To persuade Ako to get cracking on her summer vacation homework, the girls have a study session sleepover at Kyoh's gigantic house. However, without Hideki around to keep Ako under control, things soon get out of hand.
In that case, let's call Rusian over, too.
En ese caso, que venga Rusian también.

Appelons vite Rusian !
Ça ira plus vite tous ensemble !
Allora, chiamiamo anch Rusian!
Então vamos chamar o Rusian
também e fazermos em equipe!
