Leokumi

Leokumi is the slash ship between Leo and Takumi from the Fire Emblem fandom.

Canon
Throughout the Birthright and Conquest routes, Leo and Takumi appear as enemies, and neither seem to acknowledge each other throughout these two routes. They do, however, serve as foils to each other, similar to the other sibling pairs.

In the Revelation route, the two are allies- although neither seem to like each other very much. In their C support, Leo says they'll never be friends, and Takumi agrees. However, in their B support, they both express anger over others (likely their siblings) comparing them to each other, before finding out that they have similar interests (and once again, saying they'll never be friends). In their A support, this attitude seems to have changed completely, as Leo lent Takumi a book while Takumi taught Leo how to make his favorite food (miso soup). They admit that they're now friends, and Takumi considers their friendship proof that Hoshidans and Nohrians can get along, and he says that Leo has made him realize that peace between the two countries after all (implying that everything that happens in Revelation before the player gets their A-Support failed to convince him).

In the Japanese version of their B support, Leo says their relationship shouldn't end with just friendship, and Takumi agrees.

Fanon
Leokumi is one of the most popular in the Fire Emblem Fates fandom, having a significantly larger number of fanfics on Ao3 than any other ship under the Fates fandom tag (beating out Azurrin, which is in second place, by around 370 fics) and easily the most popular ship for both Leo and Takumi. The ship is popular because of the interactions between the two in Revelation and especially their supports, with their A-support showing that they've become incredibly close.

A fanmade S-Support between the two was uploaded by YouTuber Unassuming Venusaur, as part of their Gay Fates Hack (a mod for the game that lets the player get S-Supports between same-sex pairings that aren't Corrin + Niles and Corrin + Rhajat), and it's amassed over 100k views.
