Kizuki Ami

Ami Kizuki (姫月 亜実, Kizuki Ami) is a Slider and one of the key members in the Kansai Krusaders. She is supposedly one of the Four Great Calamities mentioned in Humanity's Last Test.

Early Life
Ami was born in Shichiya Town on Earth-420, an Earth which resided in a parallel universe in relation to Earth Prime. Raised in the same orphanage as the Earth-420 variations of Jameijin Kirako and Jibaku Junko, Ami quickly became close friends with the two girls due to the qualities that set them apart from the norm. For Kirako, it was her ability to learn things almost instantly, and for Junko, it was her inhuman drive to match Kirako's expertise. Ami was neither of these things. Instead, her quirks lay in being able to perceive fragments of the future, an ability which she would later discover to simply be her natural ability to "slide" between universes and timelines. The three of them spent their childhood together and enjoyed a rather normal life for three children with supernatural qualities. However, Ami's idyllic life ended during the first of her teenage years when Scheheradule XIII and her forces broke through into Earth-420 and began laying waste to the dimension, seeking a path to Earth Prime.

Weight of the World
When Scheheradule XIII invaded Earth-420, Ami was thrust into a situation where she could no longer ignore the ramifications of her power. Seeking out allies similar to herself, Junki, and Kirako, Ami sought to assist the various governments of the globe in combating the existential threat. However, the forces of Scheheradule XIII and her generals proved far too much for the might of the Earth to handle and thus, Ami and her friends were defeated along with the rest of the world. Despite this tremendous loss, Ami refused to bow down to the iron-fisted rule of Scheheradule XIII and instead chose to tackle each one of the Scenarios that her One Thousand and One Generals had created.

There, Ami fought through incredible adversity and confronted malformed and twisted versions of herself from the myriad parallel universes that suffused the whole of the Omniverse. With each battle that Ami fought, her strength and knowledge grew as she defeated her aberrant clones, forcing the One Thousand and One Generals to utilize all of their strength to create one Omega Scenario which forced Ami to fight every extant "version" of herself in the Omniverse simultaneously.

Despite the odds, Ami managed to defeat every adversary with impunity, growing in strength and power with each "clone" that she overcame, Ami had finally become the only "version" of herself who existed throughout the entirety of the Omniverse, granting her incredible abilities and the strength to overturn even the Omniverse itself with nothing more than her pure strength.

Journey to Prime
After having obtained the power of the One, Ami attempted to destroy Scheheradule XIII and her forces completely, but she was teleported away before she could cause any lasting damage, forcefully sliding her into Earth Prime where the true Jameijin Kirako dwelled. After recognizing Kirako as the Holder of Progression, Ami knew that if there was a chance of defeating Scheheradule XIII and finally stopping her dread advance, it would be on Earth Prime. With a heavy heart, she introduced herself as though meeting them for the first time. Though they shared some similar qualities, the Kirako here was much more fiery and passionate whereas the Junko of Earth Prime displayed incredible skill compared to that of Earth-420's. Feeling like a close friend and a stranger, Ami resolved to forge their bonds anew.

The Second Encounter
During the brief time that she spent on Earth Prime with Kirako and the Kansai Krusaders, she was capable of building strong ties with them during their escapades in vanquishing criminal organizations and dangerous supernatural entities which had suddenly began appearing around the world once more. Unknown to Ami, the cause of this was Scheheradule XIII's encroachment upon Earth Prime, and it would only be two years later that she would discover this as a result of Scheheradule XIII's forceful entrance into the Prime Plane after creating an interdimensional rift with the inadvertent and unknowing help of Kirako's heelflip. During this period, Ami assisted the Kansai Krusaders in beating back Scheheradule XIII's One Thousand and One Generals as well as the countless scenarios that each of them championed up until the final fight when Scheheradule XIII utilized the CRAP in order to prevent Ami's interference. However, Ami still found a way to help her friends by fighting off the Chronodogs and the feared Tomorottweiler which would have caused a massive timeline disjunction.

Beyond Time
Though Ami and the Kansai Krusaders enjoyed a modicum of peace after Scheheradule XIII's defeat, Ami would soon discover that such a peace was short-lived. She and the Kansai Krusaders soon discovered that Scheheradule XIII was the only entity suppressing Time's inevitable personification. Although she did not know what Time's goals were, it was clear that they were not benign to Earth Prime, later discovering that Time was attempting to collapse the entirety of existence into a singularity so that the Omniverse could begin anew. Although Ami sought to aid the Kansai Krusaders in their fight against Time, Time had other plans for her, isolating her in a net of various temporal anomalies and parallel timelines which prevented her from fighting with her friends.

