SailorStar9: Well, I've been playing around with this idea for a while, especially after going through the Sailor Moon/Inuyasha section. This will span from the Silver Millennium to the Feudal Era.

Disclaimers: I own not both animes or the pairing.

Plot Summary: Sesshomaru wasn't always emotionless; it had been the Moon Kingdom's destruction that resulted in the death of his mate that left a gaping void in the Daiyoki's heart. But what happens when he finds the reincarnation of his lover during the Feudal Era?

Prologue: Once Upon A Time…

"Athene."

The Mercury Princess turned at the sound of her name, her thoughts broken from wondering about her future. She sat by the fountains of the royal gardens of the Moon Kingdom, her light blue dress fanning on the grass, the water reflecting the being who had called her, his god-like from standing behind her.

"Sesshomaru!" Athene rose and rested her head on her lover's chest. "You came."

The Daiyoki's arms wrapped around her waist, his nose inhaling her familiar scent to ensure she was alright.

"I will never allow anyone to have what is mine." The dog demon promised. He had just arrived some time ago along with his parents, both of whom were speaking to the Moon Queen. Over the past months, the Moon Princess had been persistent in her pursue of the demon. What the Lunaian Princess failed to realize was that she had already failed miserably, for Athene had already won the heart of the Daiyokai long ago. "I will never accept another."

"Yet Serenity still believes she has a chance." Athene reminded.

"She tries," Sesshomaru smirked. "Her efforts are futile. Come, allow me to take you back to your quarters."

"There you are, Sesshy!" Princess Serenity beamed as she latched herself onto Sesshomaru's free arm. "Ah, I didn't see you there, Athene." The Moon Princess levelled a look at the blue-haired girl. "I was hoping I could speak to Sesshy-kun alone." The cornflower-eyes of the Lunaian Princess sent a clear message to her love rival, one that had Athene tap into the 'Soul of Ice' to stop herself from lashing against the Moon Princess.

"I am afraid I must decline, Princess Serenity." Sesshomaru spoke evenly. "We do hope you'll enjoy your birthday ball."

"That's what I want to talk to you about, Sesshy." Serenity whined. "I want you to stop your parents from rejecting the marriage proposal."

"And why should I?" Sesshomaru trained a look at the stubborn Princess.

Said Moon Princess' eyes flashed in anger, "I know of your Mating customs, and I see no Courting Mark on Athene's neck. So, I'm within my rights if I want to woo you."

Sesshomaru's eyes glowed red, his inner beast preventing Athene from turning the Moon Princess into an icicle.

"Athene." Neptune greeted her cousin. "Excuse us, Serenity." She turned a cold glare at the blond Princess.

Serenity pouted and turned her heel to leave. Sesshomaru only regained his composure once the scent of the Lunaian Princess was gone; just how many men had she seduced into her bed?

"I will see you at the ball tonight." Neptune nodded and left.

"Athene," Sesshomaru spoke, his voice deep and powerful. "There is something we must discuss." He sat her on a bench. Silencing her with a clawed finger, he continued, "You know how this one feels for you. My Beast and I have chosen you as our Mate. Do you realize what this means?"

"I do." Athene nodded, her research having revealed that dog demons Mated for; whomever they chose was loved and cherished for eternity. It was not a decision made recklessly' at times, it might take eons to find one's Mate.

"Then, I wish to take you, Athene, Senshi of Mercury, as my Mate." Sesshomaru went on one knee. "Will you do this Sesshomaru the honour and become the future Lady of the Western Lands?"

"Yes!" Athene exclaimed, throwing herself into him.

He picked her up, holding her in his arms as he looked down at her. Her neck and shoulder exposed entirely to him, his eyes glowed red as he sank his fangs into the pale skin between her neck and shoulder, his energy mixing with her blood. Pulling back, he smirked down at his exhausted future Mate; the two purple bite marks and the light blue Mercurian mark slowly darkening. "Come, we will inform my parents."

SailorStar9: Now that's done, read and review.
