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?
You left them to fight a duo as 
strong as L'Arc and Therese?
تركتهن يُقاتلن ثنائيّاً بقوّةِ لارك وتيريسي؟
tu les as laissées
avec Lark et Tellis,
hai affidato a loro il compito 
di affrontare L'Arc e Terris...
Deixou elas lutarem com uma dupla
tão forte como L'Arc e Therese?
Доверил девочкам сражаться
с Ларком и Терис?
