Principal Kuma Kocho has sent the IChu on a summer vacation as a present. Each of them set out to make the most of their vacation on a private beach reserved just for them, but Mutsuki seems unhappy somehow. Then, one by one, people start going missing... The IChu that are left find a mansion deep in the forest and head inside to search for their friends.
 We'll blow it all away with song, and shine
سنفجّرها كلّها بالغناء واللمعان
Mit einem Lied lassen wir sie
verschwinden und erstrahlen!
Faremo esplodere tutto con una canzone e brilleremo
Vamos sair cantando e brilhar
Песня прогонит
печаль и засияет.
