Dive to the Heart is a location that appears in Kingdom Hearts, Kingdom Hearts Final Mix, Kingdom Hearts II, Kingdom Hearts II Final Mix, Kingdom Hearts coded, Kingdom Hearts Re:coded, Kingdom Hearts Birth by Sleep, Kingdom Hearts Birth by Sleep Final Mix, Kingdom Hearts 3D: Dream Drop Distance and Kingdom Hearts III.

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 that occur within it have a real effect on the waking world, and in two instances they are actually observed by outside forces.[1]

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.[2]

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
