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...
A sword doesn't have a soul, 
and thus, no will.
السّيف لا يملك روحاً، وبالتّالي بلا إرادة
Ein Schwert hat keine Seele.
Entsprechend hat es auch keinen Willen.
Las espadas no tienen alma.
Por ende, voluntad tampoco.
Las espadas no tienen alma.
Por tanto, voluntad tampoco.
E una spada non possiede un'anima.
Uma espada não tem alma e,
portanto, não tem vontade.
У меча никакой души нет,
а значит, и воли тоже.
