Kyouya Kirigaya

The captain of the 15th test platoon. He is the primary rival of Takeru Kusanagi, as well as being his acquaintance since middle school. He is contracted with Nero.

Kyouya was born into a rough family whose upbringing molded his near-constant aggressive demeanor. This behavior had him grow close to Takeru during their antagonistic middle school days but the latter's pacification strained Kyouya's view of him. Kyouya's belligerent attitude followed him through his academy days where he surprisingly proved himself to be a capable and supportive squad leader where he led his platoon to become the Top 3 ranking platoons in the academy. Ikaruga, who has known him since middle-school, surmises that Kyouya's aggression also stems from his determination to escape mediocrity. He nevertheless went out of his way to taunt Takeru if given the chance and these bouts were usually calmed down by his childhood friend Yoshimizu.
