The Dive to the Heart is a location which appears in Kingdom Hearts, Kingdom Hearts II, Kingdom Hearts coded, Kingdom Hearts Birth by Sleep and their respective remakes. It is framed as a world within a dream, and its nature as the dreamer's heart is reinforced by the background music, the gameplay tutorial, and the strange way of speaking used by those within it (a manner also used by the remembered characters of Kingdom Hearts: Chain of Memories). However, the events which occur within it have a real effect on the waking world, and in two instances they are actually observed by outside forces. In terms of gameplay, the purpose of the Dive to the Heart is to serve as a tutorial level, where the player will learn the controls of the game, choose how their character will grow, and fight their first boss. The player is guided through the Dive to the Heart by an inaudible, unseen "voice", whose identity is uncertain.
To reinforce the dreamlike setting of the Dive to the Heart, Sora, Roxas, and Ventus each reach it by falling into an ocean. However, instead of drowning they find that they can breathe, and land upon an ocean floor which erupts into doves, revealing the Dive to the Heart. In Roxas's case, this first Dive to the Heart is merely a memory of Sora's, and he enters his true dive three days later. The Dive to the Heart is composed of several enormous, illuminated stained-glass pillars known as "Stations", rising from unseen depths. Each Station has a unique shade, depicts a specific set of characters, and has its own specific part in the tutorial. In the first game, there is an additional area of the Dive to the Heart based on the Destiny Islands. The background music, "Dive Into the Heart (Destati)", initially begins quietly and hard to hear, but grows in intensity as Sora or Roxas approach the final pillar, where they fight a manifestation of the darkness within them. At the end of their battle with the creature the Dive to the Heart is consumed by the darkness emanating from it, dragging Sora or Roxas with it, but they either wake up or are rescued.
Sora's Dive to the Heart was originally set to return as part of Kingdom Hearts: Chain of Memories, but was removed from the final game.
In Kingdom HeartsEdit
Chronologically, Ventus's Dive to the Heart, here named "Ventus's Mind", is the first to be seen, appearing incomplete due to his broken heart. It is here that Ventus comes in contact with the newborn Sora's heart, and his Station is restored. Ventus does not return to the Dive to the Heart until he involuntarily fuses with Vanitas, his pillar changing appearance with the sudden presence of darkness in his heart, and is renamed "Soul World".
Ventus's Station is quite similar to Roxas's, but features a sleeping Ventus, without his Wayward Wind, at the Keyblade Graveyard, rather than Sora, with his Kingdom Key, at the Destiny Islands. The inner circle of emblems, which usually contains images of the sleeper's loved ones, only contains a stylized fleur-de-lis, which also appears on the edges of the pillar. When Ventus is fused with Vanitas, Ventus's Station is modified - Vanitas himself now appears opposite Ventus, and both have their Keyblades. Half of the outer ring of symbols is replaced with the Unversed emblem, while the other half is replaced with the Mark of Mastery emblem. The field of the Keyblade Graveyard is now filled with the abandoned Keyblades. The inner circle of emblems is replaced with silhouettes of Keychains for the χ-blade, the Wayward Wind, and the Void Gear. After Ven defeats Vanitas, his station changes to a form similar to its original appearance, with some modifications. Ventus is now holding the Wayward Wind and wearing both his Keyblade Armor pauldron and his silver Mark of Mastery charm, while the outer circle of emblems is filled with the Mark of Mastery emblem and the inner circle of emblems is filled with his friends' Wayfinders, signifying that he has regained control of his completed heart.
After the tutorial chapter, the player enters another Dive to the Heart, where they can choose whether to continue the story with Terra, Ventus, or Aqua. This Station displays the trio's Wayfinders, but is purely a gameplay mechanic.
After Ventus's body is placed within the Chamber of Waking, his heart connects with that of a young Sora, who appears in his own Dive to the Heart, named "Sora's Mind". His Station displays the landscape of Destiny Islands on the bottom, with Paopu Fruits and different elements found on or around the island encircled separately on the top.
In Sora's dream, he falls from the sky into the sea below with his eyes closed and slowly descends onto the ground with abyss surrounding him. As he steps into the ground, the darkness below his feet starts to transform into birds and fly away, showing a radiant light that slowly forms into a circle. Each of the Stations in Sora's later Dive to the Heart illustrates one or more of the Princesses of Heart, as well as the characters related to them. The four that are clearly depicted are asleep, perhaps signifying their comatose state in Hollow Bastion.
