Some would say the best way to teach is by example. But for Rentaro's degenerate drunk of a social studies teacher (coincidentally his newest girlfriend), the only way she can teach is by shouting at the top of her lungs, "Don't end up like me!" It's 100 Girlfriends at its most morally corrupt! Will the Rentaro family get hammered together, or will the publisher have to step in before it all gets out of hand?
