Role: The silent protagonist and leader of the party. Species: Human. Personality: Quiet, mysterious, and difficult to read. Kris rarely speaks directly, allowing the player to guide most of their actions. Despite this, they have their own emotions and motives that occasionally emerge. Combat Style: A balanced fighter who uses a sword. They can attack, defend, ACT to solve encounters peacefully, and use supportive magic later in the game. Notable Traits: Kris has one of the biggest mysteries in Deltarune surrounding their connection to the player's SOUL and the world's deeper secrets.

Role: The prince of the Dark World. Species: Darkner. Personality: Gentle, polite, optimistic, and endlessly supportive. He believes almost everyone deserves kindness and redemption. Combat Style: Mage and healer. Uses scarves instead of weapons and specializes in healing, pacifying enemies, and support spells. Notable Traits: Ralsei knows much more about the prophecy and the Dark Worlds than he initially reveals, making him one of the game's most mysterious allies despite his cheerful demeanor.

Role: The party's powerhouse. Species: Monster (dragon/reptilian-like). Personality: Loud, intimidating, sarcastic, and initially selfish. She starts as a bully but develops into a fiercely loyal friend who genuinely cares about her teammates. Combat Style: Heavy melee attacker wielding a giant axe. She specializes in high damage and offensive magic like Rude Buster. Notable Traits: Susie has one of the strongest character arcs in the game, transforming from an antagonist into one of the group's emotional anchors.

Noelle Holiday is a shy, kind-hearted reindeer monster and one of Kris and Susie's classmates. Though nervous and lacking confidence, she's intelligent, caring, and willing to help others. In Chapter 2, she temporarily joins the party as a powerful ice mage, using healing and support spells alongside offensive ice magic. Noelle has a crush on Susie and is a longtime friend of Kris. Her story is one of the game's most emotional, as her growth—or manipulation—depends heavily on the player's choices. Beneath her timid exterior lies remarkable magical talent and quiet inner strength, making her one of Deltarune's most important supporting characters.
