Juujika no Rokunin

Labeled “Experiment A” by five of his classmates

and tortured throughout sixth grade,

Shun Uruma hung on by a thread.

When his bullies targeted his family,

leaving him with nobody but his grandfather,

it was the final straw—Uruma had suffered enough.

Determined to get back at his enemies,

Uruma begged his grandfather, a WWII veteran,

to guide him through the path of vengeance.
Four years later, Uruma completes his intense training

and embarks on a brutal journey of torture

and retribution to hunt down the five monsters

who made his school life a living hell.
