A young wavemaster, only known by the alias of Tsukasa, wakes up in an MMORPG called The World, with slight amnesia. He does not know what he has previously done before he woke up. In The World, he is suspected to be a hacker of the Crimson Knights, as he was seen accompanying a tweaked character in the form of a cat. Unable to log out from the game, he wanders around looking for answers, avoiding the knights and other players he meets along the way. As Tsukasa explores The World, he stumbles upon a magical item that takes the form of a 'guardian', which promises him protection from all harm. Subaru, the leader of the Crimson Knights, along with several other players who became acquainted with Tsukasa, set out to investigate why Tsukasa is unable to log out, and attempt to get to the bottom of the problem before it gets out of hand.

While playing the newly released MMORPG ‘The World’, Minase Mai and Tomonari Kasumi collapsed in the real world and were sent to the hospital after hearing a mysterious sound. Only Mai had recovered while her friend Kasumi had slipped into a mysterious coma. Mai is later approached by the creator of ‘The World’, Tokuoka Junichiro, who unveils to her that, just like her friend, six other players across the country had also collapsed while playing ‘The World’ and are now in mysterious comas. What exactly is ‘The World’, what is this mysterious sound Mai keeps on hearing, and why are people slipping into comas from this game? Minase, Junichiro and their acquaintances set off to get to the bottom of this problem before any further harm happens.

Somewhere in the MMORPG called ‘The World’, a group is gathered at a pub, awaiting the start of an event. There, old friends and acquaintances are reunited, including those who rarely log on. Some are even forging new relationships for the first time. Together, invited by the hacker Helba, the group leaves for the event in the Net Slums where a celebration awaits them all.

Soon after, mysterious monsters appeared, and death by these monsters caused players to slip into a coma in the real world.
