Starving Anonymous Series by Yuu Kuraishi, Kengo Mizutani

It’s a day like any other, and high school students I’e and Kazu are on the bus home from school when, suddenly, it floods with a mysterious gas. The pair pass out and wake up to find themselves aboard a truck packed full of human bodies. They’re surrounded by rows of frozen corpses … and a staff of living human beings sawing them into pieces. Where are they … and how can they escape from this nightmare?

They found themselves in a sinister facility where human feelings are transformed into food… Surrounded by death on all sides, I’e, Natsune, Yamabiki, and Kazu manage to escape from the feedlot with their lives…only to discover the Breeders, women who bear child after child behind bars and men who are driven mad by a cocktail of super-strong aphrodisiacs. What other secrets does the facility hold? In volume 2, the fight to survive unfolds in the desolate depths of the prison!

Now, he’s come to the facility where his mother was forced to give birth to him to strike vengeance against its monstrous masters. But he has drawn their ire by killing one of their own, and it’s on the staff to take responsibility. Who will give their lives to appease the monsters?! Despair invites despair as the fight to survive rages on…
