Magazines are recurring items in the Final Fantasy series. In the vast majority of occurrences the magazines are of pornographic nature, and are only found as an Easter Egg and bear no relevance to the plot.
In the North American releases, some magazines were either renamed due to censorship, or removed from the game completely.
The Magazine (エッチな本, Etchi na Hon?, lit. "H book"), also known as Playboy, Playboy Magazine, Smut, PornoMag, Penthouse, or Lustful Lali-Ho, is an item heavily implied being pornographic in nature and the screen turns pink when the player reads it. It can only be obtained in the Developer's Office, which was not included in the initial American release, meaning the magazine could not be obtained.
The magazine serves a purpose in the Nintendo DS version; after getting a copy, placing it on a stool in the Developer's Room causes it to be confiscated, one of the requirements for getting the Reach Augment. There are, in fact, multiple pornographic magazines in the DS version: the Lustful Lali-ho found in the Dwarven Castle, and the Ninja Sutra, several of which can be found in Eblan. The player can use it in battle, but it will not do anything. It is apparently Cecil's favorite magazine.
Cecil is not the only character who can read the magazine; since any character can be in the lead, any playable character (except for Tellah) can read it at any point in the game.
In The After Years, many dirty magazine copies can be obtained. If the player fights the Game Designer in the Developer's Room after giving it a Lustful Lali-Ho, they will sometimes receive a Discovery Book, an item that increases a character's max MP by 50.
In the library at Castle Surgate, if the player chooses the bookcase before the "A" file, Bartz will say "A..., as..., aha!... Hey, this is about donkeys!" Lenna will reply "Er... Bartz, what were you looking for?", and he will respond "uh? Nothing, nothing at all!" implying Bartz was looking for an adult book (he was presumable looking up the word "Ass", which can either mean Donkey or Rear End/Butt).
"Bushido in the Bedroom" (also referred to as "Book of Secrets") is an item found at Mt. Zozo in the World of Ruin, when the party encounters Cyan. Along with guides for understanding and operating machinery, the player finds the book in Cyan's trunk.
Before the release of Final Fantasy VI Advance the item was merely called "Book of Secrets" and the game shed no light on the nature of its contents. With the release of the GBA version it is implied the "secrets" refers to advice on sex.
Included with the International Version's special fourth disc is a large collection of various background items seen during the course of the game. "H-Books" is an adult magazine from Corel Prison, "Ecchi Manga" is an adult magazine from Junon, and what appears to be a gay theme magazine is from the Honey Bee Inn.
Weapons Monthly, Pet Pals, Combat King, and Occult Fan are series of magazines that give players information on remodeling weapons, teaching limit breaks to Rinoa and Zell, and hints to optional sidequests respectively.
Laguna also used to work as a journalist and many of his articles were published in Timber Maniacs, a magazine that has since ceased publishing due to being viewed too controversial due to its openly political nature. Other magazines mentioned in name only are Battle Series, found scattered on the Timber Maniacs building's floor, to which Squall comments he has read them all, and Anarchist Monthly, of which some paper clippings can be read on a notice board in the Forest Owls' base.
There is a Key Item called The Girl Next Door that can be traded to Zone in exchange for either 25,000 gil or a Rename Card and Shiva's card. It is described in the menu as "A naughty magazine" and can be found in Timber Maniacs building. If the player attempts to purchase one in Timber they get told they are not of age. Irvine also appears to have a stash of his own, as he leaves a magazine for Squall and Rinoa in the "secret spot" he has prepared for them.
