A good chunk of this episode features Mio investigating Marie’s parents, trying to suss out whether or not the letter from Marie’s little brother is legit. We get to see Kyros’s head maid don many faces, and even perform her own stunts. After all, what sort of anime prince, lord, duke or what have you doesn’t have a super maid who can do it all? And even though Marie’s parents try their best to hide their duplicity (well, not really), ace detective Mio sees through it all quite easily. Again, what a super maid!
