Kinniku Jima

作品概要

Muscle Island. No civilized equipment can be brought here, and the only thing you can rely on is your own well-trained muscles! Shibaki and Narita are dispatched as observers to the island, which is crowded with such macho people. What miracles are woven into the well-trained human body that they see...?
