Tsukasa’s inability to log out of the world worries Mimiru. The Crimson Knights, on the other hand, see Tsukasa as a threat.

BT and Sora suspect that Tsukasa is somehow connected to a very important artifact, the Key of the Twilight.

Tsukasa's rampaging Guardian monster wreaks havoc in The World, and an edict from Subaru makes him a wanted man.

Tsukasa finally tames his Guardian monster, but unbeknownst to him, someone is plotting his capture.

Subaru carefully observes Tsukasa, gradually getting to know him. Sora mounts a rescue mission.

Mimiru encounters a novice player and offers her guidance in The World. This new relationship helps Mimiru uncover her own motivation for playing.

Mimiru extends Tsukasa an invitation to meet; BT and Crim share an interesting encounter.

An elite hacker proves instrumental in the quest for the Key of the Twilight, and Tsukasa gets stuck with a sick Grunty.

Bear's shortcomings as a father may be the root of his concern for Tsukasa. Clues arise as the search for the Key of the Twilight continues.

Mimiru, Bear, and Tsukasa join forces before embarking on a non-fighting quest.
