A dictionary consultation tells me that the title of the book might mean something like "older brother introduction manual"... I don't know what that's supposed to mean, so there's a good chance I'm misunderstanding. Maybe it refers to a real book with a similar title or something?

"Aniki" refers to Gachimuchi/Billy Herrington. Some comments interpreted it as a Yaranaika reference or a Cho Aniki reference, since it's slightly vague.
(Also, the book title is changed from the Twitter version of this pic where it was "thin book")
