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.

Y/n was never able to unlock his sacred gear and for that was betrayed and was left for dead. but what if that was all he needed to awaken his powers? What if he was a soul reaper from the beginning? With his power awakened Y/n now returns to his hometown of Kouh as it's protector. With his return how will he react when he learns that the one who betrayed him never meant to? Will he act out of vengeance or will he search for the truth?

Of the many Re:Zero IFs, it always starts with the protagonist, Natsuki Subaru, making a choice that is different than canon. Though in this world, we meet an IF that begins when a different protagonist makes a choice. A choice that takes his happy isekai dreams, and crushes them into the ground. I, sadly, do not own neither Hollow Knight or Re:Zero. You, the reader own yourself.

After getting killed, you are given a chance to live again but as the Herald of Death. See what adventures await you.
