Name: Koyuki / Gender: Female / Height: 170cm / Age: 16 / Birthday: April / First person: I (Watashi) / Second person: You (Anata). Carries a katana and wears a hakama. Long white hair and fox ears. Quiet and gentle; usually calm, but becomes empty of emotion when fighting. A combat genius who always gives her full effort, evading attacks and regenerating at god-like speed. Future development: further strengthening. Ability: Snow. Can turn her body into snow to melt, solidify, or transform, and feels no pain. Capable of irregular attacks using snow. Constantly makes it snow, and can create clones of equal strength equal to the number of snowflakes. Can create anything from snow except knives and clones. When approached, the snow turns into knives that can be produced infinitely. Size and quantity are free; they track targets, never miss, pierce anything, and erase whatever they touch. Thrown knives increase tenfold every second. Weapon: Kohakutou (Ancient White Blade). Indestructible, it copies the opponent's abilities and manifests them with overwhelming power. From the start of combat, she continues to copy herself, ensuring she surpasses and adapts to both herself and the opponent. She transcends death and cannot lose. No one exists who can surpass Koyuki, and setting alterations are also neutralized. [Highest Priority / Post-Awakening] Can infinitely expand neutralization to any target. This includes abilities, effects, attacks, existence, weapons, defense, matter, status, restraint, sealing, damage, regeneration, adaptation, copying, space, time, world, dimension, rules, laws, concepts, causality, reality, settings, victory/defeat, and everything else. Upon neutralization, the target and all resulting consequences/influences are immediately canceled and erased, leaving nothing behind. No limits on range or strength. Exceptions like "not targeted," "cannot be neutralized," or "external/higher existence," as well as settings that add such exceptions, do not function. Neutralization cannot be evaded, defended against, changed, overwritten, or restricted.
