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.
Oh! So if I go there, 
can I meet superior spirits?
إذاً إن ذهبتُ إلى هناك، يمكنني اللّقاء
بأرواح عليا؟
Oh! Da finde ich also
hochrangige Naturgeister?
Oh! Então, indo a esse lugar,
encontro espíritos superiores?
О-о! И там я смогу встретиться
с высшими духами?
