Ep. 18: Yuuko visits a coffee shop, encounters a costumed Mai, and learns about Mio's past in a dream.
Yuuko takes Mio to a reopened coffee shop, expecting confusion, but flees crying upon realizing Mio understands the menu. Ms. Nakamura prepares a stronger drug for Nano but accidentally consumes it herself. Misato reprimands Koujirou for neglecting cleaning duties, yet blushes when he agrees to comply. Yuuko travels to a fast food restaurant in another town to meet Mai, but misunderstandings lead to her being laughed at by Misato's younger sister, who is also there. Upon finally meeting Mai, Yuuko is shocked to see her in a knight costume and expresses a desire to go trick-or-treating, despite Halloween being over a week ago. The Professor demonstrates a biscuit-powered robot named "Biscuit 2" to Nano and Sakamoto, who remain unimpressed. Additionally, Yuuko experiences another dream about the Fey Kingdom that reveals the origin of Mio's fuzzy pigtails.
