"Prophecy" is the fourth and latest chapter of Deltarune, first released on June 4, 2025, alongside Chapter 3, as a paid purchase. Both were released as a Nintendo Switch 2 launch title the next day.
This chapter sees the heroes exploring the Dark Sanctuaries, a set of three Dark Worlds created in the town church, learning more about the Legend of Delta Rune as they attempt to stop the Knight. This chapter notably takes a darker and more serious character than the previous ones, evidenced by moments such as the Weird Route progressing, disturbing revelations about the Legend, and the first appearance of a Titan.
Back in TV World, Kris and Susie are about to seal the Dark Fountain. Susie ponders about the Roaring Knight, but then tells Kris to seal the fountain quickly. However, before we see Kris do so, it cuts to the Dreemurr residence in the Light World, where Toriel is waking Kris up for breakfast. During breakfast, Toriel invites Susie to go to church with her and Kris, which she reluctantly accepts. However, when she tries to leave, she remembers how the Knight took Undyne to the bunker, which is close to the church. Therefore, some people at the church may know how to get in.
After church services, Susie has Kris ask the churchgoers about the bunker, while she helps herself to drinks. Kris learns from Alphys and Noelle that the Mayor (Noelle's mother) keeps important info at her home, therefore she is their best link. After reporting back to Susie with the information, Susie manages to get Noelle to invite her and Kris over under the guise of studying for their school projects. When they leave the church, Kris’ father, Asgore, attempts to give Toriel some flowers. However, Toriel leaves, asking if they can talk later, so he gives them to Kris.
Later, at Noelle’s house, Susie distracts Noelle, while Kris searches the Holiday house for clues. In Noelle’s absent sister Dess’ room, they find the code in her guitar. But before the player can read the code, Kris suddenly rips their SOUL out of their body and hides it away. The player-controlled SOUL escapes and travels through the air ducts. In the kitchen, we can see Kris on a call with a mysterious person, who warns them that Susie must not get the guitar. In the bathroom, Kris’ father, Asgore (who is apparently cleaning) can be seen in the bathroom and a bedroom, discussing a black shard he has, and how he can get Toriel to believe him about something, and get the family back together before Asriel comes home.
Eventually, the SOUL makes it to the basement and shuts off the power, leading Susie and Noelle there. When the SOUL (under an angel decoration) startles Susie and Noelle, they capture it and take it to the living room. When the two leave, it escapes to Dess’ room, only to be attacked by Kris when it comes near Dess’ guitar. However, the noise made attracts Susie and Noelle, causing Kris to hide themself and their SOUL in the closet. The SOUL makes its way to the guitar again, but Kris attacks it, making more noise. Susie investigates the closet, berates Kris for making so much noise, and grabs the guitar. When Noelle sees Susie with the guitar, she reluctantly asks her to play it, and they leave. After they do so, Kris puts the SOUL back in their body, and contacts their caller, who says they’ll “be right there.”

In the living room, Susie is playing the guitar, when Asgore arrives, saying that Noelle’s mother is about to be home, much to her surprise, and she tells Susie to put the guitar away. Sure enough, her mother, Carol, shows up right after, and upon seeing Susie with Dess’ guitar, grabs it from her, and sends Noelle to the kitchen. When Susie tries to explain, she just demands that she leave, while also telling her not to talk to her daughter again. Before Susie leaves though, she decides she’ll be taking Noelle to the festival tomorrow, to spite Carol. Carol also tells Asgore, who has been eating from the snack tray this whole time, to do it outside. When Kris leaves, Carol confronts them, apologizing for what just happened, and reassures that they are welcome to the Holiday home anytime.
Outside, after she and Kris talk to Asgore for a bit, Susie reveals that she saw the code in Dess’ guitar, but couldn’t memorize it. Still without the code, Kris and Susie are ready to call it a day, and head to Kris's house. However, the door is locked, so they decide to ask Toriel, who is , only to find it now contains a Dark World. When they go inside, they see the Knight and Kris gives chase, but their efforts fail (if Kris does reach the Knight, they just do nothing). After a fall, they reunite with Ralsei. Susie is attempting to practice her healing magic on Kris's injuries, but Ralsei restores them back to normal, and the three set out to explore the Dark World once again.
