When Sophie enters the living room, she finds Akari and Hinata staring tired and defeated at the table.
She then finds out that summer break is almost over, yet almost none of their homework is finished, 
which is why the two of them are doing a homework marathon.
Then, with progress already being slow, Erie makes an appearance.
She suggests that she could help with the homework, however...
That way, you'll get done faster.
.هكذا، ستنتهيان أسرع
Así acabarán más rápido.
Así acabaréis más rápido.
Ce sera vite terminé, comme ça.
In questo modo, finirete prima.
Assim vão terminar logo, certo?
Так быстрее закончите.
