Profile
Child Prodigy

Tsukasa Okino is a high-school student that is well-known for his high IQ and ability to skillfully fumble people. Okino is also the one responsible for various technologies including some Sentinel generations and armaments. During the 2064 Battle, Okino was fighting with Juro Izumi, Ei Sekigahara, and Ryoko Shinonome in the Sentinels, but after the infection incident, he was transferred to 1944 and went into hiding. Fortunately, Okino's short, silver hair, petite build, and high-pitched voice allowed him to pass as a woman by the name of Kiriko Douji. In 1985, with the help of his newfound friend Takatoshi Hijiyama, he seeks to prevent the destruction of the world by any means necessary.
