Galahad.

The last effort of humanity to save themselves, from a world ending threat known as Abyssals.

Some of her past.

Project Galahad.
A soldier who fought for humanity's survival in a space-scale war, one in which she got captured by the otherwordly species known as Abyssal.
Tortured and nearly killed, she had her own DNA and soul fused with the "Eye of the Abyss".
And in an attempt to shame her further for failing, she was sent to another dimension to die.
Eventually found and kept alive in a new cybernetic body given to her by someone she only remembers as "Mentor".

Sent to wander between dimensions, in search of gaining enough strength and skill to finally claim vengeance on her nemesis.

A new body.

Thanks to her mentor's own proficiency in energy manipulation, he was able to stop the effect and stabilize it via a prototype cybernetic body.

As a side-effect of both her corruption and breaking mind, the girl's mind split into two.
One, more calm and rational. The other, wild and psychopatic.

Her cybernetic body still suffers consequences due to the fusion with magic, the contrast between the artificial nature of her body and the divine existence of the Eye of the Abyss, brought her mind to a complete breaking point.
She now suffers ocassional spasms and mental breakdowns if kept unchecked for too long.

Power and abilities.

Eye of the Abyss.

A black colored rock with an engraving on it's surface, the source of an unknown energy.
It is suspected to be the remains of a once worshipped Goddess, as it has incredibly high density and pure seemingly otherwordly energy, as those who come in contact with the liquid which flows out of it become corrupted changing into a once thought extinct race of higher beings akin to angels.

The infusion of this artifact into her body gave her the possibility of growth to extreme heights.

Abilities obtained from the Abyss's Eye:—Extreme durability, lightspeed reactions, speed and reflexes.
—Limited control over reality:
She can create portals by tearing up reality with her bare hands.
Shin'en can slice spots in reality at will, giving it unlimited range and infinite angles.
—Near Immortality.
She will live, even if her entire body is destroyed except for her head.(WIP)

Her weapon.

Shin'en

A one of a kind Blade capable of cutting anything it slices for as long as the wielder believes they can do so.
Before the infusion with the Eye of the Abyss, it was a simple blade.
Once the magical energy of the abyss overwhelmed her body and soul, the sword absorbed some of that energy and became a corrupted blade.

With her own mind and enhanced abilities,
She created her own swordmanship style, yet finds inspiration from many ancient techniques.

Shin'en's special properties:

Shin'en became a divine weapon. Giving it the capability of slaying any target regardless of what they may be.Shin'en has a connection with the concept of the Abyss. A void of darkness, one where slain souls shall never return from.(WIP)
