It turns out that Glass, like L'arc, is also a hero from other world. Naofumi barely fights off their combo attacks and then corners Glass in a one-on-one battle, but is then faced with an all-important question: does he truly wish to protect this world?
Once I finish fighting off the Waves, 
I'll just go back to my world.
حالما أنتهي من مقاتلةِ الموجات
سأعود إلى عالمي فحسب
Wenn die Wellen besiegt sind,
werde ich einfach in meine Welt heimkehren.
Cuando terminen las olas,
volveré a mi mundo.
Cuando terminen las olas,
volveré a mi mundo.
Je rentrerai dans mon monde
quand on aura vaincu les vagues.
Una volta terminate le Ondate,
farò ritorno nel mio mondo.
Quando isso terminar,
eu voltarei pro meu mundo.
Как только расправлюсь с Войнами,
вернусь обратно в свой мир.
