Mio has been captured by Zolgia following Maria's betrayal. Basara too is captured by Lars and brought to Zolgia's mansion. Lars' goal is to exchange Basara for Mio. He explains that he's only doing his duty as Mio's observer, but negotiations fail, and Zest slays him.
Sorry for letting you 
suffer alone up until now.
Entschuldige, dass du bis jetzt
allein leiden musstest.
Perdóname por haber permitido 
que sufrieras en soledad.
Désolé de t’avoir laissée souffrir
toute seule.
Scusa per averti lasciato soffrire
 da sola finora.
Desculpe por te deixar 
sofrendo sozinha até agora.
Извини, что тебе всё это время пришлось 
страдать в одиночку.
