The Astonishing Raigyo

"'Akiyuki, you gotta cheer up! Everyone else is happy to see him return! He's a Xam'd and his name is Raigyo. Next episode, The Astonishing Raigyo! Don't look so depressed.' - Akushiba, narrating the preview for the episode"

Summary
Raigyo Tsunomata, the Xam'd that appeared at the bridge, returns to the Zanbani after two years of absence. All members of the crew seem to be happy to meet him again, as he gives them all gifts to their liking. A green soulstone is received from the tunnel and will be used for future Hiruko endosymbiont experiments in the research laboratory. Akiyuki gradually becomes irritated because he feels he is being bossed around by Raigyo and ignored by the others. Haru tries to convince Kagisu that Akiyuki is still a human being as Xam'd. Raigyo discusses with Nakiami that her village plans to retake the Holy Land from the Northern Government.
