Saluna

Saluna is the femslash ship between Luna Loud and Sam Sharp from The Loud House fandom.

Canon
In "L is for Love" (S2E23), Luna is revealed to have a crush on a girl named Sam, whom the audience is initially led to believe is a boy. Throughout the episode, she is hesitant about giving a token of her affection to Sam, and eventually places a love letter in Sam's locker at the end of the episode. It is then revealed to the audience that Sam is actually a girl, which in turn reveals that Luna is apparently bisexual (meaning that she's sexually attracted to both men and women).

In "Friendzy" (S3E19), in a dispute over privileges with her siblings, Sam is the first of her many friends she invites to her place in order to gain special privileges.

In "Racing Hearts" (S3E45), Luna and Sam participate in the Royal Woods Astonishing Quest. Initially, Luna believes the two of them would be perfect partners together. However, as they progress through various challenges, they begin to realize how much less they have in common, even when Luna takes Lori's advice to embrace Sam's interests so she can better understand her. On the final challenge, they learn they do have something in common, which is their lack of interest in baking. Despite the fact they didn't win, they brush it off, saying that even if they don't have much in common, they want to spend time together so they can discover new things they like together.

In "Deep Cuts" (S4E29), Sam protests alongside Luna and their bandmates to save their music club.

In "Purrfect Gig" (S4E32), Sam helps Luna catsit the McBride's cats. After being paid for their hard work, Sam gives her half of the money to Luna so that she can buy a VIP Pass to Mick Swagger's concert, much to Luna's happiness, who kisses her on the cheek and hugs her as affection and thanks.

In "Snoop's On" (S4E48), Sam helps Luna get Leni, Luan, and Lincoln to confess that they had been reading Luna's diary by dressing up as a girl named Roxy, who Luna had written about in her fake stories, and going around town with Luna in order to fool the siblings.

In "Undercover Mom" (S5E16), Luna refers to Sam as her girlfriend and laments that they got into an argument over a song.

In "Lori Days" (S5E36), Luna has a movie date with Sam before being interrupted by Lori.

In the comic "Sam's Pick" (printed in Live Life Loud!), Luna and Sam spend the day jamming throughout the Loud house and then exchange their guitar picks. The next day, Luna thinks she has lost Sam's pick and tries to distract Sam while her siblings look for it. When they couldn't find it and Sam asks why she's been acting nuts, Luna admits that she lost her pick. But Sam reveals that she put both picks inside Luna's guitar case to make sure they wouldn't lose them. With the pick found and all is forgiven, Luna performs in the attic for her siblings with Sam.

In the comic "Midnight Melody" (printed in After Dark), Luna was staying up at midnight after being struck by inspiration to write a song for Sam. As she struggles with finding the right word that rhymes with "world", she decides to call Sam for advice (while fearing she may be asleep, that she'll think that Luna is a weirdo or both). Fortunately, when Luna does call her, Sam was up binge-watching a new cooking competition show. As Luna confides to her with her rhyming issue, Sam explains that she's had the same problem and figured it would be "more punk" to make lyrics that don't rhyme and as long as they come from the heart, that's all that matters. Thanks to her advice, Luna was able to finish the song.

In Loud and Proud, the girls attend a concert, but keep missing their favorite bands. They eventually get covered in mud and Flippees and end up playing onstage as "The Muddy Flippees".

Fanon
The pairing is well-liked and widely praised amongst the Loud House fandom, which began to gain momentum following the episode "Racing Hearts" as it showed there was more to Sam's character besides playing the guitar and being into rock music like Luna. The particular episode was also praised for showing a narrative which managed to demonstrate some key differences between the two girls in terms of personality, talents, and interests. Fans of the pairing also love how understanding Luna and Sam are towards one another when one dismisses the other's interest as something they don't like, as well as how accepting they are of each other's differences.
