Heroes on quests are common. Sometimes, TheHero's motivation for pursuing the quest derives from his regard for some sort of idealized woman. Not uncommonly, this lady is the hero's love interest, and he is striving in order to be able to marry her. His love for her is pure and strong and overcomes all temptations that are thrown into his path.

The lady herself often occupies an exalted role: she is a goddess, a saint, a queen, a princess, or something similar. Generally, she is very pure, sometimes to the point of seeming unapproachable. If she is unmarried, she is chaste. She is also often a ProperLady. If it's not just the fact that she's inspirational, but that he feels like she's above him, she's a PeerlessLoveInterest.

The lady can be the one who gives the hero his quest; he then departs to complete it before returning to her. Alternatively, she flits in and out of the hero's path, reminding him of her presence but staying out of reach. Occasionally, she is at his side all along, serving as a reminder of what he is striving for and inspiring him to persevere. In all situations, she often dispenses advice to the hero, although that advice can be rather cryptic.

This trope is particularly common in works from the medieval and Renaissance period, as it ties closely to the ideas of the CourtlyLove tradition. In older works, it often takes the form of [[LadyAndKnight a knight errant and his lady love]].

Compare to TheObiWan, TheLostLenore, ManicPixieDreamGirl, and MenActWomenAre. Called "Meeting With The Goddess" in Joseph Campbell's ''[[HerosJourney The Hero With A Thousand Faces]]''.

[[folder:Anime and Manga]]

She is extremely kind and idealistic, and Vash treats her lessons and worldviews as sacred.
* Miu in ''HistorysStrongestDiscipleKenichi''. She's the granddaughter of the WorldsStrongestMan, and she's ''[[CantCatchUp always]]'' been a better martial artist than Kenichi, who makes it his goal to be strong enough to protect her.

* Bioware games tend to have one good female character as a romantic option for the PlayerCharacter, and they tend to get upset with you if you do something ForTheEvulz.
