|“||Okudera and Koarai from Azuma Unit aren't so strong alone, but in a short-distance team combat, they're as good as my unit. With these two in the team, they can take down various high level opponents. And best of all, Azuma Unit has the old leader of the best A-Rank Unit, No. 1 Sniper: Haruaki Azuma.||”|
|Tsuneyuki Okudera||Noboru Koarai|
The unit's uniform consists of a dark teal jacket with black stripes running through the sleeves and around the collar and also around the edges of the jacket, black pants, and brown boots. The jacket also has a pocket on the right chest, the unit's emblem on the left chest, and Border's emblem on each shoulder.
Azuma Unit is sent to fight off Trion Warriors when they encounter a Rabbit. The Rabbit proceeds to easily defeat Koarai and Okudera, so Azuma shoots them before they can be captured. The other B-Rank teams come to support Azuma, when they are confronted by Lamvanein. Lamvanein's superior firepower causes him to have an initial advantage over the B-Rank teams. Azuma decides that if the battle were to become arbitrary gunfight, Lamvanein would emerge victorious. However, the arrival of Izumi, Yoneya, and Midorikawa allows the B-Rank teams to fight him and eventually win.
