Ep. 10: Mai y Misaki buscan un OVNI en un tren, donde se encuentran con una mujer que afirma ser una princesa alienígena.

10

After seeing a broadcast on UFOs, Mai and Misaki go by train to try and see one for themselves. On the long train ride, they meet a strange woman names Beebee, who claims to be an alien princess, and tells the siblings that the UFO has actually been looking for her. On the journey back, a sudden electrical storm causes the train to stop indefinitely, and a fight breaks out between some women on the train. Mai transforms into Emi to try and keep the peace, and manages to catch a glimpse into who Beebee really is: a singer who got stage fright and lost her confidence, giving up on her dream. As Emi, Mai reminds her that everyone gets stage fright, and encourages her. Later on, Beebee returns to Tokyo to continue chasing her dream, and Toppo reveals that the "UFO" was actually another one of his kind. (Source: Wikipedia)
