Rimuru has returned to Jura after having attended Walpurgis. Diablo informs Rimuru of his mission to deal with the Kingdom of Falmuth. Having presented the kingdom with three options at a resolution, the clock on the week for their answer ticks down.
That someone was 
the monsters' leader, Great Rimuru.
كان ذلك الشّخص قائد الوحوش، ريمورو-ساما
Es war der Anführer der Dämonen,
der werte Meister Rimuru.
El señor Rimuru,
el líder de los monstruos.
El señor Rimuru,
el líder de los monstruos.
Il s’agissait de maître Limule,
le chef des monstres.
Si trattava del capo delle bestie magiche,
Esse alguém era o líder dos
monstros, o Rimuru-sama.
И, представьте себе, это был
не кто иной, как владыка монстров, Римуру!
