Stormguard

First seen in the Tomb Raider (2013) video game, the Stormguard (also known as oni) are an organization of samurai who are sworn to serve and protect the Sun Queen of Yamatai, even after her body being trapped in a decaying body. Legend has it, the Sun Queen was able to conquer the lands of Japan thanks to her Stormguard, who were unopposable in combat. Using the sun queens power over the sun and rain, she would raise up a mighty storms and so the stormguard would ride upon the winds to destroy. Before the ceremony, they were planning to cross the ocean to touch all lands.

Clad in medieval samurai armor, these humanoids seem to be hostile to every outsider, including the mysterious man known as Mathias.
