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 war breaks out, we can 
kill the guys who control us
إذا اندلعت حرب، يمكننا قتل من يتحكّم بنا
Sollte ein Krieg ausbrechen,
Si hay una guerra,
Si hay una guerra,
Si une guerre éclate, on aura peut-être
l’occasion de tuer nos maîtres
In caso di guerra,
Se entrarmos em guerra,
Если разразится война…
