Batman: Death Mask

A ruthless new serial killer is terrorizing Gotham’s criminal underworld, leaving behind a trail of deadly masks and unsettling clues that point to an unexpected origin. The murderer appears to possess intimate knowledge of Bruce Wayne’s formative years spent training in Japan—raising the terrifying question of whether this figure knows the Dark Knight’s true identity. To stop the rampage, Bruce is forced to confront his own history and examine how his time abroad shaped him into Batman, wondering if those very experiences inadvertently forged the monster now hunting Gotham. As the mystery unravels, the killer exposes a deep-rooted connection to Bruce, revealing that they were once fellow students studying together in Japan years ago. This dark bond culminates in a final confrontation with a lethal adversary known as the Oni. However, before Batman can defeat this formidable enemy, he must first overcome the lingering shadows of his own troubled past.
