Haya Kittaka/Plot

Background
Kittaka opted for a design track in high school befriending Fujimaru (a fellow schoolmate) during her enrollment. 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 Squad. 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 Squad presumably takes part in the extermination of all Rads in Mikado City.

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

Round One
Ōji Squad starts the season off at 5th place meaning they fought in the upper group but what what squads they fought, the division or what their rank was afterwards wasn't shown or said.

Round Two
During the four-way rank war of the day division on February 5, Ōji Squad faces off against Azuma Squad, Katori Squad and Yuba Squad. The three Squads manage to force Haruaki Azuma to Bail Out by focusing their fire on him and was able to do good enough to still be in 5th place after Tamakoma second's match.

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

Round Four
Since Tamakoma Second fights Ninomiya Squad, Kageura Squad and Azuma Squad in the night division of rank wars on February 15, and since Katori Squad and all other possible opponents were in the middle tier of B-rank or lower, Ōji Squad must have fought in the day division against Ikoma Squad and Yuba Squad. After the scores from both divisions are tallied, Ōji Squad remains in fifth place with 22 points.

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

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

Round Six
On Saturday February 22, Ōji Squad fights Tamakoma Second and Ikoma Squad in the day division of rank wars. 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 Squad scoring a total of three points.

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

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