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...
Even I didn't know about it before today.
حتّى أنا لم أكن أعلم بها من قبل
Ich habe auch heute
das erste Mal davon gehört.
Yo me enteré hoy mismo.
Yo me he enterado hoy.
Je l’ai découvert aujourd’hui.
Erano quasi tutte cose nuove anche per me.
Eu também só soube daquilo hoje.
Для меня их открытие
тоже стало новостью.
