Funbag Fantasy (Kyonyuu Fantasy in Japan) is an H-Game and the first in the titular series, originally releasing in 2008 and receiving an English localization in 2016.
The game follows Lute Hende, who graduates from the Knight Academy with the worst grades of everyone in everything, and is promptly relegated to the far-off land of Boan. He appears doomed to an insignificant existence until he is "attacked" by the succubus Shamsiel, who is stunned when the encounter involves much more pleasure for her and much less death for Lute than she'd expected.
Shamsiel decides to stick around, and with her help Lute foils a rebellious plot by Boan Castle's prefect. As a reward, the king of Edelland offers Lute a more crucial position, and from there Lute takes on a web of political scheming which threatens to bring down the kingdom from the inside, while hopefully picking up a few more lovers.
Funbag Fantasy contains examples of:
- Arranged Marriage: Between Isis and Motaire. The former is dedicated to it, the latter isn't.
- Assassination Attempt: From actual assassins (including series regulars Assassins A, B, & C, making their debut) to the simple poisoned drink, Lute deals with many threats to his life on his journey up the ranks, even ignoring the Uriah Gambits against him. Bernstein is successful in one against King Hagel I as part of his final plan to kill Lute.
- All Women Are Lustful: Seemingly everyone who has sex with Lute will desire him from that point. Comes with Lute being half-incubus. It's why his mother warned him not to touch a woman until he reached adulthood.
- And Your Reward Is Clothes: When Lute is about to see the king for a reward after ending the Boan conspiracy, Shamsiel jokes that her ideal reward would be a bra. Should Lute accept the king's subsequent offer to become army commander, he asks for a "very large" bra in exchange. Shamsiel is ecstatic when Lute unveils her gift.
- Babies Ever After: In the earliest accessible ending, where Lute declines the king's offers and returns to Roxanne in Boan, she is shown to be pregnant in one final scene after a timeskip.
- Big Damn Heroes: Tipped off by Luceria about Lute being framed for murder and his imminent execution, Gladys rushes her soldiers to the capital, with the three generals masking her movements. Her attack diverts the soldiers who are reluctantly about to kill Lute, and Gladys herself blocks the Prime Minister from finishing the job.
- Breast Expansion: Shamsiel experiences a significant one after enough intimacy with Lute.
- Buxom Beauty Standard: Luceria's reputation as the most beautiful woman in Edelland comes in part thanks to her possessing the largest breasts in the kingdom.
- Defeat Means Friendship: Gladys becomes an ally after first losing to Lute in a formal duel where they bet their lives, then later challenging him to a considerably more private & lewd duel and losing once again.
- Divided We Fall: Comes into play in multiple ways, for the struggle against Wackenheim's Inland Rebel Army.
- King Hagel I is wary of rival nations taking advantage of the political fractures exposed by the civil war, but as determined as he is not to let Edelland become a victim of this trope, for five years none of his experienced commanders have been able to quell the rebellion. With options running thin, he approves of Bernstein's suggestion to send Lute; the kid appears to be lucky, and a miracle worker is one thing they haven't tried.
- Prime Minister Bernstein, meanwhile, has been using this trope to his advantage while undermining the king's efforts to unite Edelland and spoil his fun. He has Wan Coan empty the weapons cache and leak strategies to the enemy, to ensure the rebels keep the upper hand and the kingdom remains fractured. Bernstein suggests Lute as commander because he expects Lute to fail miserably and further empower the rebels.
- Gladys, after she's captured, reveals that she and her father supported the Knighted Bureaucracy the whole time, and her father started the rebellion because he wanted to avoid this trope. King Hagel I had made many enemies across the kingdom by pushing his reforms, and letting all of these groups run rampant would fracture Edelland a hundred ways and leave it vulnerable against its neighbors. A figure as respected as Wackenheim inviting them to join him at Vunderbalt prevents the kingdom from being split into more than two pieces and limits the fighting to one front.
- Divorce Requires Death: Once Roxanne refused the divorce her husband demanded upon discovering her family's lack of assets, he isolated her within the castle and concocted a plan where she would be executed for adultery & he would be free. His efforts to push Roxanne and Lute together succeed and they have the affair, but he falls into a coma in the process. Which leaves them right back where they started, except now Roxanne is the one who wants to separate and cannot get approval from her spouse, leaving her stuck until he passes.
- Earn Your Happy Ending: While the VN has many endings, the true ending takes the longest to reach, and includes the most wicked & deranged plot in the entire game. Bernstein kills King Hagel I, plants evidence to incriminate Lute, and locks him in the dungeon while also imprisoning his available allies. It's only thanks to Shamsiel and Luceria escaping to tip off Gladys, and Gladys rushing her troops to the capital with the three generals covering for her, that all of the heroes can escape their final trial unscathed.
