So picture this: One day, Jae-ha suddenly senses that the next green dragon has been born. He thinks "Oh god, I don't want that poor kid to go through what I did." He tells this to the other dragons. Kija, predictably, says "Well then! We can't let our new little brother be treated like you were! We must take him to be raised at the Village of Hakuryuu immediately!" However, they don't want Yona or Yoon to worry, so Jae-ha decides to make a trip to the Village of Ryokuryuu on his own. He sneaks that kid out of the village before they can chain him up, and takes him to be raised by Grandma at the Village of Hakuryuu. "To think that I would have the honor of not only raising multiple generations of Hakuryuu, but the Ryokuryuu as well!" she exclaims, and promptly raises the kid just like with Kija. The boy grows up calling Yona 'Nee-chan', Hak 'Aniki,' Yoon 'Onee-chan,' (a habit which he never fully gets over and which irritates Yoon to no end, but he can't bear to correct because the kid is just that cute) Shin-Ah 'Nii-chan,' (which he is quietly touched by) Zeno 'Jiji,' (old man, because how else is he going to tease Zeno about his age?) and Jae-Ha 'Oji-chan,' (uncle, which just makes him that much more self-conscious about his age).
