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...
That's how I felt from 
the bottom of my heart.
هذا ما شعرتُ به من أعماق قلبي
So empfinde ich von Herzen.
Y ahora lo pienso de corazón.
Y ahora lo pienso de corazón.
Je le pense sincèrement.
Ecco cos'ho sperato con tutto il cuore.
Do fundo do meu coração,
foi assim que me senti.
По крайней мере, сейчас я в это верю.
