Haseo
The protagonist of the series, and a newbie within The World R:2. Haseo had an encounter with PKers (Player Killers) before joining the Twilight Brigade. He is an outsider in real life, and not very good at dealing with people. He appears to be obsessed with Ovan's enigmatic nature, which he soon discovers isn't so unusual.
Ovan
The Guildmaster of the Twilight Brigade, Ovan has some strange device sealed around his left arm. He is an enigma to those who know him. Many people think he is odd, due in large part to his search for the Key of the Twilight, an item that may not exist.
Shino
One of the few people close to Ovan who acts as leader of the Twilight Brigade whenever Ovan is incapable of doing so. Gentle-mannered but strong-minded, she holds the Twilight Brigade together during Ovan's frequent absences. She and Ovan seem to have a more involved relationship than mere guildmates.
Sakisaka
Sakisaka left another guild to join the Twilight Brigade and was a member during its previous incarnation, he often helps beginners like Haseo and a lot more with Tabby to level up. He is skeptical that the Key of the Twilight even exists and often complains that the Twilight Brigade's search is meaningless. He quit the Twilight Brigade after Ovan's disappearance, assuming Ovan had stolen the Key of the Twilight for himself, and formed a Guild with Tabby.
Tabby
As her name implies, Tabby somewhat resembles a cat, with feline ears, claws, and hair that acts like a cat's tail. Her weapon of choice is a pair of large cat paws that she uses to slash at enemies. Tabby has been playing about as long as Haseo and usually fights alongside Sakisaka in the field. She often refers to Sakisaka as her "master" or "teacher." She is loyal, friendly and positive.
