''"Acheron..." Merely a borrowed name. You know my nature, remember my deeds... Thus, I am Acheron.

“	I, too, was once kept in someone's heart like you. Those trivial moments, when looked back upon, are worth more than a thousand words... The past shapes who we are today. Some things are hard to remember, others hard to forget.	„

History[]

Acheron lived on Izumo, a planet that orbited a black hole. But when a horde of demons called Kami attack, Acheron has to fight to protect her home planet. But, the Kami soon overwhelm Izumo, leaving Acheron as the only survivor. After killing all the Kami, Acheron slashes at the black hole, falling under IX's gaze and becoming a Self-Annihilator, the Emanator of Nihility. Gradually losing her senses and memories, Acheron comes to Penacony where she meets the Trailblazer and the rest of the Astral Express as well as the Stellaron Hunters. She seeks to kill IX to free herself and the universe from Nihility.

Limited Madness Manipulation (Type 3; Can traumatize those who attempt to look into her mind)
Acausality (Type 2; Acheron does not show up in Elio's script even though he can see an infinite amount of possible futures and she has no past as The Nihility erased it. When one walks on the Paths formed by Aeons, their various possibilities will eventually collapse into a single one, as fate are weaved under their radiance)
Dimensional Travel (12-D, possibly Ω; Emanators can travel through imaginary spaces and the boundary between worlds)
Empowerment, Blessed (Protection & Enhancement) & Imaginary Energy Manipulation (As a Pathstrider and Emanator of the Nihility's path, Acheron is capable of drawing Imaginary Energy from Paths which is a part of imaginary element, with the imaginary space being both the metaphysical world and a higher-dimensional plane. Emanators were directly bestowed power and blessed by their respective Aeons, gaining abilities and resistances related to the Aeon they follow)
Passive Probability Manipulation (When one walks on a Path their various possibilities collapses into a single entity)
Transformation & Statistics Amplification (When Acheron unsheathes her sword to reveal her true powers as an Emanator of Nihility, she undergoes a transformation that increases all of her capabilities drastically and gains a plethora of abilities)
- Enhanced Non-Physical Interaction (Abstractions [Type 1], Concept [Type 1] & Nonexistence [All Natures, All Aspects], 12-D, possibly Ω; Acheron can interact with a manifestation of IX)
- Durability Negation (12-D, possibly Ω; While transformed, all of Acheron's attacks negate the conventional durability, since her sword can cut through dimensions and spacetimes)
- Space-Time Manipulation (12-D, possibly Ω; Drawing her sword causes space and time to instantly freeze)
- Fate Manipulation (12-D, possibly Ω; Acheron can sever fate itself with her blade)
- Pocket Reality Manipulation, Dimensional BFR & Black Hole Creation (12-D, possibly Ω; Acheron can send people to the "Horizon of Existence", often referred to as the Border of Nihility, an endless domain that stands between the boundary of nonexistence under IX's shadow, where there is one of the thousands of IX's manifestations where time is frozen. Those who end up at the Horizon will irreversibly move towards the Border with no possibility of escape)
- Void Manipulation & Causality Manipulation (12-D, possibly Ω; Anything venture into IX will leave nothing behind not even the trace of past and future, as THEY opposed the very concept of existence as Nihility. As an Emanator of Nihility, Acheron has walked the Nihility's Path farthest among the Pathstriders of the same path, being able to deny anything to 'Nihility' of the absolute void, making the enemies and objects vanish from the existence along of their meaning as if they never existed, with Black Swan claiming that Acheron can cut off cause and effect as she did to the history of Izumo and Takama, erasing it to the point the Remembrance cannot recall it)
- Power Nullification & Statistics Reduction (12-D, possibly Ω; Acheron can cut through Xipe's curses and Ena's dreams, and was even able to cut through the Preservation Path itself. After unleashing her true power, her attacks can ignore the opponent's elemental resistance to Fire, Ice, Lightning, Air, Quantum & Imaginary Energy)
