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...
Oh, look at those fish swimming around.
.انظرن إلى هذه الأسماك تسبح
Schau mal, hier drinnen
schwimmen Fische!
Mira esos pececitos nadando.
Mira esos pececitos nadando.
Oh, guarda questi pesci che nuotano.
Oh, tem peixes nadando aqui.
Только глянь, рыбки плавают.
