Rimuru decides to throw a summer festival resembling the ones held in Japan. The monsters have never experienced a summer festival, but when they hear that it's a party, they go all-in to prepare. All the monsters of Tempest work together and eventually come up with masks, paper lanterns, and even festival floats. On the day of the festival, everyone in the town enjoys piping hot takoyaki, cold shaved ice, yukata, and a Bon dance. In the end, they fill the skies with fireworks as the festival reaches its climax...
I didn't think it'd be possible to 
get it without an ocean nearby!
!لم أتوقّع أن أحظى بها دون وجود مُحيط قريب
Etwas, was man eigentlich nur in einer Stadt
am Meer erleben können sollte.
Debería ser imposible conseguirla
sin estar cerca del mar.
Debería ser imposible conseguirla
sin estar cerca del mar.
Comment c’est possible,
alors qu’on est loin de toute mer ?
Non pensavo che sarebbe stato possibile averlo qui,
in un luogo lontano dal mare!
Achei que seria impossível
reproduzir tão longe do mar!
А я думал, что здесь, без моря под боком,
этот вкус не отведать!
