Kiyruu Sabato [The Demonic Specialist Doctor]

Guided by Fulst, Kiyruu Sabato is a known sadistic scientist working directly for Nomad. Kiyruu was trained to master the art of hell technology to help aid and benefit the efforts of Edwin Black and the Nomad organization. Yet, despite his close ties to the group, Kiyruu shows no true actual allegiance as he finds himself increasingly bored with the work given to him by Nomad.

Intelligent and deceiving, Kiyruu is never above stabbing people in the back, whether it'd be by betraying them or by actually stabbing them in the back.
