The Dive System (ダイブシステム, , Daibu Shisutemu^?) is a revolutionary communication technology that converts human consciousness into data, allowing individuals to directly enter a network-based virtual world. This system provides an experience that is indistinguishable from reality, making it one of the most advanced technological achievements of its time.

Developed by Dr. Arisugawa, the Dive System was instrumental in the creation of the Magical Gate, a vast virtual theme park where children from around the world can interact and explore freely. Through this technology, users can fully immerse themselves in a digital environment, blurring the line between the real and virtual worlds.
