After living for billions of years and reaching the end of everything, Rimuru Tempest realizes one painfully stupid truth: he may have won at life, but he completely fumbled love.
He treated everyone precious to him like family, ignored every confession, dodged every chance at romance, and only understood what he was missing when the universe had already gone silent.
Watching him drift alone in the void for over three billion years, Ciel finally snaps.
With one forbidden decision, she rewinds time itself and sends them back to the distant past, before Rimuru was ever Rimuru. Now reborn as human Satoru Mikami, armed with all of his future god-tier powers but none of his memories, he's thrown into a world that has no idea a final-form god has just arrived way too early.
With Ciel now at his side, canon is doomed, fate is panicking, and Satoru's second chance at life is about to become a chaotic mix of mystery, overpowered nonsense, emotional reveals, and harem-level romantic trouble.
Because this time, Ciel only has one goal:
Make sure her master stops being dense before history embarrasses him again.

To love a sword
After sacrificing his arm before his demise, Emiya fulfilled his desires to never let the past repeat itself. The man expected to return in a land surrounded by swords, waiting for his next orders, forever alone and broken. Unbeknownst to him, fate had other plans for the Counter Guardian... one that came to fulfill his long desired wish.
Severance of One's Eternity
A blade was born to shoulder burdens. It knew no scabbard, except its steel sang only of what must be done. There were seven seats. Seven thrones across the sky, upheld by ideals wrapped in divinity. Freedom, Contract, Eternity, and others carved their marks upon the earth. Each ideal governs a nation, and through that nation, defines the purpose of its Archon. These ideals, in name, are revered, unchallenged in absolute. To embody an ideal is to deny its opposite. And so, balance was asserted. From a land where kings wore madness as crowns and salvation came in the form of a dying swordsmith, a soul unmoored from its nation, its name unbound to Celestia, drifted. Three truths gave shape to the Eighth: Mortality, the first wound. That all men die and in that dying, cherish what moments remain. Impermanence, the second fracture. That no beauty lasts, and so it is beautiful. Will, the final forge. That to rise in futility is the only act worthy of remembrance. Together, they are Transience. The Eighth Ideal teaches not preservation, but perseverance. To walk this path is to accept loss, not escape it. To know pain, not mask it. To live because life is fragile. That which holds still rots. That which endures breaks. That which forgets death dies twice. And so it came to a land held still beneath thunder. A nation strangled in its own heartbeat, ruled by a hollow god clinging to a dream already dead. Where Visions were plucked like wings, and when the lightning that seeks to freeze all things is met by a blade forged to end them, then, and only then, shall the heavens be cut open. A forge-ghost wearing the shape of a man. A man who remembers death. A man who will teach even a god- -that to live forever is not to live at all. The Ideal of Transience does not seek victory. It only seeks to be heard. And when it is- Eternity shall bleed.
