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.
So, I'm Rimuru, and I'll be 
your teacher starting today.
حسناً، اسمي ريمورو وسأكون معلّمكم
اعتباراً من اليوم
Also ich bin Rimuru.
Ab heute bin ich euer Lehrer.
Bueno, yo soy Rimuru
y seré su instructor desde ahora.
Bueno, yo soy Rimuru

Итак, с сегодняшнего дня
я ваш учитель, а звать меня Римуру.
