Oresama Teacher Vol. 28 (manga)

Mr. Maki's hired goons have taken over the auditorium! With the stage inaccessible due to the massed delinquents, the school play has to be canceled for "technical difficulties." But disaster is averted by quick thinking and teamwork as the disappointed audience is sent to view the other marvels of the festival. Now all Mafuyu and her friends need to do is take down the huge crowd of invading bruisers! The fight for Midorigaoka is on!
