The Reveal: Yuko is now married, and trying to hide her otaku side gig from her mother in law.
Shout-Out: This episoded mentions an old anime called "Ninja Cap-tan", which is a reference to a real-life Toku show produced by Toei in 1976 called Ninja Captor (Which, depending on who you ask, may or may not have been considered an installment of the Sentai series at one time, possibly making this a Discontinuity Nod).
Wholesome Crossdresser: In the ending, Nobuo dresses up as a female character from an in-universe anime series. Though, said character is an altered version of one of the male characters from Ninja Captor.
You Answered Your Own Question: Akagi bemoans not being told about Yuko getting married, as he would’ve stated a Fake Kidnapping at the wedding. Everyone then tells him that he wasn’t told or invited for precisely that reason.
