Akuyaku Reijou ni Nanka Narimasen. Watashi wa『Futsuu』no Koushaku Reijou desu! - Chapter 10: Spirits, celebration, and immature adults.

The MC (Minato) is a college student who died in a plane crash and was reincarnated in a fantasy world. He was raised alone in the wilderness by his succubus mother, and now he tries to make his way as an adventurer.

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.

A tree of 10,000 flowers, the world is the door.
The spells change a lot, but the hearts of the people are unchanged.
