Space Trash Vol. 1

In 2115, Earth has been abandoned as a lost cause, and humankind has moved on to space colonization. At a decrepit high school on the moon for underprivileged youth, Stab, Yuki, and Una are three teenagers who try to keep their boredom and resentment at bay by fighting rival gangs and cliques, hanging out, and sleeping their way through class, all while trying to avoid punishment from the student council. Fights over turf, respect, and snacks lead to unearthing an exciting secret, but is their friendship strong enough to forge a new future?
