Nagumo Hajime was called useless by his classmates, and that didn’t change when all of them were suddenly transported to another world. Called upon to be heroes, they were each given abilities upon transferring, but to no one’s surprise, Hajime’s wasn’t very useful or exciting compared to his peers. When they were taken to a dungeon for training, things didn’t go as easily as they had hoped.

Betrayed and left for dead, Hajime fell into the deepest section of the abyss, a place where even veteran heroes would be as good as dead. Through sheer grit and determination, Hajime was forced to claw his way through hell just to survive from one grueling moment to the next. Completely alone and abandoned, Hajime must contend with the some of the most ruthless demons and monsters of any isekai world.

16-year-old Hatsushima Sasae’s father passed away three months after remarrying a beautiful young woman, gaining Sasae a new family. It hasn’t been long since his death, and Sasae has barely adjusted to living with his new stepmother and her two younger sisters. Now the unexpected has happened and they’ve all been transported to another world. This world is overrun with a demonic race known as the Dead Mell who devour men and rape women.

All the world’s kingdoms are held in fear by the Dead Mell, thus a desperate summoning ritual was held to call forth the strongest Familia. By pledging themselves to the gods of this world, the four of them can achieve greater strength and potentially counter the vicious spread of Dead Mell. But the dead are only half the threat, as not all the kingdoms see the otherworlders as saviors and merely tools. This manga provides a horrifying look at a world where normal humans can’t hope to last long, no matter where they happen to go.
