It's summer. The gang's on a southern island, and there's cute girls in swimsuits abound. Arata's cooking yakisoba for some reason, but these things happen. The quartermaster is repairing the school that Arata destroyed in his collapse phenomenon. The girls enjoy a mixed-gender bath, and the demon lord candidate decides on a theme--control.
Yeah. I'll show you that I can 
control it, so send me back.
Ja. Ich werde beweisen, dass ich das
beherrschen kann, also schick mich zurück.
Claro, lo controlaré, 
así que puedo regresar.
Claro, lo controlaré. Así 
que puedes llevarme de vuelta.
Oui, tu vas voir.
Sì... Ti dimostrerò che sono in grado
 di controllarlo, quindi mandami indietro.
Isso, eu vou dar conta de 
tudo, então me envie de volta.
