Haya Kittaka/Plot

Background
Kittaka opted for a design track in high school. She was popular among boys from other courses, but due to her consuming passion for anime characters, her suitors were always shot down. At some point she joined Border and became the Operator of Ōji Unit. She designed the uniforms, but due to their reflecting her obsession with anime boys, Kazuki Kurauchi stepped in to make them less extravagant.

Introduction Arc
Ōji Unit presumably takes part in the extermination of all Rads in Mikado City.

Large-Scale Invasion Arc
Ōji Unit is seemingly not deployed during the Second Large-Scale Invasion, and could, therefore, be among the B-rank units with missing members which Masafumi Shinoda prevents from fighting against Aftokrator's forces out of fear of capture.

Round Two
During the four-way rank battle of the day division on February 5, Ōji Unit faces off against Azuma Unit, Katori Unit and Yuba Unit. The three units manage to force Haruaki Azuma to bail out by focusing their fire on him.

Round Three
On Saturday February 8, Ōji Unit fights in the day division of rank battles against Katori Unit and at least one other team, ranking fourth at the end of the match.

Round Four
Since Tamakoma Second fights Ninomiya Unit, Kageura Unit and Azuma Unit in the night division of rank battles on February 15, and since Katori Unit and all other possible opponents were in the middle tier of B-rank or lower, Ōji Unit must have fought in the day division against Ikoma Unit and Yuba Unit. After the scores from both divisions are tallied, Ōji Unit remains in fourth place.

Galopoula's Blitz
Since Azuma Unit, Kageura Unit, and Yuba Unit fight in the night division of rank battles on February 19, Ōji Unit must have competed in the day division against Ninomiya Unit, Ikoma Unit and Suzunari First. They rank fourth at the end of the match. That same night, Ōji Unit and Ikoma Unit are deployed to intercept opponents west and south of the base in preparation of Galopoula's incursion.

Round Five (Night)
After the results of the night division are tallied, Ōji Unit is overtaken by Tamakoma Second and pushed to fifth place.

Round Six
On Saturday February 22, Ōji Unit fights Tamakoma Second and Ikoma Unit in the day division of rank battles. In the meeting before the start of the match Kazuaki Ōji announces his decision to select Cityscape A as the map, and after he details his reasoning she agrees with his choice of a simple stage and silently listens to the strategy he proposes. When the match begins and Kurauchi is defeated, Kittaka charts an escape route for her surviving teammates based on the presumed blind spots of Chika Amatori and Kōji Oki. The match is eventually won by Tamakoma Second, with Ōji Unit scoring a total of three points.

Round Seven
Since Tamakoma Second faces off against Kageura Unit, Azuma Unit, and Suzunari First in the day division of rank battles on March 1, it can be inferred that Ōji Unit competes against Ikoma Unit and Ninomiya Unit in the night division.

Round Eight
On March 5, Ōji Unit faces off against Azuma Unit and Kageura Unit in the day division of rank battles. Azuma Unit wins the battle, which took place in Exhibition Hall, with a final score of 4-3-3.
