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 was a long battle.
.لقد كانت معركةً طويلة
Fue una dura lucha.
Fue una lucha dura.
On a mis du temps
à en venir à bout.
È stata una lunga battaglia.
Foi uma luta tão longa.
Это был долгий бой.
