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.
I've spent that time trying to 
find where superior spirits live,
قضيتُ ذلك الوقت محاولاً البحث 
،عن مكان عيش الأرواح العليا
Währenddessen hatte ich nach
dem Aufenthaltsort der Naturgeister gesucht.
Pasé ese tiempo
buscando dónde viven los espíritus,
He pasado el mes
buscando dónde viven los espíritus,
Un mois aussi
que je cherche la demeure des esprits,
ho cercato in lungo e in largo 
dove viva la regina degli spiriti,
Nesse tempo, procurei onde
os espíritos superiores vivem,
Всё это время я провёл
в поисках пристанища духов,
