Assassination Classroom - Volume 20 | Yusei Matsui

The battle for Koro Sensei's life against a multinational operation's soldiers and weaponry is difficult enough, but now his creator, mad scientist Yanagisawa, and his former protege, Grim Reaper II, join the battle to destroy him-and they've both had major enhancements! But the stakes abruptly change when a 3-E student is fatally caught in the crossfire... If there's one thing that enrages 3-E's teacher, it's harming-let alone killing-his students! Koro Sensei's fury and ingenuity know no bounds, even as fate inexorably catches up to him...
