Everyday Life with Threatening Letters.
The girls are shocked when it appears that Kimihito is going on a date with Ms. Smith. Miia, Papi, Cerea, Mero and Suu immediately begin following them, first to a maid cafe (where Mero disguises herself as one of the maids, using Suu as a uniform), then to an arcade (where Papi is disguised as a cosplayer), then to an ice cream truck (where Miia and Cerea impersonate servers), but they fail each time. Finally, Miia follows Kimihito and Ms. Smith to a love hotel, where she meets up with Rachnera (who has been trailing them all along). Rachnera tries to sneak into Ms. Smith and Kimihito's room but is hindered by Miia, causing them to be grabbed by the MON Squad. Ms. Smith explains that Kimihito had received a threatening letter from someone named "D", and their "date" was actually a ploy to lure the culprit out. Since they failed to do so, Ms. Smith asks all the girls to go on dates with Kimihito. Kimihito's first date is with Miia (with Mero in tow, much to Miia's annoyance); they go to an aquarium where Mero is treated like royalty. Upset that Kimihito seems to be paying more attention to Mero, Miia storms off, only to bump into a reptilian liminal, a Dragonewt named Draco, who takes her out on a boat where he attempts to sexually assault her. Kimihito (with some help from Mero) rescues Miia and inadvertently exposes Draco as actually being a female. While Draco did not write the letter, Ms. Smith arrests her for being out without her host family.
