A Love Interest that at the same time manifests aspects of the archetypal sage, a wise man/woman, or a spiritually enlightened one; he or she may give the protagonist profound pieces of advice in between lovemaking.
This trope is actually Older Than Dirt, and in the earliest versions of it, it was almost Always Female: women were often seen as possessing some "natural wisdom" lacked by males (the "Witch" stock character in fairy tales is believed to descend from this "wise woman" archetype). Modern works feature Love Interests of both genders.
May overlap with Manic Pixie Dream Girl, when the Love Interest is both wise and quirky. Also overlaps with Sexy Mentor and Mentor Ship, when the Love Interest actively takes part in the protagonist's tutelage.
- In Mobile Suit Gundam SEED, Lacus Clyne is this for both Athrun (her original fiance) and Kira (her eventual boyfriend). While not a fighter like them, she has an incredibly sharp mind and knowledge of human nature way beyond her age, which allows her to successfully sort out the conflicted messes that are Athrun and Kira's respective beliefs and motivations in the second half of the series.
- Neytiri from Avatar likewise represents the "natural wisdom" (the New Age version of it), and educates Jake on the beliefs of Pandora natives.
- Naomi Schwartz from The Last Mimzy is this to her boyfriend Larry White, with her Eastern mysticism and New Agey philosophy.
- Izzy from The Fountain was a tragic example of this for her husband Tommy.
- A number of Slavic fairy tales, including the Tale of Peter and Fevronia, have the archetype of the "wise maiden" who speaks in riddles, possesses supernatural powers and eventually marries the protagonist.
- Umberto Eco was apparently very fond of this trope:
- The first Vampirocracy novel shows a budding relationship between main character Leon and Wicca healer Amy. The latter provides Leon with sage personal advice throughout the book.
- In Stargirl, the titular character becomes sort of an Eccentric Mentor for the protagonist. She teaches him many things, like meditating Zen style, and has a profound impact on his life.
- Zigzagged with Princess Zelda across The Legend of Zelda franchise. In games like Ocarina of Time and Twilight Princess, she is a Wise Beyond Her Years girl who explains much of the mythology of Hyrule and backstory of recent events to Link. In games like Skyward Sword and Breath of the Wild, in contrast, she isn't portrayed as being noticeably wiser or more mature than Link.
- Dillion to Senua in Hellblade: Senua's Sacrifice. His advice and support are instrumental in her development, and his defining trait outside his kindness is his level-headed rationality (in contrast to the mostly much more superstitious cast).
