Bian

Private Bian is a soldier serving in the Royal Army.

He's part of 7th regiment of the Royal Army's Border Patrol Garrison and he's participating in the Martial Arts Competition in Grancel together with his commanding officer and two fellow soldiers from the same division. (the competition used to be restricted to members of the army and more an evaluation of soldiers' skills than a public event)

He and his team make it through the preliminaries and are introduced in the waiting room where the participants of the blue side wait for their turn to do battle. While acknowledging that the competing teams are fierce, he nevertheless still maintains a positive attitude about his team's participation, but unfortunately he and his fellow squad members are pitted against the much stronger Intelligence Division's special ops team led by 2nd Lieutenant Lorence.

Bian and his fellow soldiers don't get a lot of opportunity to show their skills during the match as the special ops take the initiative and leave them reeling from their opening attacks. He manages to get one fairly ineffective shot in at his attacker, but before he has a chance to strike again, Lorence rushes in and fells him and two of his teammates with a single slash from his sword, leaving Bian's initial attacker and the other special ops to beat his commanding officer into submission.
