The end of the world is coming, the world has undergone great changes, and everything has changed. Plants, animals, and even insects, as long as there are living things, have mutated.
Become more powerful, and even evolved supernatural abilities, such as chickens and ducks that can fly to the sky, such as cats and dogs that can breathe fire.
But only humans, without any obvious changes, seem to have fallen from the top of the food chain to the bottom of the food chain overnight.

But fortunately, this world has not completely killed humans. Gradually, humans discovered that they had the ability to cultivate compatibility with other creatures.
As long as it has a high degree of compatibility with some powerful mutant creatures, it can be used for its own use to achieve the purpose of protecting itself.
Fang He is a person who is very compatible with mutant animals, but it is also because of his ability that he has changed from the strongest to the stupidest.

On that day, due to the outbreak of an unprecedented and abnormal event, 41 students from class 2-7 of Shiromine Academy are summoned to a different world, one full of magic.

Separated and summoned inside a vast dungeon, where the only way to escape is to head to the deepest area, they are given the power of a Divine Protection 『Vocation』 as the only means of survival.

While some of them are brave, some just do whatever they want, and some harbor treacherous intentions, they all aim to capture the dungeon.

In this place, one person gained a 『Vocation』 whose skills are unsuitable for combat, attendance number 19, Momokawa Kotaro.

A boy with a small and lean build from the Literature Club wasn’t blessed with a physical ability, swordsmanship, or strong magic, rather he only had the 『Shaman』 vocation to rely on.

After being driven out of the group and left behind by his powerful classmates —– his survival instinct starts running at full throttle!

Pushed to the limit of survival in the different world’s dungeon, what starts with trusting and loving each other soon ends in killing and betrayal.

The most beautiful and gruesome battle royale has raised its curtain.

Xu Youyou rebirthed to when she was 16 years old and chose a path different from her previous life and met Qiao Mu ten years earlier. The youth who had braved the wind and snow protecting her till death — and who had confessed to her.

And she realized, the Qiao Mu ten years earlier and the Qiao Mu she knew were completely different people. He didn’t have his smile that could radiate sunlight, he didn’t have his courage that could penetrate snowstorms, and he certainly didn’t have his perfect eight pack. He was like a short mushroom, quietly growing in the corner’s shadow.

Xu Youyou: If you dare be like this when you confess to me, you are so dead.

Qiao Mu was a teenage Weiqi genius, he loved Weiqi, but because of his shadow of youth was unable to enter the competition arena. And because of the fear, he was unable to become a professional player and could only return to a typical school life.

Until he met Xu Youyou.

A widely known reckless and fearless girl, who was the complete opposite of him. She was good at everything, except things relating to love. Clearly he wasn’t her type, yet she always provoked him. But the biggest joke was himself, he clearly knew everything, yet could not help but fall into the hands of the enemy.