- Fantastic Racism: Not nearly as much of a focus as in the sequels and prequels, but present nonetheless. Humans and demons do not get along despite once co-existing, and by the start of the game a war in which humanity claimed victory has confined demonkind almost entirely to the Girapon Woods.
- Fat Bastard: Prince Bobon, the Royal Brat and Manchild who cares only about living in luxury and ruling over everyone. He wants his father to hurry up and die so he can take over.
- Heel–Face Turn: Lute has a knack for turning enemies into allies. Shamsiel, Isis, Motaire, Gladys, and Emeralia each individually make at least one attempt on Lute's life, and by the true end they all look up to him.
- High-Heel–Face Turn: Among Bernstein's known lackeys (Emeralia, Wan Coan, and a portion of the Royal Guard), the only one to defect is Emeralia, the lone woman.
- Honey Trap: One of Emeralia's most reliable methods of eliminating threats. She lures them in with her looks and some calculated softening of her disposition, then magically enhances herself to melt their mind with the ensuing bliss. Her victims don't die, but they become useless at everything.
- Immodest Orgasm: Every woman, every time.
- Impersonation Gambit: In the climax of the first chapter, Lute disguises himself as the traitorous prefect of Boan Castle, to meet with the similarly traitorous Prince Bobon and bait him into revealing the plan to revolt. Lute pulls it off, and Bobon is exiled while Lute is invited to the capital for a more prestigious position.
- Interspecies Romance: Between Lute and Shamsiel. According to Shamsiel, there were and are many more within royal families, which is supported by Princess Luceria being half-nymph. And since Lute is actually half-incubus, every romance of his is a downplayed instance of this trope.
- I Want My Beloved to Be Happy: In the story branch where Isis becomes Lute's bodyguard, she resigns herself to this feeling as she watches Lute's popularity skyrocket and keeps her feelings to herself out of either knightly duty or shame that she's fallen for the one she'd been open about hating. She remains this way forever in the Luceria ending, but fares better in the true ending.
- I Will Wait for You: As Lute departs Boan, if he says he'll find a way to return after travelling to the capital, Roxanne pledges to wait for Lute forever. In one ending Lute comes back almost immediately, but in others he never does. The true ending has Roxanne travel to the capital herself to see Lute less than two months later.
- Love at First Sight: Roxanne admits that she felt something for Lute as soon as she met him largely because he was different from the people she was used to interacting with.Roxanne: (to Lute) "People from the knight academy, they act so elite, so strong. Their mindset that they're amazing, unique... it's so alienating. Just like this man. But you... you were different. You were natural, not eager to prove something. I knew that the moment I met you. And I thought... I wanted to see you again."
- Making Love in All the Wrong Places: Lute and Shamsiel get it on in a church, with Shamsiel scoffing at the idea that they'll face divine punishment. Other locations for sex include: a grassy knoll, a river in a forest, the ground in that forest, a royal audience chamber, a pool, the ground next to that pool, a loggia, and a dungeon.
- Marry Them All: In essence, during the true ending. Lute as King of Edelland officially marries Shamsiel, Roxanne, and Luceria, but also gives Gladys, Isis, and Emeralia pivotal posts in the castle. All of them live together happily.
- Ms. Fanservice: Of course the main heroines all qualify, but past them there's Aristera and Droit, existing solely to be groupies who are beautiful, scantily-dressed, and very lascivious.
- My God, What Have I Done?: Emeralia had become accustomed to secretly carrying out crimes for her father's benefit, but committing regicide, sending the palace into a tailspin with the kingdom soon to follow, turning her only friend against her, and condemning to death a man so innocent that he is not even angry at her, all for the sake of someone who does get angry with her over minutiae, proves to be too much. She breaks down and turns.
- No-Holds-Barred Beatdown: Moltaire receives two. Each occurs after he disparages his superior Lute, in front of someone who's far stronger and respects Lute, and even while apologizing cannot avoid doing it further.
- Out with a Bang: Shamsiel can kill a man simply by having sex with him, and in the weeks before the story begins this trope befalls over half a dozen poor sods in Boan who found her waiting in their rooms. Same goes for Luceria as she is half-nymph, but she is unaware, and her family keeps her secluded in the castle. One of Bernstein's anti-Lute plans involves bringing Lute into contact with Luceria and just waiting for the inevitable romance.
- Porn with Plot: Between all of its branches, the VN clocks in at 20+ hours as Lute steadily rises from last-place Knight Academy graduate living in the boonies to an esteemed individual living in the kingdom capital as he deals with multiple conspiracies and military threats against the kingdom, all while enjoying some hot sex.
