The focus of "The Tiger's Hole" is on a clandestine wrestling group, where two resolute wrestlers take the lead. One of them acquires Naoto Itou's tiger mask and his practice center near Mount Fuji. The other wrestler earns the highly coveted black Tiger Mask by competing fiercely. Although they have opposing objectives, one strives for integrity while the other for malevolence, the two have not crossed paths yet. In the end, their common aspiration to vanquish The Tiger's Hole leads them to confront each other as bitter foes in the ring.
