Ralsei and Kris (deltarune)

Ralsei deeply cares about Kris. He wants to befriend Kris in order to create the trio of heroes mentioned in the prophecy, which he wishes to fulfill. Ralsei is very respectful and friendly to Kris, even to the point of offering to fan Kris with a leaf like a servant or pretending that he is okay with being hit. Even if Kris acts rudely towards Ralsei, he won't be offended by them, and may even blame himself. Ralsei also appears to be easily embarrassed or intimated by Kris as it's easy for Kris to make him blush, as seen when Kris stands close to him. They are a duo for the half of Chapter 1, before Susie changes her ways and joins them again. However, several occasions in chapters 3 and 4 reveal they do genuinely care for Ralsei, as they are driven to such as when they consider taking Ralsei as a partner towards the festival or the possibility of hugging him during chapters 2 and 4 (in the latter doing so without asking the player) and calling him "cute" in chapter 3, although due to Kris's personality it is ambiguous to whether they still consider Ralsei a platonic friend or if they also have romantic feelings for him. Despite his similarities to Asriel, Kris considers Ralsei quite different.

Kris and Ralsei work together throughout Deltarune, including several times the two are separated from the rest of the party. Ralsei likes Kris very much and sees them as a friend though occasionally makes flirtatious adjacent comments, and at one point asking if Kris was going to propose to him in Chapter 2 upon seeing the Snow Ring. However, it's implied that Kris doesn't consider Ralsei as close as Susie, as his Tea only heals 60HP (although Noelle's, who is a childhood friend, only heals 10HP more) to them. They have more moments with each other during Chapter 2 and spend more time as a team of two when Susie temporarily splits up from them.

In Chapter 3, Ralsei expresses his regret and guilt at not being able to be there for Kris in the Light World, and even asks Kris if they could buy something from the festival for Susie and pretend it's from him, showing how much he trusts Kris.

In a Dark World, Kris's entire appearance transforms, making them resemble a knight. Kris dons silver armor: shoulder pauldrons, a cuirass, gauntlets, and boots. They wear a navy blue bodysuit underneath the set, and a pink cape drapes across their right shoulder. Finally, Kris's skin changes to cyan, and their hair transits to navy. The shading for their skin is also used for their cape, giving the illusion of blue stripes in a few of their sprites.
