Two young wrestlers confront each other in the Tiger's Lair, an underground wrestling organization that has recently been revived and which destroyed the dojo where they were raised. One wrestler has taken over Naoto Date's training facilities at the foot of Mount Fuji, along with the mask Date left behind. The other dared to enter the Tiger's Lair and won a fierce competition, earning a jet-black tiger mask. One tiger follows the path of light, while the other follows the path of shadows. Neither knows the other's face. In the ring, they are natural enemies, yet they share the same goal: to destroy the Tiger's Lair!
