Reiki

Reiki, or the Spirit Tortoise Nation, is a country located east of Melromarc which housed the Spirit Tortoise. The country's residents were killed by the Spirit Tortoise's familiars at the beginning of the Spirit Tortoise's attack.

History
After the initial beheading of the Spirit Tortoise, Naofumi and his party climbed on its shell and discovered a nearby town. Upon further inspection, they found that the town was completely ruined with rotting corpses in the streets.

In a temple, Naofumi found a mural of the Spirit Tortoise with illegible Japanese writing from a previous hero named Keichi. This mural gave information on how to kill the tortoise and why it was sealed.

International Relations
According to Risha, Reiki has had isolationist policies for about a hundred years to protect its unique culture.

Landmarks
The architecture within Reiki has been noted to be distinctly Chinese with buildings that include a castle and temples. On the back of the Spirit Tortoise itself is a small town.

Keichi's Inscription
Keichi is a previous hero who had sealed away the Spirit Tortoise. Within one of the temples, he had written an inscription in Japanese for future Heroes to read. Unfortunately, this inscription has degraded so portion of it are illegible. The inscription mentions the following:


 * The Spirit Tortoise is very dangerous and is equivalent in power to the seventh wave.
 * Breaking its seal will release a terrible catastrophe that will kill many lives. However, this sacrifice will save the world by preventing future waves.
 * To defeat the Spirit Tortoise, both it's head and heart must be destroyed.
 * The eight Vassal Weapon wielders will assist the Legendary heroes.

Trivia

 * The Spirit Tortoise seems to be inspired from the Chinese legend of a giant spirit tortoise holding up Mount Penglai.
