At 12, Izumi Ryuugamine’s village was attacked by the Oreki the Redcorb. Too weak to fight, he watched his clan, including his brother, get wiped out. His brother made him escape to ensure someone would survive to avenge their clan. Years later, after intense training, Izumi encountered and defeated one of his clan’s killers. He vowed to avenge his clan by eliminating the Oreki the Redcorb, killing many of them as he continued his journey.
