Oboro

Oboro was a once a skilled member of the Taimanin Force but eventually betrayed them and even killed many members. After her betrayal, Oboro would join forces with Edwin Black and even be in charge of the Chaos Arena, a place where Blacks subordinates watch both regular people and Taimanin for their own twisted amusements. Due to constantly encountering Asagi Iwaga, Oboro would become Asagi arch enemy.
