From the Start, I Have Ryujin Jakka: I Storm the School to Save My Sister

Gray fog blankets the globe, and the apocalypse descends upon the world.

More than 60% of humanity turns into zombies, chaos erupts, and the world is plunged into despair.

But no one could have imagined...

that zombies were merely the appetizer for the disasters to come.

Parasites, xenomorphs, mutant monsters, wasteland exclusion zones, demons, the Fallen, Devourers, and one disaster after another follow.

The world is fraught with danger, and death could come at any moment.

Fortunately...

On the first day of the apocalypse, Chu Qianshan awakens the Doomsday Survival System while trying to save his younger sister.

His beginner reward is the Zanpakuto: Ryujin Jakka!

All things under heaven turn to ash: Ryujin Jakka!

The Bankai, Zanka no Tachi, will cut down all that is impure!

And that's not all. Chu Qianshan will unlock the Mangekyo Sharingan, the Rinnegan, the Ice-Ice Fruit, the Glint-Glint Fruit, the Three Types of Haki, Dragon-Slaying and God-Slaying Magic, the Serious Punch, Ultra Instinct, and many more abilities!

And so, a seemingly ordinary young man quietly becomes the most terrifying boss of this post-apocalyptic world...
