After Destroying the Family, I Cut Through the Abyss with Sparks of Fire

As the young son of an aristocrat in the world of swords and magic, Ryan only wanted to fulfill his previous wish and become a painter. Until the night when the family was exterminated, his parents sent him and his sister down the secret tunnel in tears. During the pursuit, he held his sister and jumped off the cliff. What awakened from the fall was not power, but an ancient star spirit with broken memories that shared life and pain with him. In order to survive, he had to learn to use the hand that once held the pen to control the spark that burned everything. However, the pursuers discovered that beside the "remnants" they were chasing, the stars' pupils reflected the burning starry sky; every flame he slashed was engraved with the lost runes of the ancient gods. When the shadow that had shrouded the continent for thousands of years trembled because of him, Ryan discovered that the annihilation of the family involved a conspiracy that could subvert the world. And what is burning in his palms, is it the fire of revenge or... The only light of hope that can rekindle the era?
