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.
The Queen of Spirits we once 
served passed away long ago.
ملكة الأرواح التي كنّا نخدمها رحلَتْ
منذ وقت طويل جداً
Die Königin der Naturgeister, der wir dienten,
ist vor langer Zeit von uns gegangen.
La Reina de los Espíritus
a la que servíamos
La Reina de los Espíritus
a la que servíamos
La Reine des esprits
que nous servions autrefois
La regina degli spiriti a cui prestavamo servizio
A Rainha dos Espíritos a quem servíamos
faleceu tempos atrás.
Королева духов, которой мы служили…
довольно давно почила.
