Funbag Fantasy: Sideboob Story 2 (Kyonyuu Fantasy Gaiden 2 in Japan) is an H-Game and the second sequel to the original game in the Funbag Fantasy series, releasing in 2013 and receiving an English localization in 2020.
Five years after the previous game's events, Lute has suddenly vanished from Edelland, sending the palace into a panic as they frantically look for him while attempting to run the kingdom without him. They also must not let his absence become public knowledge, as rival kingdoms Iberia and Ostacia are ready to pounce on any perceived weaknesses, but allied kingdoms are feeling more and more slighted as their requests for an audience with Lute go unanswered.
Across the sea, in Hillsland, a candid masked man washes up on shore with no memories. When he attempts to ask for directions, he is arrested as he'd failed to notice that he was completely naked, and in prison his cellmates give him the name Mask. After escaping & hiding out on what seemed to be a pirate ship, he befriends the mermaid princess Rosalyn and becomes wrapped up in the internal & external political conflict overwhelming Hillsland.
Funbag Fantasy: Sideboob Story 2 contains examples of:
- Amnesia Episode: The entire first half is one, as Lute loses his memories to a cursed mask and wakes up in foreign territory. While he tries to find his way out of about five layers of trouble, everyone in Shoenburg's palace is in despair over his disappearance and working to find him before other nations realize he's gone.
- Bag of Spilling: The previous Sideboob Story averted the trope, having begun where the first game left off with Lute as king and surrounded by the allies he'd made, but not this one. Lute starts Sideboob Story 2 in an even worse position than he was in at the beginning of the original game, as back then he'd been a graduate of the Knight Academy with an official post. Now, he's in prison with no possessions sans a mask and no friends.
- Bedmate Reveal: Once Shamsiel finally finds Lute in Hillsland. Lute/Mask wakes up to Shamsiel giving him a titjob.
- Boob-Based Gag: A gorgon fails to petrify Lute because he keeps looking at her breasts instead of her face.
- Call-Back: Shamsiel reveals to the rest of the cast that she is Shaharl's daughter, as Funbag Fantasy 2 established. Rosalyn, a newcomer and mermaid, is a descendant of Lorelia from the same game.
- Continuity Nod: Many, as the first two acts are set in Hillsland where Funbag Fantasy 2 takes place 200 years prior.
- Downer Beginning: The first scene consists of Lute washing up on an island nation with no memories and being thrown in jail for his trouble.
- Earn Your Happy Ending: Unlike the first Sideboob Story where Lute begins in the favorable position he'd reached in the original game's ending, Sideboob Story 2 has Lute start off with nothing once again.
- Exactly What It Says on the Tin: The Mask of Amnesia is a mask that causes amnesia.
- Gaiden Game: Averted, despite the Japanese title calling it one and the English title keeping the implication. It's a direct sequel to the direct sequel to the original game.
- Heartbroken Badass: While everyone in Shoenburg mourns Lute's absence, Shamsiel takes it the hardest. Her proud and cheeky nature is completely absent for the first two acts, replaced by despondence as she circles Edelland over and over again looking for Lute.
- Hot Consort: Shamsiel, Roxanne, Luceria, and Gladys for Lute. Serebria for Emperador II.
- Love Across Battlelines: Serebria knew that she'd eventually marry a hallowed demon, but didn't expect it to be the king of the nation hers had just gone to war against.
- Naked Apron: Roxanne, in the alternate ending midway through the VN.
- Naked on Arrival: Lute in the beginning, sans the mask. He is arrested.
- No-Sell: When Legrande attempts to assassinate Lute, Shamsiel, Gladys, and Aphrodia by sucking them into a soul jar and trap them for eternity, Lute simply pops back out, shocking the spoiled prince. Lute then proceeds to pull out the other three ladies just as easily.
- O.O.C. Is Serious Business: After months of fruitlessly searching for her love, Shamsiel is so broken that she visits the cathedral in Bustenhalter, genuflects, and can't stop sobbing as she prays to see Lute again.
- Porn with Plot: A plot spanning an entire continent, with plenty of lethal political maneuvering and intense physical warfare to go around. And even more sex as Lute now has a whopping eleven big-breasted ladies to have sex with.
- "The Reason You Suck" Speech: Gladys angrily reams into Legrand how his actions have caused a needless war claiming many innocent lives, calling him a pathetic excuse for a prince. Legrand, however, doesn't take her seriously and laughs it off, even when she demands he takes measures to atone for the kingdoms he's caused damage to, mockingly and insincerely saying he will. Then Shamsiel takes her shot by bluntly asking why Rosalyn dumped his sorry ass, which takes him completely off-guard. Shamsiel then proceeds to gleefully insult Legrand that Rosalyn had tossed him aside like trash in favor of Lute and he'll never be even half the man he is. She drives it further by saying that as a succubus, she can tell Legrand would be lousy in bed anyway, which also gets a laugh out of Gladys. Legrand gets enraged enough that he plotted to murder them both for daring to hurt his fragile ego.
- Royal Harem: Four official consorts and three unofficial consorts reside in Shoenburg Palace with Lute. And then there are the four other rulers he's married by the true ending.
- Royals Who Actually Do Something: Nearly all of the named characters are royals.
- Running Gag: Minor villains still have their names mispronounced on a regular basis, and Assassins A, B, & C are still useless at everything.
- Taken for Granite: Happens to anyone who looks at the gorgon statue’s face. In one ending, this fate befalls Emperador II.
- Too Spicy for Yog-Sothoth: In the first act, Hillsland is having problems with a minotaur which devours people's desires and causes their heads to melt. When the government sends a bunch of prisoners including Lute to die fighting it, his lust proves to be so great that the minotaur cannot endure all of it. Unfortunately for the minotaur, even after attempting to stop eating it, Lute's lust continues to flow on its own until the minotaur explodes.
- World of Buxom: While the not-so-busty generic maids return from Funbag Fantasy 2, they appear even less often this time around, so the huge busts of named female characters continue to dominate the screentime.
