Unordinary Mage

On a dark cold night when most people were asleep under their warm duvets, a young blonde-haired boy was laying on the ground as he gave the demon in front of him a cold stare. "Leave my sister alone!" he shouted. "If you give me 1,000,000,000 gold coins, I might consider it." the mysterious being replied before leaving through a portal. Thus, to save his sister, Soma Yasushi started his journey of becoming a mage with a thirst for money that could drain everything from even the richest country. Along his journey, he would find out more about his own identity, the mysterious being, and make friends that would help him along his path.
