Go, Go Second Time Virgin

Plot: Tsukio is a young, traumatized boy who roams an apartment building. On the roof, he witnesses the rape of a young girl (Poppo) by a group of delinquents. When they are done with her, the two find comfort in each other's company. It turns out they have suffered the same trauma, and both of them are struggling to find reasons to continue living. When the delinquents turn on them again, they decide to stand up against the group and show that they can't be messed with. Their anger drives them to take proper revenge, but even that doesn't relieve them of the emptiness eating them up from the inside.
