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'm sorry, that just startled me...
...أنا آسفة، أرعبني ذلك فحسب
Tut mir leid, ich habe mich erschreckt.
Pardon, je ne m’y attendais pas.
Chiedo perdono, mi hai sorpresa!
Me desculpe, acabei me assustando...
Простите, я просто не ожидала…
