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.
If you manage to beat her, 
I'll call you "Boss" from now on.
إن تمكّنت من هزيمتها، سأدعوك "زعيم" من الآن فصاعداً
Wenn Myuran verlieren sollte,
nenne ich dich ab sofort Meister.
Si ganaras por algún milagro,
empezaré a llamarte jefe.
Si ganaras por algún milagro,
empezaré a llamarte jefe.
Si jamais tu la bats,
je reconnaîtrai ta supériorité !
Se sconfiggerai Myuran, 
d'ora in poi ti chiamerò "capo".
Se por acaso a Myulan perder,
eu te chamo de "meu líder".
Если одолеешь Мюлан —
 буду звать тебя «старшой».
