Yajukon Island

Isla de Reptilia is a mysterious island located off the coast of Japan, it was used as the base of operations of the unstable Dr. Kobayashi Idagawa, who conducted twisted experiments involving animal DNA splicing and human testing.

This lead to the eventual mutation of Akane Hitarashi into the Yajukon who, after killing her creator, continued to roam the island.

The island was reported numerous times as a key location in a string of disappearances, but anyone who ventured to the island never came back.

Details
Yajukon Island is a very foggy area that is mostly comprised of numerous mountains and dead trees, with small abandoned cabins in various places.

There is also a broken bridge that sits above a deep chasm, it is possible that a river flows through below. However the island is mostly used by Dr. Kobayashi Idagawa as a base of operations, as he has a hidden lab underneath the island where he conducts his twisted experiments.

After Akane Hitarashi was mutated into the animalistic Yajukon, she killed Kobayashi and began to roam the island and kill anyone who set foot on the island which lead to higher suspicions on the place. Because of these incidents, Yajukon Island was deemed a restricted area.
