Kingdom of Paradise is an action role-playing video game available for the PlayStation Portable handheld system. The game is called in Japan and Key of Heaven in Europe. On April 24, 2008 it was released as a downloadable title from the North American PlayStation Store. A prequel is available in Japan, Korea, and China called Tenchi no Mon 2: Busōden. It was re-released as a PlayStation Network title for PS4 and PS5 in September 20, 2022. Heavily influenced by Asian culture in general, and Chinese Wuxia fantasy in particular, the game contains clans named after the Ssu Ling. The fifth clan is named Kirin and is not part of the group. Story The story of this game takes place in an almost feudal China, which is simulated through the fictitious world of Ouka. The continent of Ouka is separated into five divisions: Northern (Genbu), Eastern (Seiryu), Southern (Suzaku) Western (Byakko) and Central (Kirin). Each of the five divisions has a Clan Lord, clan disciples, a particular style of Chi and sword fighting and a sacred sword. It is later revealed that each sword – except the Kirin Sacred Sword – controls one of the Four Gods of Ouka. There is also reference to the continent of Seima, which is said to be somewhere over the sea to the west of Ouka. Nobody who has ever tried to find Seima has returned. Three hundred years previously there is said to have been the Seima-Ouka war, in which the Clan Lords of Ouka prevailed. However, nobody was alive three hundred years ago to recount the mysterious events of the war – except the Kirin Lord Gikyo and the Seiman twins, Lu Yan and Li Yin (who are over three hundred years old but look deceptively young in the game because they "are able to sustain [them]selves on the chi of the yin and yang moons" as told by Gikyo. Their very names are references to yin and yang – Lu Yan representing the righteous Yang while Li Yin is the mischievous Yin side). The Forbidden Poem, written by Lu Yan and Li Yin, speaks of the war, reading: The main character, Shinbu, has been exiled from his clan, the Seiryu, after looking at the Ancient Monument, which holds the secrets of the Seiryu Chi Arts. The surviving disciple named Sui Lin tracks down Shinbu to tell him that their clan was destroyed,
