The night before the Opening Festival, Rimuru throws a lavish banquet for all the nobles and royalty visiting Tempest. When the party is in full swing, Empress Elmesia of the Sorcerous Dynasty of Thalion arrives, throwing everyone into chaos.
You were waiting for me 
to realize my mistake...
...كنتِ تنتظرينني حتّى أدرك خطئي
Sie hat gewartet, bis ich
meinen Fehler einsehe.
Elle attendait que je me rende compte
de mon erreur.
Stavate pazientemente aspettando
Fez o favor de esperar até que
eu percebesse meu erro...
Вы всё это время ждали,
когда я пойму свою ошибку?!
