[Anime Crossover] Does Natsume Have to Exterminate Cursed Spirits Too?

Overnight, the world's demon power increased by 10,086.

At first, the youkai were just going through a slump. Then even some lesser youkai learned to speak.

After that, strange black marshes and bizarre trails began appearing.

And finally

"Aaaah! What's that?!"

"There's a youkai! Aaaah!!!"

Only when the girl sitting next to him screamed and fell to the ground did Natsume finally understand what all those strange signs had meant...

After the world somehow merged with a parallel world, three exchange students transferred to Jujutsu High.

One was reserved but thoughtful. Every day, they muttered, "This time, I have to help Natsume," then buried themselves in their studies and physical training. For some reason, they also occasionally spoke in Buddhist aphorisms.

One was adorable and straightforward, always making strange noises at an ugly cat, and wielding talismans with impressive skill.

And the so-called "Natsume" was the ugly cat's owner. He looked delicate and frail, and stood out among the local Jujutsu High students like a crane among chickens, almost like a mascot.

Setting the transfer students aside, after the worlds merged, a new kind of energy appeared alongside cursed spirits. The transfer students called them youkai. Cursed spirits could corrupt youkai, and the two could combine to create even more powerful cursed spirits.

Jujutsu sorcerers: Exorcise anything that harms people!

From the front lines:

A Jujutsu High student from Natsume's year who wished to remain anonymous: "Natsume, that skinny blond one. Isn't he supposed to be the mascot? Why can he punch cursed spirits and youkai apart?!"

"And that book of names in his hand is so creepy! How does shouting out a name summon a shikigami?!"

"What blond hair? The one I saw had white hair, like a fairy, flying around on a huge white shikigami! He was tearing through everything in the sky!"

"And his shikigami roster is bottomless! What does that even mean?!"

Everyone looked at one another. "Where on earth did Gojo-sensei find these transfer students?!"

[Before You Read]

This story has a mountain of original worldbuilding. It's mainly about the worlds of Natsume and Jujutsu Kaisen merging, with Natsume traveling between the two worlds to exorcise cursed spirits and save humans and youkai.

Though he's been forced into a hot-blooded action manga, the characters' gentle nature won't change.

Theme: To form no bonds is to invite no loneliness.
