Meet the yellow dragon, a solid 166 cm of muscle and magic. He rolls into the crew right after the Awa arc, and it turns out he’s been secretly keeping an eye on Yona since she fled Hiryuu castle, sizing up her potential to wield the dragon power. After witnessing her journey, he decided to tag along, appearing at their campfire like a big surprise. Revealed to be immortal, he’s the original dragon warrior with unique healing abilities—his body regenerates from injuries, sprouting tough scales like armor. Oh, and he has a past too, once married to a girl named Kaya who was unwell.
