- Description from novelbuddy

In a world where its inhabitants can destroy a city wall single-handedly, the empress has a kirin as her pet, and the imperial palace of Great Xia has a pool containing a dragon. There is also a Sword Mountain where spirit swords occasionally leave in search of a master .

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.

Silas Blackwood wakes up with a machine in his chest – his missing mother's parting gift to help him survive the war with the Fae. This “system” grants him bizarre abilities: neuromancy (magic of the mind), biomancy (magic of the body), and essomancy (magic of souls and essences). Oh, and it fused a leviathan's mana core into his body. Because why not become part sea monster?At Arcanium University, a military boot camp churning out mage knights, Silas finds himself targeted by rich brats who think being born with a silver wand up their ass makes them special. When they leave him for dead, Silas decides it's time to show these spoiled kids what real power looks like.As Silas grows stronger, he discovers he can upgrade himself by absorbing essences from magical beasts and demons. Just when he thinks he's got a handle on things, Silas learns his mother's alive, and now he's got a new mission: a rescue that'll take him and his friends straight into the depths of Hell.
