Practicing Jujutsu Kaisen in the Ninja World

Thanks for the invite. I'm in the shinobi world and just got out of the hospital!

All around me is a crowd of black-robed people, their eyes feverish and crazed. There's also a gray-haired man with a slicked-back hairstyle named Hidan, laughing brazenly at me.

That's because I'm the second person to have successfully 'survived' this selection ritual and become a 'lucky' recipient of an [Immortal Body].

Akagi Shinji is feeling a little numb...

And what's even more frustrating is that after the modifications, this body of mine has chakra but can no longer learn any ninjutsu.

That means I'll become the first immortal loser of a ninja!

But the activation of a bizarre System has brought a whole new turn to my life.

Can't learn ninjutsu?

No problem!

There's all kinds of amazing cursed techniques for you to choose from!

Blood Manipulation, Straw Doll Technique, Ten Shadows Technique... you name it.

Wait a minute!

Why is there a [Cursed Wind Tunnel] here too?!

Does that even count as a cursed technique?!!!

Whatever. Domain Expansion: Unlimited Void!
