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...
So I guess the instigator 
is someone in the council?
إذاً أعتقد بأنّ المُحرِّض هو شخص في المجلس؟
Der Anstifter dazu
kommt aus dem Rat, oder?
Debió instigarlos alguien del Consejo.
Los habrá instigado alguien del Consejo.
L’instigateur
fait peut-être partie du conseil.
Quindi dietro a tutto questo
ci sarebbe qualcuno del consiglio?
Então acho que o instigador
é alguém do conselho.
Получается, наш противник из Совета?
