エイリアンヘッドバット

Ouga Shirokiba left Mukurojima, an island of five thousand people, to chase pro wrestling in Tokyo, and he comes home years later wearing the world heavyweight belt. The homecoming lasts about as long as it takes him to notice that aliens have taken the island over. With no help coming, Shirokiba goes at them the only way he knows how: strikes, throws, holds and every dirty trick the ring ever taught him.
