Yutaka Kashio/Plot

Background
Kashio was raised to speak to his parents with the utmost politeness. A natural prodigy, he never experienced failure before joining Border and suffering a crushing defeat at Ai Kitora's hands. At some point he joined Ōji Unit.

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

Large-Scale Invasion Arc
Ōji Unit was seemingly not deployed during the Second Large-Scale Invasion, and could therefore be among the B-rank units with missing members which Masafumi Shinoda prevented 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.

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

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, after Okudera's distraction allows Azuma to snipe Kageura.
