Even after losing the duel, Glenn lacks all motivation. Yet through his interactions with Sistine and Rumia, he eventually starts genuinely teaching classes that will help them. Meanwhile, suspicious men show up at the academy…
There's no other field that excels 
so much at killing people.
.ما من مجالٍ آخر يتفوّق عليه في قتل النّاس
Eine bessere Mordwaffe gibt’s nicht.
No hay otro campo
que sea tan bueno para matar.
No hay otro campo
que sea tan bueno para matar.
Y a rien de mieux
pour les massacres.
Non c'è niente che
la possa battere in questo campo.
Não há outro campo que 
seja tão bom em tirar vidas.
Ни одна наука не преуспела
настолько в смертоубийстве.
