MTL - Top Quality Beauty Cultivation System - ~ Heavy recommendation "The Peerless Master"

After 2000 years has passed, the ruthless demon lord has just been reincarnated! But his aptitude at an academy for nurturing candidates for demon lords is, “Inept”!?

Having the capability to destroy humans, elementals, and gods, after a long period of countless wars and strife, Arnos the demon lord became sick and tired of all that and longed for a peaceful world, so he decided to reincarnate to the future.

However, what awaited him after his reincarnation is a world too used to peace that his descendants became too weak due to a huge weakening in magical powers.

Arnos enrolled in the Maou Academy established to find any students that might be the demon lord’s reincarnation, but his powers are too extraordinary that those in the academy couldn’t properly judge his powers, so he’s regarded as an “Inept student”. Being underestimated and avoided by most people there, he recruited a girl friendly to him, Misha, as his subordinate and comrade, and strives to climb to the top of the demon race hierarchy to one day reclaim his former title and status.

“Hey, hurry up and massacre those bandits!”

After being reborn she worked hard to stalk and marry her husband, abuse and punish her other scumbag husband, and embark on a journey to reach the pinnacle of life!

—

For the egregious crime of treason everyone in the Xiao House were sentenced to death.

At the execution grounds while waiting for her beheading, she stared at the youth sprawled on the ground in front of her. He had run over so hurriedly he tripped over his own feet, displaying an undignified sight. It made her smile thinking how stupid this person was. She had completely used and taken advantage of him from the day he forced her to marry him. Yet despite all the abuse she heaped on him, he still wanted to save her.

She opened her eyes again only to find it was the day before their wedding. That devious scoundrel… to make her his wife through underhanded methods… The memory of it still left a bad taste in her mouth.

She was going to grab this second chance and live it up! Extort all debts owed to her! Buff herself up and shine like a diamond!

But how was she to know that the husband she once hated was actually really loyal and gentle, soft and easy, and so incredibly sweet and delicious to eat! The shutters that blinded her eyes in the previous life were cast aside. She realized she didn’t know how to cherish the good things in life. So in this new one she was going to make sure to pamper and spoil the hell out of that husband of hers.

“You…” She stepped back. Then back again, her mouth dropped open. “You… You cannot be…”

“I am,” Etan said, and his hair raked back as he pushed his mask off his handsome face. So handsome her heart raced.

His hair was ebony black, his skin a warm brown that threatened to fade in in the winter months. He stared at her with glittering green eyes, over high cheekbones and a noble nose, his jaw tight and shadowed this late in the day. His chin was high over the pillar of his neck that she’d just touched with its hard lines and steel strength, so different to her own. And his chest... She gasped and covered her eyes. She’d humiliated herself revealing her stupid, childish curiosity.

“No, Ayleth. This changes nothing.”

“How can you say that? It changes everything!” She was horrified to realize she was crying.

“Ayleth, please.” His voice cracked on the plea and she stared at him, shoving her mask up and off, despite how it would pull her hair out of the beautiful twist the maid had managed for her.

His eyes locked on hers and she couldn’t think. She couldn’t breathe.

She had met her One. And he was the son of her bloodsworn enemy.

She stared at him as he stepped forward again, offering both hands, palm up. “Touch me,” he whispered. “Hold my hands. This is real, Ayleth. I don’t know how it happened, but this is real. Please don’t deny it.”

She couldn’t resist. She raised a trembling hand to his cheek, letting her palm catch on the scruff of his jaw. He blew out a breath and put his hand over hers, and that jolt that happened whenever they touched shivered through her again.

“Please, Ayleth.”

“I cannot deny it,” she whispered.
