Rimuru becomes the new teacher for Shizu's students. However, having been summoned into this world against their will and facing shortened lifespans as a result, the children's feelings are complicated, and they're reluctant to accept Rimuru. So Rimuru proposes a series of mock battles with each of them to ascertain their abilities and allow them to let off steam.
Hah! So long as you don't sic that 
dog on us, we won't need ten minutes!
ما دمتَ لا تحرّض ذلك الكلب علينا فلن نكون

¡Mientras no nos eches a ese perro,
no necesitamos diez minutos!
¡Mientras no nos eches a ese perro,
no necesitamos diez minutos!
Quelle blague. Si ton chien t’aide pas,
j’aurai même pas besoin d’autant !

nem precisamos de 10 minutos!
Глупец! Если зверёныш лезть не будет,
мы и быстрее управимся!
