Ryuoh is owned by Princess Ayeka. The ship consists of a saucer section with two decks, a wooden outer hull, and a sentient Juraian Space Tree as the ship's computer.
The interior of the saucer section houses the following:
Though I'm not sure about the location of Sasami's Bedroom, and the Support Areas. Ayeka has been rather reluctant to answer my questions about her ship. And when I asked Ayeka she told Sasami to be quiet.
Yosho's ship is half the size of Ayeka's ship. But that doesn't mean the ship is less powerful than Ryuoh. Inquiring about Yosho's ship earned me nothing more than a good whap on the side of the head by Ayeka. I wonder what her problem is? Anyway I managed to get some usefull information out of Sasami before Ayeka ordered her out of the room.
Yosho's ship has the traditional saucer section to it surrounded by a wooden frame. The saucer contains two decks and a fairly large size sentient Space Tree.
Though not as big as her sister's ship, Sasami's ship is still rather impressive. Sasami's ship is capable of FTL speeds and atmospheric flight. The Juraian Space Tree computer is rather small indicating that the Tree is rather young.
According to the data I received... Sasami was handed ownership of the ship by the Emporer of Jurai on her 7th birthday as a birthday gift. The Space Tree was instructed to protect Princess Sasami to the best of it's ability, and to obey all orders given by Sasami.
Though I'm sorry to say that Sasami's ship was severly disabled in an accident over Japan and is shipwrecked in a deep lake not far from the Masaki household. Though I have yet to pinpoint it's exact location for further study.
