Kite was invited by his real life friend Yasuhiko to play an online game called The World. Orca, Yasuhiko's character, and Kite adventured in a dungeon where they encountered a mysterious girl named Aura. Aura was going to give Orca a mysterious book until a monster called Skeith appeared and killed Orca. Skeith was about to attack Kite as well, but a mysterious hacker named Helba saved Kite and booting him from the server with the book. After the encounter, Kite learned that his friend Yasuhiko had fallen into a coma in the real world. This prompted Kite to investigate The World thinking it may be related to their encounter with Skeith, which soon turn out to be a bigger crisis that he had ever thought.
