The Sadean Empire believed the gods had granted them a new world of glass and steel to enslave when the Gate stabilized in Ginza. They were catastrophically wrong. The dimensional rift fractured upon entry, bridging modern-day Tokyo not just to a medieval fantasy realm, but directly to the border of the hyper-advanced Jura Tempest Federation. For JSDF Lieutenant Youji Itami and Sergeant Shino Kuribayashi, the battlefield becomes completely surreal when the leader of the monster forces steps into the crossfire. Shimmering with the terrifyingaura of a True Demon Lord, the silver-haired king drops his terrifying presence to complain about his ruined weekend in perfect Japanese. Well your not interested in the description then just read the story.

Just a random crossover to another anime or novel world

Future Rimuru rewinds time to his Demon Lord evolution to fix everything, but instead gains a desire-manipulating skill that causes lust-driven chaos and forces him to wear a blindfold to control it.

The world of Remnant has always been filled with mysteries-Dust, Aura, the Grimm, and the immortal struggle between Ozpin and Salem. But one day, a new mystery arrives. Without warning, a strange blue-haired man appears near the Kingdom of Vale. He possesses no Aura, no Semblance, and no known history. Yet he effortlessly destroys a massive Grimm horde without lifting a finger. Calling himself Professor Rimuru Tempest, he accepts a teaching position at Beacon Academy. Unknown to everyone, this "human" is actually Rimuru Tempest, ruler of the powerful nation of Tempest from another world. Using his Ultimate Skill and dimensional travel abilities, he has opened a portal to Remnant simply out of curiosity. Even Ozpin cannot discover the truth. Even Salem cannot understand what he truly is. And the longer Rimuru stays in Remnant, the more the balance of the world begins to change. Because the greatest monster in another world has become Beacon's newest teacher.

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.
