A boy who awakens his memories of his past life wakes up to find himself facing a "zombie crisis." Is this some kind of American variety show world, or the world of Hunter x Hunter?

So the first thing to do now is to escape this city.

Kyle's third time traveling through time brings him to a world far more bizarre and dangerous than those of One Piece and Naruto. The painful experiences of his first two journeys, where he died in swords and kunai upon inheriting his memories, taught him this: if you're not strong enough, you die! Awakening his Nen ability at the age of seven, he possesses the power to turn everything around—the Book of the Unique World Resonance! When Gon needs strength to challenge Hisoka, Kyle extends an invitation: "Sign a contract. I'll grant you the opportunity to train in another world, and you'll grant me the power to reflect back." Thus, the Hunter world's strongest pirate group sets sail, and an organization more powerful than the Akatsuki in the Ninja World is born. But Kyle harbors a deepest secret: does this seemingly fair contract reflect the fruits of training, or does it reflect the fate of the contracted... themselves? As the bonds of the powerful from three worlds intertwine, what awaits them is the path to the highest...

Originally titled "HP: I Died Early and Passed Through the World"

Faye was sickly since childhood and had to stay in the hospital ward all year round. She died when she was less than ten years old. After her death, she was bound to a system and traveled to the magical world.

Little Faye remembered the system novel that the nurse sister had read. The system always assigned various tasks, and there were penalties if they were not completed. She couldn't help but feel a little worried.

The system said: "We are a regular system, not some wild system with a punishment mechanism!"

... ...

Later, Xiao Fei's relationship with the system was indeed as the system said, free and unrestrained. He would often appear from one corner and then disappear to another.

One day, while wandering the castle, Faye saw a fluttering black robe. Having heard so many fairy tales from her family, Faye thought to herself, "Oh! That must be the most perfect wizard!" So she followed...

From then on, the black-haired, black-eyed professor who was the most feared by the students at Hogwarts had a "little tail" with a completely different style beside him...

"Little Tail" would give him his favorite Christmas presents, would accompany him quietly while he brewed potions, would tell him to love himself, and would even use his little hands to "slap" his head when he unconsciously belittled himself...
