It's day one of the festival, and Rimuru finally gets to see all of his friends' performances and presentations. As he's enojying the festivities, he's summoned by Luminus...
Please enjoy yourself in 
moderation, Great Rimuru...
...من فضلك استمتع باعتدال يا ريمورو-ساما
Treiben Sie es nicht
zu wild, Lord Rimuru.
Conténgase, señor Rimuru.
Conténgase, señor Rimuru.
Tâchez de rester raisonnable,
maître Limule.
Datevi un contegno, Grande Limur.
Por favor, divirta-se com
moderação, Rimuru-sama.
Только не заигрывайтесь там,
Великий Римуру.
