Hero

It's been several years since we first saw the first hero. It wasn't long before they discovered others. Although we were afraid of them at first, we began to rely on them over time. They actually became such guards for us who protected us. But what a panic broke out when they all disappeared out of nowhere... One young man managed to save the objects that remained after them, and tried to figure out what had happened to them. He was on the trail of a mysterious artifact that would help save the hero, but he disappeared out of nowhere... Will you succeed?
