The X gene was directly modified to correspond to a Devil Fruit. Aliases: Pirate; started as a tiger, wolf, and dog, constantly entangled with Kaido; previously received many negative reviews for calling Whitebeard "Old Man," but has since corrected his ways and changed it to "Big Brother." Currently one of the Four Emperors.

Lin Yu transmigrated to the world of Demon Slayer. Awakening the Character Inheritance System, he immediately inherited the legacy of the blind swordsman, Fujitora Issho. Thus, a swordsman of unparalleled skill and mastery was born… “This swordsmanship!” “Is this really a sword that a human could wield?!” Kibutsuji Muzan collapsed to the ground, his face filled with unprecedented terror. Kibutsuji Muzan once again experienced the terror of being dominated by that figure four hundred years ago, even more terrifying than before. “This oppressive feeling…” “Perhaps, compared to us, you are the monster.” Upper Moon One, Kokushibo, stared intently at the man standing before him. Having experienced the terror of that man four hundred years ago, Kokushibo could better understand the terror of the man before him.

After his death, Xia Mu arrived in the afterlife.

When I opened my eyes, all I saw was a vast desert, with a pale moon hanging in the sky.

Then, another all-white monster attacked him.

Just when Xia Mu thought he was going to die, a figure dressed in black and wielding a long sword appeared and dealt with the monster.

Everything is moving in a positive direction.

Unexpectedly, an even bigger monster appeared, and before he could even ask the man who saved him his name, the man died.

In order to survive, Xia Mu had no choice but to pick up the long sword left behind by the man and fight.

He didn't know that the moment he grasped that knife, he had become Death himself!

I'd better take a good look! Elbow, come inside with me!" Freya: "I was here first, Levi, you should look at Seele too!" Ishtar: "Be my godfather, and all the girls in the Pleasure Quarter will be yours." Aphrodite: "Freya and Ishtar both like you? Does that mean if I steal you away, I'll be the most powerful goddess of beauty?!" Artemis: "How dare you summon the Artemis Arrow without my permission?!" Demeter: "Levi, thank you for saving my child." Astraea: "Young man, I feel your justice~" Hestia: "You thieving cats, stay away from Levi, you bastards!!!!" ...ps: The goddesses liking the protagonist ≠ the protagonist liking the goddesses.
