"Naraka High School is a seemingly normal school. However, unknown to the public is the cruel truth of what really goes on in the school’s halls. Rather than studying, students are forced to struggle for their very survival. And the strong bonds of friendship may be the only difference between life and death
Naraka High School is a school open to anyone who is able to see the floating island. To the public, it is portrayed as a regular high school, while the students inside are the only ones, with the exception of past graduates, who know the truth."
I've made it a small goal of mine to get this manga known aha. It's still ongoing and is a really good read!