This Dark World has stained glass pieces explaining the Legend of Delta Rune. As Ralsei explains, everything the prophecy says will come true, with the first few detailing the Roaring. The Delta Warriors then encounter an old man. Susie reluctantly agrees to help him, mistaking him for a Lightner who got stuck in the Dark World. The Old Man proves to be more competent than he seems, and the group safely make it to his study. Throughout the Dark World, the Old Man manages to give Susie more confidence in her healing powers, and she thanks him for being the only one who was able to teach her properly.
Before the Delta Warriors leave the Old Man’s study to seal the Fountain, he asks Susie to take his letter with her. After another encounter with the Knight, the Fountain is sealed, Kris and Susie wind up in the church late at night, and find that there is another Dark World in main congregation room, which is locked.
They head into Father Alvin's office, and Susie makes a surprising discovery in his desk drawers: a glass case of dust with an axe in it, and a photo of the Old Man. Turns out, the Old Man was really Alvin’s late father, Gerson Boom, meaning the Gerson in the Dark World must’ve been the Darkner form of his ashes. Additionally, Susie's letter to Alvin has made it into the real world, telling him that his father was proud of him and to follow his hopes and dreams. Without a way to get in the congregation room, Susie gets the idea to create her own Dark Fountain and get in through that Dark World. Remembering what Queen said back in Chapter 2, she borrows Kris’ knife and stabs the floor with it, successfully creating a Dark World. However, this second Sanctuary isn’t exactly the same. Exploring the sanctuary, the Delta Warriors learn more about the Prophecy: the three heroes are the Prince, the Cage, and the Girl.
When they are about to read how to save the worlds, however, the glass is suddenly shattered by a figure resembling Gerson. Susie gives chase, ending up in pitch-black darkness. When she lights it up with her healing powers, she only sees a monstrous face. Ralsei destroys the being and explains that one of Gerson's statues from his study came to life and became hostile, and that Darkners based on memories of loved ones only appear in specific darknesses. Susie berates Ralsei for not telling them earlier, and Ralsei admits that he has been hiding things of the prophecy in order to not upset Susie. They reconcile, with Ralsei promising to be more honest, and Susie admitting that she doesn't care how the prophecy ends, because whatever it is, they'll do it together.
After the 2nd Sanctuary's Fountain is sealed, Kris and Susie return to the Light World and unlock the main door to enter the 3rd Sanctuary, where they encounter the Knight, who proceeds to make another Fountain within the darkness. This Fountain solidifies, and inside of it comes the harbinger of the Roaring, a Titan. Ralsei instructs the team to climb it, as it won’t attack itself. As a being that is incapable of reason, there's only one solution: FIGHTing. After defeating its spawn, the Delta Warriors eventually reach the top, where the Titan has been waiting. They take it on, but they only damage the outside, and the Titan regenerates. Suddenly, Gerson appears, to help defeat Titan for good. Susie decides to throw Kris inside the Titan, where their SOUL manages to destroy the Titan for good.
After Susie asks Kris about that “red heart thing,” she realizes she has to talk to Gerson, and rushes ahead. Ralsei, realizing Susie will see the end of the prophecy, rushes to stop her, but it’s too late; Susie shatters the glass. When Ralsei questions her, she laughs at it, saying it's stupid because none of them would ever let it happen. Realizing that he was unable to change the outcome of the prophecy and that Susie took it well, Ralsei breaks down crying. Kris motivates Ralsei that they need to be like Susie and continue, even in the face of whatever may happen.
Kris and Susie wake up in the congregation room at twilight. No closer to opening the bunker, they head to Kris’ house, where they find Toriel partying and dancing with Sans, their new neighbor, in the living room, prompting Susie to leave. Later that night, Kris, with their SOUL in a birdcage, is struggling to sleep, attempting to shut out the noise downstairs. Eventually, they decide to escape through the window, but they receive a phone call from the same person from before, telling them not to forget something they “promised.”
After the credits, the Voice from Chapter 1 compliments the player for attaining the halfway mark, but states that "it is still waiting. How much longer now? My Deltarune.”
