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.
But you lose major points for 
abandoning your composure in battle.
لكن لديك نقطة ضعف رئيسيّة وهي أنّك
تفقد رباطة جأشك في المعركة
Aber im Kampf seine Ruhe zu verlieren,
bringt Punktabzug.
Pero pierde puntos
por dejar la calma en batalla.
Pero pierde puntos
por dejar la calma en batalla.
Mais au combat,
faut savoir garder la tête froide.
Tuttavia, il fatto di perdere il controllo in battaglia
Mas perdeu muitos pontos por
abandonar a compostura na batalha.
Однако то, что во время боя
он теряет хладнокровие — минус.
