Reiri Hida

Hida Reiri (飛弾 怜悧) is the principal and commander of Ataraxia. She becomes the leader of Ataraxia after it became an independent country. She is the daughter of Hida Nayuta, as well as the older sister and semi-secret lover of Hida Kizuna and adopted older sister Hida Setsuna. Carrying the heavy responsibility of protecting her world from the threats brought by the AU Conflict , Reiri was the one who started the Heart Hybrid program by having all of their Heart Hybrid Gear pilots do Climax Hybrid with her younger brother Kizuna, which meant doing lewd and sexual acts with him. Despite the questionable morals and strangeness of her methods, Reiri's decisions have always been for the best and greatly contributed to many of Ataraxias' victories throughout the series.
