Earth is a planet featured in CROSS ANGE Rondo of Angel and Dragon. The ancestors of all human species came from the original Earth.
Earth was ravaged by pollution and devasting conflicts. After World War VII (aka Ragnarok), some left for another Earth, the humans who stayed behind evolved and are able to turn into beings known as DRAGONs. (CROSS ANGE: "Ange and Tusk", "The Other Earth")
The DRAGON clans reside in an area beneath Mount Fuji.
Salamandinay restored a sports resort more than five centuries old. It has a bowling alley, a tennis court, a baseball stadium, a race track, a golf course, table tennis tables, and rooms with twister and a claw crane game.
Hotel Mu La Flaga
A love hotel that Ange , Tusk and Vivian stayed in temporarily. It was able to withstand the impossible test of time, although some of the furniture such as the couch in Ange's room were very fragile.
These were civilian shelters used during World War VII.
