Having reached a place he can't return from, Subaru realizes just how much he has been given and how little he can do to repay any of it. After remembering what he must do, he says goodbye to Kenichi and Nahoko and heads to the school. Steeling his resolve, Subaru opens the door to the classroom, where he's greeted by Echidna in a school uniform. When Echidna says he arrived much sooner than she expected, Subaru responds that she looks good in the uniform.
Show your gratitude to me for making it
 by drinking every last drop.
أظهر الامتنان لي على إعداده
بشرب كلّ قطرة منه
Agradece que te haga uno bebiéndote
hasta la última gota.
Agradece que te haga uno
y no dejes ni gota.
Sois déjà reconnaissant
que je l’aie préparé moi-même.
Dovrai mostrarmi la tua riconoscenza
bevendolo tutto quanto.
Seja grato por eu ter feito e tome tudo.
Не забудь поблагодарить за то, 
что трачу на тебя время!
