For thousands of years, massive holes called chasms lead deep into the Earth. Home to a variety of creatures, ruins, temples, and other mysteries, humans have sought out to explore all parts of the Chasm. However, a thousand years ago, monsters called Kegare have come up to the surface, and the only way to defeat them is with the magical weapons found in the Abyss. Karna, a teenage youth, stumbles upon a magical spear called Visavi Shakti, which grants him the power to control fire. Becoming the savior of humanity, Karna sets out to destroy all Kegare and make the world a place where everyone can live in peace.
