A sprawling, persistent online universe, it allows you to take on any role, to scale any mountain.
BT, the standoffish wavemaster (a kind of magic-user) whose belief that actions in The World are reflective of unrealized real-life fantasies ends up clashing with her own sense of self.
Sora, an incredibly believable troll brought to life through consistent backstabbing and occasional complaints about his mom.
Crim, whose determination to maintain a separation between his physical and digital selves acts as a weirdly appropriate counterpoint to the way he inspires his more emotionally invested friends.
And Subaru, the girl whose strange bond with Tsukasa ends up giving both of them the strength to pursue their convictions.
This slow build is reflective of one of the show's core narrative issues - leaving too much ambiguous for too long.
