Red String Of Fate - Television Tropes & Idioms

A common concept, especially in series dealing with romances, is the Red String of Fate (akai ito or unmei no akai ito). The concept is that two people who are destined to be together are attached by an invisible red string bound to their pinky finger (generally, though not always, at the first knuckle from the fingernail).

It is an East Asian belief originating from Chinese legend, with people claiming many different countries of origin and/or religions for it, but the usage is clear regardless. The trope is so pervasive that merely holding up the pinky finger is used as shorthand for girlfriend/mistress/significant other.

Akai Ito (written with the kanji kanojo no chi, or "The Girl's Blood", given the reading of akai ito in furigana) is also the title of a 2004 Dating Sim by Success. The actual red string concept figures into some of the art as well as the story.

The real question is: If it's invisible, how do we know it's red?

Warning: Choking Hazard. May be related to the Pinky Swear. Usually involved in Reincarnation Romance.
