Acheron

Acheron is a tall woman with pale skin, long dark purple hair that reaches her thighs with a fringe that covers her left eye and frames her face, bright violet eyes with pink highlights and diamond shaped pupils.

Her outfit design has Japanese motifs, which consists of a black crop top with a high neckline and intricate cutouts. The cutouts form an upside down V-shape on her chest, Attached to the high neckline is a choker. She wears a white and purple jacket with a long furisode sleeve reminiscent of a kimono. The jacket has intricate black and purple designs. She also wears high-waisted, form-fitting black and purple shorts, as well as black boots. The left boot reaches her thigh while the right boot reaches to just below her knee. She also has a red and purple flame tattoo on her left thigh. She wears a black glove on her left hand while her right hand is covered by a fingerless glove with metallic finger guards covering her fingers. A silver belt with a detailed buckle wraps around her waist. She has various accessories that are chitinous in nature, including a purple shoulder guard, belt, and strap along her spine, as well as a chain around her left wrist, and a large sword reminiscent of an ōdachi.

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. In her alternative form, she has silver hair with a straight, smooth texture that reaches all the way to her thighs. Her skin is pale white and her eyes are red with white pupils. Most of her outfit is now colored in red, white and black. Red, tattoo-like markings are visible on her neck, midriff, and thighs. A few Adenium Obesum flowers are found on her arms, chest and shoulder guard.

Acheron's personality is described as cold and distant on the surface, embodying the traits of an intergalactic ronin and ascetic imperial maiden. However, beneath this exterior, she harbors a quest for revenge, driven by reasons yet to be disclosed. Though aloof and taciturn, her blade flicks out like lashing lightning. And yet, she always strikes with her scabbard, never drawing the sword free. She used to love cooking. However, it's hard to enjoy dishes when she can't really taste anything. Sometimes, Acheron still cook up some food, but it's a shame that she can't taste much anymore. Still, there are some workarounds. For example, She can make ice cream out of snow and Acheron favorite fruit is "Peaches".

Acheron has become so depressed with the world that she accidently stepped on the Path of Nihility, becoming a Self-Annihilator. Thus Acheron knows what will happen, but not what happened in the past, which is why her "memory'' is so poor. From Acheron's POV, the past hasn't happened yet, and she can only predict it based on future events

Acheron is able to cut through reality and dimensions; she can even stop time if she wants to. She's also been shown to be capable of severing the influence of other Aeons, meaning even other Emanators shouldn't take her lightly.

Acheron is hesitant to draw her blade unless she deems it necessary. As a Self-Annihilator, Acheron will gradually lose her senses and memories.

Type 1 (After reaching a certain age in their adulthood, Self-Annihilators just stop aging, overcoming the biological death, being unable to die from any natural causes) Type 2 (Mid; Self-Annihilators can survive having their heads shattered into pieces and ripped off from their bodies for long periods of time, being able to talk normally during these situations that would have instantly killed a normal human as if they never happened) Type 3 & Regeneration (Mid; Self-Annihilators can regenerate their heads from being smashed into pieces and reattach them back to their original positions)

Fearing their makeup would be ruined by the rain, girls carried makeup with them wherever they went. Acheron have no reason to do so anymore, but the habit still remains.
