The Last Zero

Kim Jiwoo is a "Zero"

The only person in Seoul who has never had a single drop of mana. In a world where power decides everything, he was born as absolute weakness and there's nothing he can do to change that

While hunters conquer rifts and slay monsters, Jiwoo just wants to live an ordinary life. But one Saturday, a violet crack tears open the sky above Seoul, and he's pulled through to the other side - into a world where magic is woven into nature itself

There, his "zero mana," which everyone back home considered a curse, becomes the one thing keeping him alive. Monsters can't sense him. Spells don't register his existence. To this world, he's practically nothing at all

But Jiwoo is far from the first person to end up here. The "guests" before him vanished one by one... and no one knows what happened to them

As he fights to survive among ancient beings, foreign gods, and sentient monsters, Jiwoo slowly starts to unravel the mystery of the rifts. Meanwhile, back in Seoul, someone is deliberately tearing open new cracks between worlds - using the most defenseless victims of all... children
