Three scientists crack open a problem that's consumed their entire careers, on attempt 2,503, and the show lets you feel the exact weight of that moment before it pivots to pure invention. This is origin-story scaffolding that actually respects the grind, the failure, the specific desperation of people betting everything on one impossible idea. By the time Ninja-Gum exists, you're already bought in because you watched it cost something real to make it.

Three researchers at the WNA Research Laboratory branch in Eagle City, Komerica, stand on the edge of a breakthrough. Burton, Berecca, and Ron have worked relentlessly to develop Ninja-Gum, a mysterious substance meant to awaken dormant ninja DNA in people who descend from the legendary mercenary warriors of old. After 2,502 failed experiments, their 2,503rd try finally succeeds. Ninja-Gum exists. Thrilled, Burton and Berecca lose no time in chewing it themselves, and then something happens. A single ONA episode, this sci-fi origin story with a supernatural streak shows how Ninja-Gum first comes into being.
