A story about a prostitute named Lei Shi. A girl from Earth goes to a concave and convex world, looks for a way to get home, and accidentally encounters an interstellar pirate, causing thunder and fire. It may involve popular characters (Gadroth, Anmishu, Kamikoyo, Gray, etc.), So don't enter if you don't like it. They are so handsome that I can't help but have sex. I highly recommend watching The World of Convex and Convex. Also, there are some settings that I did not follow from the original work, so please forgive me.
