Jujutsu Kaisen:Cursed Kamuy

In Hokkaido, a hidden world of curses and sorcerers exists. The lore begins centuries ago when two ancient curses, known as Izanagi and Izanami, emerged from the depths of the land. These curses, born from the region's accumulated negative energy, threatened to consume the entire island. In response, a group of powerful sorcerers known as the "Ainu Jujutsu Society" was formed to combat the curse and protect the innocent. Led by their leader, the sorcerers dedicated themselves to studying the curse's origins, developing unique jujutsu techniques specific to Hokkaido. These techniques incorporated the negative emotions of the indigenous Ainu people, granting the sorcerers unparalleled abilities. In the midst of this ongoing battle, the Cursed Kamuy emerged, a group of sibling cursed spirits embodying the essence of ancient mythological figures. These powerful entities, led by Amaterasu, sought to instill fear and reverence in humans once more, regaining their rightful place in the collective consciousness. Over the centuries, the Ainu Jujutsu Society established a network of hidden bases and training grounds across the island, training new generations of sorcerers to combat the curse. These sorcerers, known as "Ainu Jujutsu Students," undergo rigorous training to master their jujutsu techniques and develop their unique abilities. As curses continue to grow in strength and complexity, the negative emotions of humans spawn a variety of creatures and curses, each with unique abilities and weaknesses. These curses roam the wilderness of Hokkaido, terrorizing the inhabitants and feeding on their negative emotions. The Ainu Jujutsu Students, armed with their jujutsu techniques and guided by society's teachings, stand as the last defense against these curses.