- Quit Your Whining: After Lute gets promoted, Motaire continually complains about the unfairness of it all and talks down to Lute despite their respective ranks. Lute isn't bothered, but anyone else in the vicinity will promptly force Motaire to shut up.
- Reassigned to Antarctica: The story opens with Lute being shipped off to the remote territory of Boan, in the hopes that he will just rot away and never influence much of anything. Then Lute meets Shamsiel.
- Romancing the Widow: Should Lute return to Boan, he can officially do this to Roxanne. Their relationship prior to that point is better described as romancing by a woman who wishes she were a widow.
- Samus Is a Girl: Before the player meets Gladys, the "son of Wackenheim", everyone refers to her using her male-sounding nickname. The deception doesn't last long before she makes her first appearance.
- Sex–Face Turn: Justified with Shamsiel, as finding a reliable and durable source of the goods in Lute means that she can get what she wants without consuming anyone else.
- Smart People Play Chess: The rebel commander, in addition to being renowned and feared as a general, is known as the best chess player in the kingdom. Motaire, the top student of Lute's class, also plays.
- Smart People Wear Glasses: Emeralia, who is a teacher and by far the most composed character in the game, is the only one with glasses.
- Take a Third Option: After Lute foils the Boan Prefect's attempt to join the rebellion, the king invites him to the castle and rewards him with an offer to either join the royal guard or become commander of the army. Lute can suggest that he simply returns to Boan and becomes the new prefect. The VN quickly comes to an end if that option is selected, as there is no more adversity to be found there, but Lute is a happy man. He spends his days surrounded by guards and citizens who respect him, and his beautiful wife Roxanne who loves him.
- Teacher/Student Romance: Invoked by Bernstein; Lute is recommended as Luceria's swordplay instructor for the sole purpose of pushing the two of them together.
- Tranquil Fury:
- The demeanor Luceria adopts toward Emeralia after she aids in killing Luceria's father King Hagel and framing Lute for it, once her initial bout of anger and disbelief passes.
Luceria: "I do not wish punishment or insult on you. However, I do not intend to be near you ever again. [...] Do not pretend that you don't know who should rightfully live and who should die."
Emeralia: "...Princess...Please forgive me..."
Luceria: "I will pretend I did not just hear that. I want no apology."- Her response to Motaire willfully not seeing through the charade is just as calm but even more biting.
Luceria: "You have no right to call me your princess. You are an enemy to me. [...] If you want to report what you saw yesterday to the Prime Minister, be my guest. You could not possibly sink any lower in my eyes." - Ugly Guy, Hot Wife: Irboyne (plain-looking middle-aged man) and Roxanne (busty & curvy younger woman).
- Unwanted Spouse: Roxanne, in the VN's first act. Her husband had married her for noble prestige, but turned on her after learning her finances are actually down the drain. He's so desperate to get away from her that he pushes Lute and Roxanne together to get them killed for adultery.
- Uriah Gambit: Bernstein attempts this against Lute in both of the major story branches. In one, he sends Lute to explore the Girapon Woods, which no human has ever returned from, with another knight who both hates Lute and is so frustrated with her engagement that she's become volatile & borderline suicidal. In the other, he makes Lute commander of the army when Lute has no military or leadership experience, and sends him to defeat the Inland Rebel Army alongside three generals who have negative patience for incompetent allies.
- Vapor Wear: Seemingly none of the women wear a bra in their standard outfit.
- Wins by Doing Absolutely Nothing: When Lute & Roxanne first get together, Shamsiel blocks Irboyne from busting them. But the second time, she is nowhere to be found as they trigger his trap and he spots them coupling, which immediately solves their problem as the sight causes Irboyne to fall unconscious and never wake up. Shamsiel claims that she knew from the beginning this would happen and intentionally went to gather info elsewhere.
- World of Buxom: None of the ladies are below an H-cup.
- The Wrongful Heir to the Throne: Prince Bobon is technically next in line for the throne, but virtually everyone is aware that his selfishness and stupidity would drive the kingdom into ruin.
- You Can't Go Home Again: Both endings of the Girapon Woods branch. In one, Lute awakens his full demonic powers and would not be welcome back in Edelland, so Lute & Shamsiel live together in the woods. In the other, Bernstein learns about Lute's demonic heritage and openly orders his death but Isis refuses to kill him, so Lute & Isis flee the kingdom as fugitives and go into hiding together.
- Zero-Approval Gambit: Gladys, like her father before her, leads an army in a military campaign against King Hagel I and his Knighted Bureaucracy, as an enemy of all Edelland. In actuality, both father & daughter always supported the Knighted Bureaucracy, but felt that it was too unpopular among nobles to be implemented without the kingdom falling to pieces. So, they consolidated all opposition under their banner, both to secretly undermine it and to limit the infighting elsewhere, and accepted the label of traitor.
