This is what Toriyama looked like when he was still hungry to prove he could do anything. The first half drags like a morning meeting, but once it breaks into action the comedy timing snaps into place and the adventure stops apologizing for itself. A 47-minute reminder that fun doesn't need to be precious or self-aware.
Two martial artists, Kosuke and Rikimaru, find themselves stranded on Konpeito Island after a catastrophic accident leaves their ship in ruins. The island itself proves far from uninhabited. A military regime controls the territory with an iron fist, deploying advanced mechanical weapons and ruthless soldiers to maintain order. Beneath the surface lies something far more sinister: a dragon of legendary power, bound to the island's depths and guarded by those who would weaponize it. Forced to navigate treacherous terrain and dodge relentless enemies, Kosuke and Rikimaru must decide whether to escape or confront the forces keeping the creature imprisoned. The island's secrets unravel through combat and discovery. Each battle pushes them closer to understanding what truly lies at stake, not just for themselves but for everyone trapped under the regime's control. Their fists become their only tools for survival as the mystery of the dragon deepens and the danger escalates beyond anything they anticipated.
