Fantastic Romance

**This page needs visual enhancement.**
You can help All The Tropes by finding a high-quality image or video to illustrate the topic of this page.

For romances that not only involve the use of fantastic plot elements, but are literally impossible to pull off unless one or both parties are chronically defying the laws of physics, traveling through time, reality warping, dimension hopping, or defying culturally accepted norms and standards regarding the mingling of fantastic, non-fantastic, or other fantastic races.

If a character is Trapped in Another World and then gets embroiled in such a romance, they often end up saying I Choose to Stay. If they are forced apart, or decide to return to their own worlds, then they are Star-Crossed Lovers. They may still get a Doppelganger Replacement Love Interest back at home. Such relationships often result in the creation of a Half-Human Hybrid.

Compare Magical Girlfriend and Interspecies Romance.

Examples of Fantastic Romance include:

Anime and Manga

Vision of Escaflowne.
In Fushigi Yuugi, Miaka and Tamahome.
Eureka Seven has this as the driving force between the two leads.
In Inuyasha, Inuyasha and Kagome.
In RahXephon, one of these drives the entire plot.
- To explain further (massive spoilers ahead): Ayato and Haruka were middle-school sweethearts, but the impenetrable Tokyo Jupiter field went up while she was on vacation, trapping him inside and her out when they're fourteen. Thanks to the field's time-dilation effects, three years pass for him and fifteen for her. Thus, Haruka is twelve years older than him when she manages to rescue him from Tokyo. Furthermore, he has lost all memory of her (and technically isn't even human anymore). She, however, has spent the whole time pining for him. Eventually, he once again falls in love with her, and that love drives him to use his Humongous Mecha's full potential and become a god. In the end, he recreates the world so that the two of them can be together.
- The fact that it is heavily influenced by the short story The Dandelion Girl helps explain a lot.
In Voices of a Distant Star, the teenaged romantic leads are separated by Faster-Than-Light Travel, so that by the end, the 15-year-old girl's text messages aren't received by her boyfriend until he's 24 and beginning to move on. It is every bit as heartbreaking as it sounds.

Homestuck has a few, but probably the most fantastic and romantic of them all is John/Vriska. They are different species and from different universes, she can communicate with him at any point in his timeline, and they first interact when she tries to mentor him to become stronger so they can defeat the game on whom the fate of the world depends which they are all playing.
