Kyoichiro
Kyoichiro was a modern human who got pulled into the Tsukasa Empire's world when he was depetrified in 5739. He ended up serving as a soldier for them.
You'd recognize him pretty easily by the distinctive petrification mark running horizontally across his face—it cuts right through his eyes and over his nose, giving him this look that's kind of like he's wearing an invisible pair of glasses. His ash-blond hair was kept in a small ponytail.
