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?
Don't you want to teach Itsuki 
and the others a lesson?
ألا تريدين أن تلقّني إتسكي والآخرين درساً؟
Willst du dich nicht an Itsuki
und deinen falschen Kameraden rächen?
¿No quieres demostrarles
que se equivocaban?
¿No quieres demostrarles
que se equivocaban?
Tu veux pas montrer à Itsuki
et aux autres qu’ils ont tort ?
Non vorresti dare una bella lezione
a Itsuki e a quel branco di idioti che ti ha cacciata?
Você não quer dar uma
lição no Itsuki e nos demais?
А не хочешь проучить Ицуки,
товарищей, что тебя выгнали?
