Beast modifies his usual "It's lunchtime!" to "It's breakfast time!" since his fight with Medusa occurs in the morning.
Apparently Haruto cast a Connect spell off camera to get donuts (without Shunpei even noticing).
Rinko finds Misa's profile on her computer. It reveals that her birthdate is June 11, 1992 (Heisei Year 4). Her real full name is Inamori Misa (稲森美紗).
The interesting thing is that the computer says that she was 16 at the time (the age of the actual actress), but her birthdate was in 1992, so she would have to be 21 years old today. If they want her to be 16, she should have been born in 96-97 (Heisei 8-9).
Father's name was ?Shinji 真治 (45 years old) and mother was Sayuri 紗由里 (40 years old), they're both noted as being missing.
The big reveal of the episode is that Misa has a twin little sister named Inamori Mayu. They drop a clue for this beforehand with Mayu's figure on her bag, which displays a four member family, two parents and two sisters.
The use of twins is also a big part of how magicians perform magical acts, so it makes sense for this trope to appear in Wizard.
Misa and Mayu both take parts of their name from their parents Shinji(?Masaharu?) and Sayuri.
Misa means "beautiful gossamer" while Mayu means "true reason". Misa tends to wear a fine shawl, so it makes sense.
