I Do Not Own Anything.

~ Synopsis ~
One day, students in a certain high school were transferred to another world where they immediately got attacked by hostile monsters. Facing total annihilation, they were only saved by some of the students, whom discovered that they have gained cheat-like abilities.
"Cheat" was originally a word meaning to trick or deceive, but now it's used as a term in games to mean something not originally possible, or over-powered in the original system.
Just a week after most of the cheat ability users left to explore the new world, chaos broke out in the Colony where most of the students without abilities remained. The remaining cheat ability users staged a coup d'état and rampaged. Students then started indiscriminately attacking each other.
Takahiro Mashima, despairs in the human race as he barely escapes amidst the chaos into the forest dominated by dangerous monsters with his life, only to encounter a giant slime over 2 meters tall.
