With the help of his sister, he hatches a plan to escape the clutches of the throne once and for all. It all goes terribly wrong, and Cairn finds his priorities shifting in the face of unimaginable tragedy. The change of heart comes too late, however, and Cairn dies.

To succeed, Cairn must unite the kingdom and discover the motivation of his killer, using as many tries as it takes. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++I exhausted pretty much every time loop story ever written and decided to write my own. You'll see a few similarities here between this story and some existing stories, at least initially. There's a lot of inspiration drawn from both MoL and Re:Zero, though in terms of pathos and darkness, this story leans more towards the latter. Be warned, it is something of a slow burn. The main character will grow and become powerful, but a theme of this story is that power comes slowly and often at great cost.

Starting life as a college student is hard, but not as hard as dying on your very first day. Ali Asad was just your average guy, ready to start fresh in a new city for college. But when he jumped into traffic to save a mysterious woman, his good deed got him killed—fast and painfully. Just when he thought it was game over, he woke up alive... sort of. Turns out, the woman he saved, Carrisa, had a few tricks up her sleeve. Now resurrected as an immortal being and renamed Alicarde, he’s thrust into a world of ancient power struggles, dark magic, and impossible expectations. Bound to Carrisa’s fate, Alicarde quickly learns that being immortal isn’t all it’s cracked up to be. Instead of focusing on classes or meeting new friends, he’s dodging dangerous foes, navigating Carrisa’s high-stakes supernatural battles, and trying to figure out just what his role is in all this madness. All while struggling with the fact that he really didn’t sign up for any of this. Thrown into a fight for survival with powers he barely understands and a fate that’s now intertwined with Carrisa’s, Alicarde has to adapt fast—or risk dying all over again, this time for good.

800 years ago, 3000 dimensional gates opened across the entire world. In that moment, it was as if 3000 different colored eyes opened across the world as hordes of monsters swarmed out of these gates like tears.

Some could destroy city walls with one strike; They had bodies the size of a giant and fed on humans

Some latched onto humans, absorbing their bodies’ nutrients and enslaving humans

Some infiltrated the humans’ cities, disguising themselves as normal human beings while feeding upon human blood to sustain themselves.

In a night, the Human race fell to the bottom of the food chain.

The world had turned into a paradise for monsters…
