Guri has gone missing. Seiji seems unphased while Akane is thrilled but Yuzu is deeply concerned for her friend and begs Seiji to seriously look for Guri. Meanwhile, Shikimi is up to no good and Seiji catches her in the midst of trying to trick Kusunoki-sensei. Seiji drags Shikimi away to save the hapless teacher, but winds up having the tables turned on him when she traps him. A confrontation boils up and Guri finally falls from the sky, literally, to ask Seiji how he truly feels about her.
Yeah, because the little monkey 
hasn't been around lately!
¡Es porque el pequeño mono
no está por aquí!
¡Es porque el pequeño mono
no está por aquí!
Ce ouistiti n’est pas là,
en ce moment !
Perché ultimamente
la scimmietta non si vede in giro.
É porque a macaquinha 
não aparece faz tempo!
Да, всё потому,
что этой мартышки нет рядом!
