Shinsenkyo

Shinsenkyō (Japanese: 神仙郷, lit. Divine Paradise), also known as Kotaku (こたく), is a fictional island and the main setting of the manga series Hell's Paradise: Jigokuraku and its video game adaption Jigokuraku: Paradise Battle. It is located southwest of the Ryukyu Kingdom. The island is inhabited by a group monsters known as Lord Tensen and had been said to possess the legendary Elixir of Life, which had been sought out by humans for centuries. Kotaku is the main setting throughout the series.

Following the events prompted by the Vanguard Party, the Tao of the island would be destroyed and left on the verge of dying. The creation and design of Shinsenkyo is based on Mount Penglai, a mystic land in Chinese mythology.

Shinsenkyo is the Chinese-inspired region in Hell's Paradise: Jigokuraku. It is located southwest of the Ryukyu Kingdom.^[1] The island is known as the location of the elixir of life, in which the death row criminals must retrieve to obtain a pardon for their crimes by the shogunate.^[2] Shinsenkyo reflects many traditional Chinese cultural elements in its customs and traditions. Which is evident from its inspiration by Mount Penglai, and the many interpretations of topics related to the philosophical concept Tao. Multiple monsters are said to inhabit the island.^[3] Kaku created the inhabitants of the island with heavy influences from Chinese Taoist mythology, basing them off the sage group known as the Eight Immortals, who achieved immortality by mastering paradoxes. Eight Immortals.^[4] Kaku adapted them into gender-fluid beings that embody the Yin-yang balance, possess godlike powers, and rule over Shinsenkyo.^[1][5] The name "Shinsenkyo" itself comes from a real sacred garden in Hakone, Japan, created by Mokichi Okada between 1944 and 1953 as a concept of paradise on earth.^[1] In English, "Shinsenkyo" (神仙郷) translates to "Divine Paradise".^[6]

A thousand years ago, Chinese explorer Jofuku had found the island following his quest to retrieve the legendary elixir of life for Emperor Qin Shi Huang.^[7] He declared himself ruler and devoted his life to researching the secrets of immortality by experimenting with Tao, resulting in the creations of multiple abnormal creatures.^[4] People accompanying Jofuku were converted into the Hōko race.^[3]

After Jofuku's death from Arborification, his wife Rien had committed to his revival by the continuations of his research in developing an elixir of life with the help of around several life-forms created with her own Tao.^[7] Together, they became the new rulers of Kotaku known as Lord Tensen.^[3][6] While devoting themselves to the ways of Tao in Hōrai, they guided the Hōko through the Sōshin using fabricated beliefs involving mortality in order to secretly observe their way of life, as well as use them as resources to replenish lost Tao in the midst of training. Mei, a member of Lord Tensen had learned of Rien sacrificing the lives of the Hōko for her research and attempted to stop her.^[3]

After 200 years passed, the Hōko reached the verge of extinction from experiencing Arborification. This encouraged members of Lord Tensen to become concerned about losing their source of nourishment.^[3] This spawned the idea of luring in humans from the mainland to act as the source. The plan was successful as they managed to ambush the first group of humans who came to the island. Using the Waitanhua Flower, they can extract Tao from other life-forms.^[6]
