Yona of the Dawn S01 E14 Light

The blue dragon warrior retrieves his mask and begins digging a path out of the cave. The others join him and Hak starts digging from the outside. Hak finally breaks through and reunites with Yona. Yona again asks the blue dragon warrior to travel with them and he accepts. They set off, but Ki-Ja collapses from exhaustion so they stop to make camp. Yona gives the name "Shin-Ah", which she says means moonlight, to the blue dragon warrior. When they awake the next morning, Ki-Ja tells Yona he can sense the green dragon warrior.
