In Great Sage's recollection, all seems to be smooth sailing for Tempest... but then the oldest of the Demon Lords, Milim Nava, arrives! Rimuru, as Milim's bestie, is appointed by the majority to be in charge of keeping an eye on her. With no knowledge of this, Milim explores Tempest and interacts more with the residents of the city of monsters... and Rigurd keeps track of all the damage she causes along the way in a report for Rimuru. "Rigurd... are you angry?"
Lady Milim certainly is 
quite the free spirit.
تتمتّع ميليم-ساما بروح حُرّة حقّاً
Meisterin Milim liebt schon ihre Freiheit.
La señora Milim vive
libre de preocupaciones.
La señora Milim vive
libre de preocupaciones.
Tout de même, dame Millim
n’en fait vraiment qu’à sa tête.
Certo che la Grande Milim
è proprio uno spirito libero.
E vejo que Milim-sama é uma
pessoa de liberdade estravagante.
Однако ж… Княжна Милим
буквально олицетворяет свободу.
