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...
The silence in the town sure stands 
out now that the festival's over.
عمَّ السّكون في البلدة الآن بعد انتهاء المهرجان
Nach dem Fest fällt
die Stille in der Stadt umso mehr auf.
Cuando termina el festival,
la ciudad parece más silenciosa.
Cuando termina el festival,
la ciudad parece más silenciosa.
Après le festival,
Quando il festival finisce, il silenzio sulla città è surreale.
Depois que o festival acaba, o silêncio
da cidade fica bem mais evidente.
Едва кончается праздник,
как город поглощает пронзительная тишина.
