Kimihitos erster Gast im Inter-Arten-Austausch ist ein Fabelwesen namens Mia. Mia hat einen üppigen weiblichen Oberkörper und den Unterkörper einer Schlange. Für Kimihito ist das eine sehr reizvolle Kombination.
Kimihito wakes up to find Miia crushing him in her sleep. After escaping, he draws a bath for her to warm up and goes to make breakfast. In the kitchen he is surprised by Smith, who has come to make sure he isn't engaging in any prohibited activities with Miia, such as sex. After Smith leaves, Miia tries to seduce him, only to accidentally dislocate his shoulder. The two go on a field trip, including a visit to an all-species lingerie shop. Afterwards, they run into a racist couple who harass Miia, and Kimihito has to jump in the way when she tries to strike them with her tail, to keep her from breaking the law. Trying to escape from a curious crowd, they hide in a love hotel, where they are ambushed by the Interspecies Exchange Security Squad. However, Smith recognizes them and fixes the situation. Leaving the hotel, they encounter the couple, and when they begin harassing Miia again Kimihito punches them. At home, Miia resumes her advances on Kimihito, only for them to be interrupted by Smith.
