Shinigami in the Ninja World - What If 12: Danzo’s Death, Eternal Mangekyō Sharingan

In the City of Crime, one law stands above them all: Only the strongest can live.

Urano, a bookworm who had finally found a job as a librarian at a university, was sadly killed shortly after graduating from college. She was reborn as the daughter of a soldier in a world where the literacy rate is low and books were scarce. No matter how much she wanted to read, there were no books around. What is a bookworm to do without any books? Make them, of course. Her goal is to become a librarian! So that she may once again live surrounded by books, she must start by making them herself.

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.
