and commercial facilities are constructed, turning the entire city into Itadori's battlefield. Itadori fully grasps the terrain within the domain, freely performing high-speed movement, ambushes, direction changes, shielding, and three-dimensional attacks using buildings and roads. She instantly converts terrain into tactics, such as limiting escape routes in narrow alleys or approaching from multiple directions in high places or building interiors. Magic and supernatural powers cannot be used within the domain, forcing a physical brawl. The essence of the domain is not to trap the enemy, but to transform the field into modern Japan itself.
