The Rainbow Eyed Devil and His Songbird

Swap Counterparts Meet

It was the most critical moment in their lives.

Douma ready his fans, looking up at the demon that taunts him in his dreams, singing him sweet lullabies.

Her eyes had slits, donning the kanji for Uppermoon Six. She had made much progress in a short amount of time and had gotten into the Kizuki ranks.

Now he was here to slay her.

"Uppermoon Six! I will slay you today!" Ice Hashira Douma had declared. Opening his weapons of choice, fans he has held since he received them. Golden fans that will cut the heads of any demons in his way.

Even the one he loved.

Soft giggles could be heard from the female demon who dances on the Lilly pads. So light on her feet and had a smile wide on her face.

"My love! You know me! My name is Kotoha-" Douma slams his fist on a pillar, shattering the wood under his rage.

"NO, YOU HAVEN'T BEEN KOTOHA SINCE YOU TURNED!" Douma had to hold an infant Inosuke that day, crying at seeing her massacre his congregation. He couldn't kill her then.

"I WILL SLAY YOU TODAY!!" Douma was lunging, intending to go for her head.

Only the fortress air shifted and before him was not the Kizuki demon.

It was Kotoha wearing a slaying outfit, donning the golden buttons of the Hashira. His momentum was too much, if it was an illusion he would slash through it.

But her gaze was as furious as his, blocking his fan with a blade of yellow.

"DOUMA, STOP PLAYING GAMES!! YOU WILL DIE TODAY!!" Douma lands on the wooden planks, not understanding how. He looks around, watching out for a demon who must have done an illusion on him.

She was human. She was acting human.

His fury came full force.

"Stop playing games Upper Six, I will-" A blade was directed at him.

"Upper Two should know a thing or two about games!"

That's when they suddenly realize something.

This was all wrong.

Douma had been lunging at his beloved slayer, wanting to hold her in his arms even if she stabbed him in the chin. She had done it before and would do it again if given a chance.

His grin falls, confusion crossing his face as he collides with another demon that looks much like her. Claws embed into his back as they splash and are soon jumping onto the wooden planks.

They are stepping away from each other slowly, looking up and down at each other before looking around.

His heart was breaking.

Did his lord Muzan take his slayer away? If so he needs to find her before another demon gets to her. This fortress is quite dangerous.

It seems his friend, though looking like his beloved was feeling the same.

Where were their slayers?
—

They still had their weapons trained on each other. His however was beginning to shake, tears brimming his eyes.

"You know you are beautiful! You look a lot like my son! He'll be turning five soon!" The female slayer, oh how she looks like Kotoha only a bit more hardened, lowers her sword.

"You aren't Douma, are you? Douma, Uppermoon Two of the Kizuki." Douma shakes his head.

"No, I am not. I am the Ice Hashira."

Kotoha hums, her grip tight.

"And I am the new Sound Hashira."

The sounds of other battles could be heard.

This was wrong.

It didn't stop the shift to happen again.

It was a wrap of space, merging together, a reflection, and the other side was coming to say hello.

Before the slayers knew it, the temperature dropped along with the sound of a note beginning. Kotoha with her sword in hand tries to cover her ears as the sound becomes piercing.

Douma feels his lungs struggling to breathe.

A claw hand takes hold of Kotoha's chin while another is gripping Douma's collar.

"My! What a handsome face! Kotoha-chan, don't tell me you were planning to run off with him?" Uppermoon Two leans in, not believing his eyes at seeing those familiar colors in his counterpart.

"She is quite pretty, I can understand why you would chase her." Uppermoon Six strokes her captured Hashira's chin.
Both slayers are soon scowling, even when in pain, ready to die to fulfill their duty.

Uppermoon Two grins at his demon companion.

"We are the same you and I! We love ourselves some slayers!" Douma then is being tossed and so is Kotoha, both exchange a look, before angling themselves at the demons they are being thrown at. Weapons ready, they cry out.

Uppermoon Two leaps up to meet his beloved while Uppermoon Six wants the dance to continue.

Clashing metal can be heard as Kotoha's attack is blocked by the Kizuki. From the corner of her eye, she can spot the darting form of Douma. A claw hand finds her chin once more as they fall.

"Does Kotoha-chan like him better than me? Should I remind you why I am yours~?" It was a purr and it reminded her of the only mistake she had made as a slayer.

She slashes for his head but he stops it with a closed fan.

Then he kisses her, tongues dancing and hands finding the back of her head. Tears stream down her face and her fist weakly lands on him.

Oh, she hated him.

But her love was so hard to let go.

—
Douma roars, water splashing as he unleashes another breathing form on her.

"Hahaha~ Douma, She was beautiful! Did I look like that as a human?" There was a moment where an old memory came to her. Douma doesn't stop as he charges her. Tears come to her eyes as she imagines the little one she had what felt like an eternity ago.

"Inosuke must be so big now." Douma nearly choked, having never mentioned their son's name in her presence.
—
These two worlds would be separated once more.

Though the demons weren't all that fazed, the slayers were rattled at the thought of how different their lives could have been.
