Ten years after the end of the Great Tenma War, the world is finally at peace. Rimuru Tempest has become something beyond comprehension-a godlike being with uncountable power, unlistable skills, and a divine weapon forged from Genesis-class blades. And yet, buried beneath his calm smile and mountain of paperwork lies a quiet, aching regret. He couldn't save Shizu. He couldn't reach the Ogres in time. Despite all he's built, those moments still haunt him. But when a single question leads to an impossible answer, Rimuru realizes one thing: With his current power, even time itself is no longer a limit. Now, Rimuru travels back to the past-to rewrite his story, save the people he loves, and create the perfect future he once dreamed of. This is a story of second chances, deep regrets, and a god who still carries the heart of a slime.

When time itself halts in Teyvat, the winds of destiny shift. In an enigmatic chamber far beyond the skies of Celestia, every important soul across Teyvat - from archons and Fatui Harbingers to knights, adepti, shrine maidens, and even the sharpest tacticians - is summoned by an unseen force. A mysterious hooded figure known only as Kabir Singh stands at the center of it all. With a single snap, hundreds of glowing letters reach every corner of the world, bearing an invitation too compelling to ignore. What awaits them is not a battle, nor a divine trial - but a revelation. A chance to witness the full journey of the one known as Rimuru Tempest: his rebirth, his rise, the formation of Tempest, and his path alongside the Traveler in Teyvat. From the depths of his original world to the most guarded secrets of his power, nation, and the Twelve Guardian Lords - truths shall unravel. Hidden memories may surface. Bonds will be tested. This is a reaction-based crossover experience set between the cracks of the main story - meant to not only entertain, but to deepen the understanding of Rimuru's world and how it intertwines with Genshin's. All while giving the author time to prepare the next phase of the real journey. And remember: only those who know the Traveler and Rimuru can witness this. Characters not yet seen remain cloaked in invisibility - present, but unseen. Civilians are absent. Only playable characters, with their memories from the fanfic canon intact, have been chosen to gaze behind the curtain. Let the reactions begin.
