Tempest is preparing a feast in celebration of Rimuru's return home. Then a newcomer, the majin Myulan, arrives to scope out Tempest on the Demon Lord Clayman's orders, having joined up with Youm's crew as their military advisor in order to enter the nation. Upon arriving, she's surprised to see what a strong nation it is, but continues to talk with its citizens to learn more. Meanwhile, the king of Falmuth, who sees Tempest as a nuisance, conspires with the Western Holy Church in a plot to invade the monster nation.
You said if we kept our grades up, 
you'd show us the rest of that manga!
قلتَ أنّنا إذا حافظنا على علاماتنا عالية
فإنّك ستُقرئنا بقيّة تلك المانغا
Wenn wir gute Noten haben, wollten Sie
uns verraten, wie der Manga weitergeht!
Ben oui !
Ci avevi detto che ci avresti fatto leggere il seguito 
di quei manga, se i nostri esami fossero andati bene!
Disse que nos deixaria ler a continuação
do mangá se tirássemos notas boas!
Вы ж обещали, если подтянем оценки —
подкинете продолжение манги!
