Darker than BLACK -黒の契約者 外伝
Fleeing from the consequences of his decision at the Hell's Gate, superpowered Contractor Hei and his companion Yin take refuge in a quiet inn, adopting the guise of a married couple in order to not draw suspicion. In an attempt to recover from recent events, Hei befriends the inn's other guests. He discovers that one of them is a fellow Contractor tasked with killing him. Their resulting encounter spells disaster for both Hei and Yin, who are forced to fight for their lives and grapple with the...
Hei and Yin hide as a married couple, but a deadly Contractor shatters their quiet refuge.
After the cataclysmic fallout at Hell's Gate, Hei and his enigmatic companion Yin vanish into the countryside, assuming the roles of a quiet married couple to stay under the radar. They settle in a modest inn, where Hei, still haunted by the bloodshed, tries to stitch together a semblance of normalcy by mingling with the other guests. The tranquil façade begins to crack when a new arrival—a stoic Contractor with a hidden agenda—recognizes Hei and sets his sights on eliminating the infamous Black Reaper. The ensuing confrontation erupts into a brutal ballet of electricity and shadow, forcing Hei and Yin to defend their fragile sanctuary. As the battle rages, old wounds resurface, and the pair must confront not only the lethal threat but also the lingering trauma of their past lives. The OVA blends high‑octane action with a somber meditation on identity, loyalty, and the cost of wielding otherworldly power.
