Ajin Part 2 OVA

Long before Satou becomes one of the most feared Ajin, he serves in a military operation in Africa involving the capture of the first known immortal human. The mission exposes him firsthand to the terrifying implications of Ajin regeneration and to the ruthlessness surrounding their discovery.

When Satou himself suffers a fatal injury and comes back to life, the truth changes everything he understands about his own body. What should have been another operation becomes the moment he realizes that he belongs to the very phenomenon he was sent to capture.
