Before we start: Just wanted to say that English is not my first language and so I'll probably have my fair share of errors on the story, if you want to point them out i appreciate, it means that i can correct my mistakes and hopefully don't make them again, i plan to post once or twice a week, first chapter will be posted either later today or tomorrow (not really sure right now), Arthur will of course be paired with Tess

Name: Aster Leywin

Appearance: Fujimaru Ritsuka (Fate/Grand Order)

Elements: Fire, Water, Air, Lightning, Sound and Ice

Beast Will: Pretty much Kokushibou skills from Demon Slayer, First stage only has a speed and strenght boost, Second stage provides extreme regenerative powers (can regenerate missing limbs in seconds, can still be killed by a strong attack), Transparent World (Allows the user to see the muscles, blood vessels, organs, bones and mana core of the target), Flesh Manipulation (can alterate own body at will, changes stay even after the user stops using the second stage, allow also for sword manipulation since the sword is an extension of.the user body)

Breathing Style: Moon Breathing (part of the "Beast Will", can't use the seventh form or any form above without having the second stage active

Breathing Forms (c+v from KNY wiki):

First Form: Dark Moon, Evening Palace  - Kokushibo quickly draws his sword and slashes swiftly in a singular horizontal motion in a crescent shape, creating numerous chaotic crescent blades. This technique is extremely reminiscent of Iaijutsu.

Second Form: Pearl Flower Moongazing  - Kokushibo performs several crescent-shaped slashes that defend him from incoming attacks, sending a barrage of crescent blades.

Third Form: Loathsome Moon, Chains  - Kokushibo swings his sword rapidly in two gigantic crescent slashes, from which a storm of smaller crescents spread, causing huge destruction in a small area.

Fifth Form: Moon Spirit Calamitous Eddy - Kokushibo makes multiple curved slashes layered over one another, creating a rising vortex of sword slashes and crescent moon blades.

Sixth Form: Perpetual Night, Lonely Moon - Incessant  - Kokushibo releases a wild barrage of crescent-shaped slashes several meters in front of him. This technique was powerful enough to overwhelm Sanemi Shinazugawa and so long-ranged that it slices up the surrounding pillars.

Seventh Form: Mirror of Misfortune, Moonlit - Kokushibo swings the gigantic version of his sword in a powerful frontal crescent-shaped slash that creates powerful multi-directional long-ranged slashes in the ground.

Eighth Form: Moon-Dragon Ringtail - Kokushibo uses the gigantic version of his sword and creates a singular gigantic crescent-shaped slash that slowly decreases in size, creating dozens of crescent moon blades.

Ninth Form: Waning Moonswaths - Kokushibo creates a stream of long-ranged crescent-shaped vertical and horizontal slashes along with numerous crescent moon blades with the gigantic version of his sword.

Tenth Form: Drilling Slashes, Moon Through Bamboo Leaves - Kokushibo creates a long-ranged triple-layered slash twister full of crescent moon blades with the gigantic version of his sword.

Fourteenth Form: Catastrophe, Tenman Crescent Moon  - Kokushibo uses the gigantic version of his sword and creates a chaotic vortex of powerful extremely long-ranged omni-directional slashes that destroys whatever is caught up within its attack radius.

Sixteenth Form: Moonbow, Half Moon - Kokushibo creates a barrage of downward crescent slashes from an extremely long and wide range, resulting in a powerful six-fold slash crashing down on his opponents; the attack itself is powerful enough to create several miniature craters where the slashes have landed.
