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?
Do I care enough about protecting 
this world to crush her hopes?
هل أكترث بما يكفي بشأنِ حماية هذا
العالم لسحقِ آمالها؟
Will ich diese Welt so sehr beschützen,
dass ich ihre Hoffnungen zerstören muss?
¿Quiero proteger este mundo
a costa del suyo?
¿Quiero proteger este mundo
a costa del suyo?
Je veux protéger
ce monde au point
Voglio proteggere così tanto questo mondo
al punto da calpestare le sue speranze?
Eu me importo com este mundo a ponto
de acabar com os sentimentos dela?
Готов ли я растоптать её чувства…
чтобы спасти этот мир?!
