Taking a span of 80 years to reach a D-class. Still, Zlatan Elmore became the most powerful hunter to exist.Falling on the battlefield against a Two-horned Dragon, he suddenly awoke as his 30 year old self. Given another chance at life, he didn't only have his memories but he's also given a Blank Scroll. This mysterious scroll doesn't only speak, its omniscient!
