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.
Master, shall I go and give 
that thing a good chomping?
مولايّ، هل أذهب وأقطّع ذلك الشيء بأنيابي؟
Mein Herr, schickt mich und
ich strecke den Drachen nieder.
Amo, ¿debería ir a darle una mordida?
Amo, ¿debería ir a darle un bocado?
Mon maître, laissez-moi y aller.
Je n’en ferai qu’une bouchée.
Padrone,
Mestre, que tal eu ir e dar
uma bela mordida naquilo?
Хозяин мой, если хотите,
я его одним махом свалю?
