History Manga / WorldsEndHaremFantasia

* BleachedUnderpants: ''[[DownplayedTrope Barely]]''. SAVAN is mostly known as a {{hentai}} artist, and this series is almost as explicit as his previous works, relying on camera angles and whited-out genitals to keep it inside the lines.

* PornWithPlot: Even more so than original-flavor ''Manga/WorldsEndHarem'': like many other Ghost Ship manga, the series is virtually softcore {{hentai}} but with an extensive plot carrying the sexual content.

* TangledFamilyTree: The four counties of Isteshia, Nargala, Garsul, and Enshu are vestiges of the Kingdom of Fafnir, which {{balkanize|Me}}d long ago, and their four ruling houses are all descended from Fafnir's royal family and variously interrelated. ThePatriarch Arges Isteshia is Arc's maternal great-uncle, though Arc refers to him as his grandfather, and Arc's LoveInterest Aurelia is Arges's direct granddaughter, which in turn makes Arc and Aurelia [[KissingCousins second cousins]]. [[spoiler:Arc also infuses Boa Enshu with Macht and has sex with her; how they're related is unclear but presumably somewhat similar.]]

* BalkanizeMe: The counties of Isteshia, Nargala, Enshu, and Garsul are all remnants of the ancient Kingdom of Fafnir, which broke apart along dynastic lines long ago. The four families of the House of Isteshia are all descended from Fafnir's royal family. [[spoiler:Arc ultimately goes to war with his relatives to reunite the kingdom in order to defeat the empire.]]]

* BalkanizeMe: The counties of Isteshia, Nargala, Enshu, and Garsul are all remnants of the ancient Kingdom of Fafnir, which broke apart along dynastic lines long ago. The four families of the House of Isteshia are all descended from Fafnir's royal family.

** {{Downplayed}} afterwards: Arc avoids having vaginal sex with his harem due to [[MysticalPregnancy the heightened risk of pregnancy]], though nearly anything else goes. The exception is Lati, who routinely has vaginal sex with him to adjust his power levels: he hasn't infused her with Macht so the pregnancy risk issue doesn't apply, and presumably as a SexMagic expert she has some form of FantasyContraception anyway.

* FantasyContraception: In volume 6, Felaris eats some nuts that she says will prevent pregnancy, and then insists that Arc finish inside her. [[spoiler:Arc also offers "moon fruit" to Celine in chapter 35 before feeding her his blood and then taking her virginity.]]

* HotterAndSexier: Reito Mizuhara in original-flavor ''Manga/WorldsEndHarem'' was virtually a CelibateHero despite the women throwing themselves at him (because he was trying to save himself for his ChildhoodFriendRomance); the series split its time between him and the more sexually active Shota Doi. ''Fantasia'' focuses on a single male lead, Arc, who has a harem of women who literally have to feed off his magic power by consuming his bodily fluids; the logical results occur.

* FantasyContraception: In volume 6, Felaris eats some nuts that she says will prevent pregnancy, and then insists that Arc finish inside her.

* HerosSlaveHarem: ZigZagged. Once Arc gains the power of Macht, any woman who consumes his blood becomes unable to live without consuming his fluids (sweat, saliva, blood, and semen all work equally well). Lati took it upon herself to kidnap the first couple of women and infuse them without even Arc's consent, and later makes clear that he'll have to continue adding women to his harem or else run the risk of a PhlebotinumOverdose. After Wenna and Cassia, Arc has a HeelRealization about it and starts making sure that anyone else he infuses with Macht is fully informed of the consequences and benefits beforehand and explicitly consents. [[spoiler:But then he backslides when his gambit to take control of House Isteshia from his grandfather requires him to covertly feed his blood to some of his female relatives--though [[GoneHorriblyWrong this backfires on him horribly]] when one woman detects the blood beforehand and the other turns out to be a BlackWidow with a compulsion to kill any man she falls in love with.]]

** Arc gets hit with this one more time, and this time its the biggest one in the series, when he [[spoiler:uses a death curse to try and kill the Crown Prince of the Empire, only for a spell the Prince cast before hand to activate, causing the curse to rebound onto the Prince's wife, and Arc's love, Aurelia, and ([[AmbiguousSituation maybe?]]) kill her instead.]] In this case, however, after a period of mourning, Arc resolves himself to kill the man he truly blames for [[spoiler:Aurelia's death]]; [[spoiler:the Crown Prince]] himself.

* OnlyMostlyDead: {{Implied}}. Prince Deutias claims that [[spoiler:Aurelia]] was killed by the death curse meant for him, but refuses to let any of [[spoiler:her]] relatives see the body and is later shown [[spoiler:preserving her body in a crystal in service to a mysterious prophecy mentioned in the prologue]]. So [[spoiler:Aurelia]] may not actually be dead.

* TangledFamilyTree: The four counties, of which Arc's County of Nargala is one, are vestiges of the Kingdom of Fafnir, which {{balkanize|Me}}d long ago, and their four ruling houses are all descended from Fafnir's royal family and variously interrelated. ThePatriarch Arges Isteshia is Arc's maternal great-uncle, though Arc refers to him as his grandfather, and Arc's LoveInterest Aurelia is Arges's direct granddaughter, which in turn makes Arc and Aurelia [[KissingCousins second cousins]].

** Secondary character "Magical Vir--GIRL Johanna"--her words--is a wizard who has kept her virginity ostensibly to enhance her magic potential. [[VirginShaming She's a little sensitive about it.]]

** {{Justified}} during the year Arc spends preparing for Lati's ritual: one of the conditions is that he abstain from sex, which turns out to be because she needs his male essence to be at the absolute maximum for the ritual to work (apparently riffing on the myth that masturbation reduces male potency).

** Garsul is associated with [[TurtlePower turtles]]. Gidu Garsul is known for speaking ''slowly'', but he's a certified MightyGlacier. Meanwhile his daughter Miu is instead a very powerful BarrierWarrior.

** Arc gets hit with this one more time, and this time its the biggest one in the series, when he [[spoiler:uses a death curse to try and kill the Crown Prince of the Empire, only for a spell the Prince cast before hand to activate, causing the curse to rebound onto the Prince's wife, and Arc's love, Aurelia, and kill her instead.]] In this case, however, after a period of mourning, Arc resolves himself to kill the man he truly blames for [[spoiler:Aurelia's death]]; [[spoiler:the Crown Prince]] himself.
