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.
Everyone needs a break sometimes.
فالجميع بحاجة لاستراحة من وقت لآخر
Todos necesitan un descanso.
De tanto en tanto hay que descansar.
Ogni tanto prendersi una pausa fa bene.
É bom descansar de vez em quando.
Полезно иногда отдохнуть!
