History:
Oboro is one of the primary antagonists in the Taimanin Asagi visual novel series.
She is a criminal psychopath, lacking empathy and gets sadistic joy humiliating others. She gains extreme satisfaction and pleasure for causing other people humiliation and pain, making her act like a sadistic dominatrix.
She is arrogant, vindictive and gets unhinged violent if things don't go her way. Furthermore, she seeks power but does so underhanded, not to become a clear target.
She is the arch enemy of Asagi, leader of the ONT, subordinates to Edwin Black, executive of Nomad and master of the first Chaos Arena. "Oboro" is the revived body of the Taimanin, Koukawa Oboro that had been demonized and is missing the original soul. After TA1, she has been revived once more, as a vampire, but later in TA3 during the canon timeline she dies again.
But since TA3 does not take place in the non canon TABA timeline, Oboro is still alive and kicking as vampire and still a member of Nomad.
