Kralsei

Kralsei is the non-binary ship between Kris and Ralsei from the Deltarune fandom.

Chapter 1
Ralsei and Kris first meet when Kris and Susie arrive in the Kingdom of Darkness. Ralsei, hidden under a hood, tells the Prophecy of the Delta Rune, after which he reveals more of his appearance. While Susie doesn't believe the prophecy and leaves, Kris stays with Ralsei. Ralsei joins Kris and gives them a tutorial on how to encounter enemies, encouraging pacifism.

Kris and Ralsei continue their journey together, and are not separated from each other for a long time. Eventually, they are joined by Susie, but she later decides to join Lancer as their enemy. Eventually, Ralsei and Kris get both Lancer and Susie in their team (although Lancer keeps enough distance). Lancer later sends the three to jail (this was due to him wanting to avoid having them face his father) and while Susie is in her own jail cell, Ralsei and Kris are in the same cell.

Kris and Ralsei separate after the King is defeated. Before Kris and Susie leave, Ralsei shows his true face and hopes he can see the two again.

Chapter 2 (Spoilers)
Kris and Susie both return to the dark world where Ralsei is waiting for them both. Ralsei surprises them with rooms in his castle. Kris and Susie shortly return to the light world where they have to do a school project together, which results with them going to the library, discovering another dark world in the library's computer lab, and Ralsei returns there.

On the journey, they discover two branching paths. Ralsei asks Kris who he will go with, but no matter the response, Susie insists that he and Ralsei go together on one path, leaving Kris to go on the other path by himself (because road cones block the path that Ralsei and Susie take). He eventually meets Noelle and recruits her.

While in the Queen's Mansion, Susie and Berdly both go on a serperate way to save Noelle (who had to surrender herself to Queen), leaving Kris and Ralsei by theirselves again.

On their lonesome, they come across a giant lake of (battery) acid. Kris pulls a lever that summons a swan boat. They both ride it until they reach their stop. While on the ride, Ralsei will tell Kris about their first encounters, saying that he was nervous about first impressions and that he even hid his face. He's never had a friend before. He then says that it's nice that Susie is Susie, and that Kris is Kris.

Optional

Chapter 1
When discovering a White Ribbon in a chest while in the Field of Hopes and Dreams, Ralsei tells Kris to equip it since it's armor. If Kris instead equips it on Ralsei, he asks while blushing 'if he's cute'.

While fighting the training dummy before entering the Field of Hopes and Dreams, Kris' ACT menu has the option to hug Ralsei, which Ralsei appreciates and blushes from.

If Kris' stands close to Ralsei for a long period of time (face close), Ralsei starts blushing.

Chapter 2
When Noelle is hiding from Queen in a disguise (in a carnival related location) and gives Queen a prize for winning a game but shortly gives the prize to Kris after saying she doesn't want it, Susie and Ralsei suddenly show up. Ralsei asks if the prize is a gift for someone, and Kris is given the choice of giving it to either Susie, Ralsei, Noelle or Berdly.

When Susie and Berdly leave Kris and Ralsei on their own while in Queen's Mansion, Berdly referrs to Ralsei as a "lackey" (which means someone who runs errands for another, or a servile follower). Ralsei asks Kris if he thinks of him as a lackey. If Kris says "Of course", Ralsei will say that he's happy to hear it. If Kris says "Of course not", Ralsei will be suprised and wonder if Kris thinks of him as more than a lackey.

While on the swan boat ride, Ralsei will tell Kris that it's nice spending time alone together like this. If Kris says that he feels the same way, Ralsei will have a huge blush on his face and will say that he's happy to hear it.

While on the swan boat ride when Ralsei is talking about Susie being Susie, and Kris being Kris, Kris has the option to say "It's nice that Ralsei is Ralsei". If he says that, Ralsei will blush and then says that no one has ever said that to him before, and hearing it come from Kris means a lot to him.

Shortly before the swan boat ride ends, a camera is on the sidelines. Ralsei asks Kris if they should pose, and the choices: "Do not pose", "Peace sign", "Rude gesture", and "Hug Ralsei" are shown. If Kris hugs Ralsei (which would be the obvious choice), Ralsei will act surprised and blush while the camera snaps. He asks if the camera really took a picture of that.

Fanon
Like other Deltarune exclusive ships, it does not have massive popularity, and has notably less fanart than Kris or Ralsei alone or Kris, Ralsei and Susie as a team. It is still one of the most popular Deltarune ships.

On AO3, it is the third most written romantic ship and fourth most written overall ship for the Deltarune fandom. It is the most popular romantic ship for both characters involved, as well as the most popular ship for Ralsei and second most popular for Kris (behind the non-romantic ship between Kris and Susie).
