The flowing beauties of time(GiyuShino)

Purgatory of Aether

"Karito Kusho" Muzan said slowly "Kibutsuji Muzan" Kusho replied. The two quickly locked into combat, Kusho swung his scythe into Muzan's abdomen and raised it into the air as Muzan forced his pressure onto Kusho while wrapping Kusho up with black spiked-barbed wires.

Reaper Breathing First Form: Minister's Collection

Kusho throws his scythe with Muzan still on it in a boomerang-like fashion cutting down anything in its way. Kusho runs at Muzan delivering a strong punch before grabbing him off of the scythe, taking hold of him by the throat, and holding Muzan out in front of him, as his scythe returns to him stabbing deep into MMuzan's chest.

Muzan grabbed Kusho's jaw, ripping it out and stabbing it through the roof of Kusho's mouth. A cloud of reality flowed from Kusho, amplifying his strength with his Reality Blood Demon Art. Kusho slammed his scythe down, slightly missing Muzan, and splitting the ground.

Kusho gets surrounded by yellow and blue electricity as he slams his opponent around on the ground. When he finished he flung Muzan into the air, Muzan morphed his torso into a gigantic beastly mouth, and projected a long-ranged energy-like shockwave that severely damages the nervous systems of those caught in it, causing extreme seizures and convulsions, even rendering them unable to breathe for a brief period of time. Kusho performed multiple slashes, dispersing the energy blast.

Muzan surrounded his fists in pressured air, punching the air toward Kusho, blasting holes in Kusho. Kusho used his Eclipse Blood Demon Art to create waves of eclipses at Muzan, homing in on Muzan's body. Slicing off chunks of Muzan's body.

Kusho gets surrounded by Black and Red lightning spinning his scythe in one hand as he runs toward Muzan cutting everything in his path, when Kusho gets close he slams his scythe into Muzan's skull with the crackling lightning making the sound of a scream. "Wow, the forms of Reaper Breathing look really cool!" Inosuke exclaimed "It sounds like each hit is gradually tiring both of them, their regeneration sounds like it's slowing down" Tengen and Zenitsu claimed.

"That means we just need Muzan tired enough in order to land a blow without him being alerted" Yuichiro said. "Aoi has to do it, she's the only one who can perform an attack strong enough to cut his head off" Kyojuro stated "Alright, just tell me when to go" Aoi replied.

Reaper Breathing Fourth Form: Debt Collection

Kusho gets surrounded by Black and White lightning as he slices Muzan's arm off and stabs the scythe blade through one of his hearts ripping it out and eating it in front of him. Muzan placed his hand on Kusho's face, blowing a hole through Kusho's head.

Kusho is surrounded by yellow and blue lightning and raises his scythe making multiple slashes on Muzan's body, as Muzan's arms shoot out his flesh in an upward swing, tearing through Kusho's arm as multiple slashes formed around them in x shapes, knocking Kusho's scythe into the air.

Kusho leaped into the air, grabbed his scythe, and aimed at Muzan while keeping himself airborne via his Reality Blood Demon Art.

Reaper Breathing Sixth Form: Asura

Kusho gets surrounded by Black and Red lightning as parts of the lightning form four more arms and two more scythes.