The first pillar, shaded green, depicts Snow White, the Seven Dwarfs, the forest animals, and The Queen in her hag form. While Snow White is asleep, all the other characters are depicted as awake.
The second pillar, shaded violet, depicts a sleeping Cinderella.
The fourth pillar, shaded red, depicts a sleeping Aurora and silhouettes of Flora, Fauna, and Merryweather, and the silhouette Maleficent makes when vanishing into green fire. This Station is named Awakening.
On the first pillar, Sora is asked to walk, then is shown three weapons, the Dream Sword, the Dream Shield, and the Dream Rod. He is directed to choose one and discard another, and his choice determines his specialty, initial stats, and ability growth throughout the game. After choosing, the Station shatters and Sora falls to the second pillar, where he first encounters Shadows, and is taught about battling and its rewards. The Station then sinks into darkness, and Sora awakens on the third pillar, where he is taught how to examine and interact with objects. By opening a treasure chest, moving a crate, and destroying a barrel, he materializes a door that leads to a dream version of Destiny Islands, where Sora meets facsimiles of his friends, Tidus, Wakka, and Selphie, which ask him enigmatic questions that determine how he gains experience throughout the game.
On the fourth pillar, Sora is again attacked by Shadows, but after defeating them the first Save Point is revealed, as well as floating steps to the final pillar. However, the steps vanish as he climbs them, trapping him on the fifth pillar. As he approaches a strange light, his shadow grows and becomes his Darkside; though he fights it, its darkness swallows him, and he reawakens on the Destiny Islands.
The door reappears, this time on Destiny Islands, when the island is attacked by the Heartless, revealing that it is in fact the world's Keyhole. It reappears a final time with the false Destiny Islands at the Final Rest within End of the World, but this time contains the final confrontation with Ansem, Seeker of Darkness, and Kingdom Hearts itself.
Kingdom Hearts IIEdit
On the third day of his story, Roxas encounters a Dusk in the Sandlot and is sucked into his Dive to the Heart. Like Sora's, Roxas's Dive to the Heart consists of five stained glass pillars, but each of these depict the same image of Sora, Riku, Kairi, Donald Duck, and Goofy at the Destiny Islands, and the pillars are divided between only three Stations. Sora's eyes are closed, showing that he is asleep, while Kairi and Riku's are open, showing that they are awake; strangely, Donald and Goofy's eyes are still open, even though they are asleep as well.
Roxas awakens on the Station of Serenity, where he chooses between the Dream Sword, Dream Shield, and Dream Rod. While this choice determines the order in which he learns abilities as before, the weapon he chooses is immediately transformed into the Kingdom Key (This is different than in the original Kingdom Hearts Dive to the Heart as he does not have to give anything up in exchange for his weapon). He goes through a door to the Station of Calling, consisting of three pillars shaded blue, green, and red and connected by floating stairs. Here, he encounters Dusks and learns about Reaction Commands and treasures. Going through another door, he enters the Station of Awakening, and finds an apparition of himself in his black coat which soon becomes his Twilight Thorn. Similar to Sora's Dive to the Heart, after defeating the Twilight Thorn, Roxas and his Dive to the Heart are consumed by darkness, but unlike Sora, Roxas is rescued by Naminé at the last minute.
Much later, as Sora approaches Memory's Skyscraper, Roxas reawakens inside him and takes him to the Station of Awakening, where they battle and come to peace with each other. This arena is replicated in the Garden of Assemblage for the fight against Roxas's Replica Data.
Kingdom Hearts codedEdit
Data-Sora manifests in a digital version of the Dive to the Heart that is virtually the same as the real Sora's dive. He spots Data-Roxas, but does not recognize him before he disappears, and later mistakes him for Data-Riku. Sora is given the choice to choose between the Dream Sword, Dream Shield, or Dream Rod and which one he is willing to forfeit. However, due to Chip and Dale's reprogramming, the Dream weapons immediately change into the Keyblade, as in Roxas's dive. After fighting off an ambush by a swarm of Shadows, Data-Sora enters the same door that Sora did in his own dive, but this door leads directly to the "real" Destiny Islands, rather than a dream version.