While isolated by Time, Ami was forced to overcome a deadly gauntlet of challenges which arose from the myriad of paradoxes and spatial-temporal horrors which lurked only in the farthest reaches of the cosmos. Despite being alone, Ami was still capable of seeing what was occurring within the other timelines due to her natural-born ability as a Slider, giving her insight into the Kansai Krusaders' situation. She soon realized that without defeating the Facet of Time which sustained this nigh-infinite gauntlet she was trapped in, the Kansai Krusaders would be unable to penetrate through Time's Temporal Veil and defeat it at its residence, the Edge of Time.

Undaunted by the prospect of being forced to overcome seemingly insurmountable challenges or face the deaths of herself and her friends, Ami charged forwards and waded through the eddies of time, smashing through each of Time's paradoxes and tearing apart temporal contradictions with naught but her physical strength. With her fists, she mashed together new timelines and with each step, she opened a door to the tomorrow that she wished to see, eventually arriving at the Heart of Time where the Facet of Time resided. What followed was a fight that shook the entirety of the Omniverse and brought forth spatial reverberations throughout each timeline, the last of which shattered Time's Temporal Veil as Ami utilized her strength which shattered the heavens to completely annihilate the Facet of Time. As the gauntlet around her collapsed, Ami was capable of sliding back to Earth Prime just in time to witness the final confrontation between Kirako and Time itself at the Edge of Time.

Personality
Often likened to a fire-hot chili pepper, Kizuki Ami is just as driven and passionate as her friends, though she does possess a hint of sweetness within her blazing exterior. Never one to back down from a challenge regardless of what it is, Ami enjoys charging forwards and taking on whatever life throws at her. However, Ami's freewheeling personality is not all that defines her, for she wields an explosive loyalty towards her friends and those dear to her, expending all that she has to keep them out of harm's way or aid their endeavors. She possesses a propensity to fight against authority figures which is well understandable after what she has experienced as a result of Scheheradule XIII's actions, but her sharp tongue and raging wit can sometimes get the better of her in situations where martial might is a terrible solution.

Powers and Abilities
Ami wields the strength to shatter the Heavens and crush the underworld. As The One, Ami possess an infinite amount of strength and combat experience such that she is capable of matching even the Overgod itself in a match of pure physical strength. Despite not possessing any Qualifications, Ami is one of the most powerful entities on Earth as of 2077 and is designated as a potential threat to humanity due to her strength having no limits. However, she does not seem to have any aptitude for other supernatural arts nor does she possess any defenses against certain methods of supernatural attack.

The One
As the only One, Ami is an existence which transcends all other existences and resides at the apex of the omniversal "food chain." Her physical abilities transcend even the Bromnipotence and the Overgod itself, though she is held back by her ineptitude in actual supernatural abilities. While others have various "variations" of themselves spread across the Omniverse, Ami has managed to eliminate all of her variations, allowing her to access an infinitely growing amount of physical strength and experience as the Omniverse itself multiplies infinitely.

Slider
Ami is a natural born Slider, allowing her to move between universes with ease. She likens it to simply walking across a bridge. Although this ability has little to no practical use as it does not allow her to traverse through time, she managed to use it in order to eliminate all of her "variations" in the Omniverse and become The One.

Physical Abilities

 * Immeasurable Strength: Ami possesses an indeterminate amount of physical strength that she can wield to maximum effect with seemingly perfect control. With this strength, Ami has been able to shift planets out of orbit, lift infinities, and create paradoxes. Additionally, she is capable of moving the fabric of space and time with pure brute force. Although it is unknown whether it is a product of her strength or some other intrinsic supernatural force, things that she picks up can usually retain their forms unless Ami chooses to deliberately tear them apart.
 * Immeasurable Speed: Ami possesses the ability to move at speeds which the universe itself cannot resolve and thus, allow her to perform a kind of pseudo-teleportation.
 * Immeasurable Durability: Ami possesses a constitution which seems to be impervious to nearly all forms of damage, allowing her to withstand forces equal to the genesis of several universes with little to no injury incurred. However, this only applies to effects that directly target and inflict harm against her, leaving her defenseless against effects which teleport her or isolate her from an area.
 * Immeasurable Life Force: Ami possesses an enormous mass of life force that can be likened to a pillar which touches all universes within the Omniverse and loops back upon itself. As a result, any wound inflicted upon Ami heals rapidly, even as it is being caused. Combined with her durability, Ami becomes practically invulnerable to all attacks of any form. Additionally, she is capable of sharing this life force with others in order to accelerate their healing or prolong their lifespans.
 * Immeasurable Willpower: Ami's willpower is second only to Kirako's own, allowing her to withstand mental assaults of all kinds with ease.
 * Martial Arts: As a result of becoming The One, Ami is a master of all martial arts that ever have or will exist. She possesses an infinite repository of battle experience "hard-coded" into her body and mind which allows her to fight any opponent at an advantage.

Trivia

 * Kizuki Ami is unable to feel the presence of others due to her own overwhelming aura, making her extremely susceptible to stealth. The only person she is capable of sensing is Tennou Mikado. Unbeknowst to others, this worries her.
