Seiryuu--soon to be called Shin-ah--couldn't have been more surprised when a boy stumbled out of nowhere in the maze-like tunnels of his village; the boy with eyes similar to Ao's, hard and dead, with a glint of cruelty that was probably forced, and, more importantly, a boy that was close to passing out from a fever. Knowing the treatment of outsiders by his people, Seiryuu takes care of the boy himself. The same day the boy, Eren, wakes up, is the day that Yona, the exiled Princess of Kouka, arrives to take Seiryuu away from the darkness to join the other dragons, and Seiryuu refuses to leave Eren at the villagers' mercy. Eren, for the first time outside the walls that protect humanity from the titans, can't help but see the wonders of Kouka as he travels. But he also sees the cruelty and darkness that Yona is just beginning to see, and accepts her request to join their merry group (despite the protests of Hak and Kija) and aid the people of Kouka. "I'm a soldier, after all."
