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...
As you know, 
healing potions don't work on me,
،كما تعلم، جرعات الشّفاء لا تنجع معي
Denn bei mir wirken
Heiltränke überhaupt nicht.
A mí no me hacen efecto
las pociones curativas
A mí no me hacen efecto
las pociones curativas
Les potions de soin
ne font pas effet sur moi
Lo sapete, no, che le pozioni su di me
non hanno effetto.
Como você sabe, poções de cura
não funcionam em mim,
Знаете же,
что на меня зелья не действуют?