If the player did the Weird Route in Chapter 2, instead of Susie and Kris asking if they can come over, Noelle will approach the two and invite them over to her house after church. There, after Kris rips out their SOUL, she asks Kris if they can talk privately in her room. If the SOUL goes to the vent in Noelle’s room, the player can overhear a conversation between Kris and Noelle, where it is revealed that during the previous night, Kris took Berdly to the hospital and visited Noelle. During their visit, Kris claimed the Dark World was just a prank and removed a thorn (the Thorn Ring's form in the Light World), from her hand. When a choice prompt appears, the SOUL ends up in the room, and retakes control of Kris. Upon selecting "Proceed" as a reply to Noelle's question, the player can move towards Kris to control them. Aborting the route here will set the game back on the normal route, starting from Susie and Noelle's hangout on the couch and Kris in the kitchen after returning the SOUL to the gift box. If the player takes too long to repossess Kris while Noelle is talking, Kris will eventually notice it, grab Noelle's arm, and hurry out of the room. After a moment, Kris will return and to take the SOUL back to the gift room. If the player responds "Me" to Noelle's question, the scene will continue. If the player chooses "..." during this question or "Sorry, just a prank" during the next few questions, the scene will abort.
Eventually, the player will force Noelle to equip the Thorn Ring, locking in the route for the chapter. The screen will turn black as a small, unknown red dot the same color as Kris's SOUL appears where the Thorn Ring is located, sprouting thorns before fading away. Afterwards, Kris goes to the bathroom, where they furiously throw the SOUL in a trash can and kick it, before Asgore tells them that Carol is having everyone leave the house.After Kris leaves the house with Susie and Asgore, the snack plate that Asgore would be eating from and Kris would help Susie finish in the normal route is absent. Instead, Asgore shows concern for Kris and hands them a Hot Chocolate before promptly leaving.
While walking away from the Holiday household and through town, new pieces of dialogue from Susie are present. She states that she found the guitar with the code to the shelter inside of it, but Asgore started talking to her while she was carrying it and she couldn't memorize the code before Carol arrived home, lamenting on how poorly that study session went, including all three of them not being able to hang out. Nearing the church, Susie recalls how Noelle wanted to talk to Kris privately but points out how "something... about her look was kinda... weird." She asks what Kris and Noelle were talking about. The scene will suddenly freeze and gain a sepia-like reddish filter. A dialogue box for the player to choose among four blank options appears at the top of the screen. When the player attempts to confirm one of the options, the scene abruptly resumes with Susie jokingly wondering to Kris if the conversation was about her. After a brief moment, she assures Kris that she won't bring up the subject again, implying that Kris told her not to during that moment.
The rest of the chapter continues relatively unchanged, but with some slight differences:
When Ralsei asks if the player would like to close their eyes and imagine what Susie could be doing, upon declining multiple times, a new option to think about Noelle appears. When choosing to think about Noelle, the same red dot from the scene in Noelle's room faintly appears with the shaky text "Thank you..." slowly drawing before the screen flashes red and Susie shakes Kris awake.
Back in the Light World, the player has the option to pray for someone in the church. If you choose to pray for Noelle, Kris angrily kicks the candle stand, to Susie’s surprise.
At the end of the chapter, if you tell Ralsei that it’s okay not to smile, Ralsei tea will now heal 100 HP as opposed to the regular 60 HP even though all teas turn into rotten tea.
At the end of the chapter, Kris doesn't attempt to leave the house, instead remaining in bed with their phone. They recieve a call [presumably from Carol), asking if they're going to the festival, ominously stating that Noelle is "really looking forward to seeing [them]."
When the scene fades to black, the red dot from earlier cutscenes appears right after.
This is the first chapter to feature SAVE points in the Light World.
It is also the first where the heroes explore more than one Dark World.
This chapter's opening title is unique compared to previous ones. It features a glimmering blue background within the logo, the same seen on the "prophecy glass" seen throughout the Sanctuaries, while a portion of "Neverending Night" plays, before the logo shatters into glass-like pieces.
This is also the first opening to feature music.
Changes[]
In the initial release of Chapter 4, the Weird Route had a short animation of a rose losing its petals after the SOUL forces Kris to put the Thorn Ring back on Noelle’s finger. Many interpreted this as the SOUL forcing Kris to sexually assault Noelle, given that "deflowering" is often taken as a term for a "loss of virginity.” Two days after the chapter'srelease, Toby hastily removed it in an update, replaced it with an ominous glowing red pixel, before replacing that with sprouting thorns in the next patch.
