Chiten no Mon

Tenchi no Mon (Kingdom of Paradise / Key of Heaven) is a single-player action RPG on PSP. You play as Shinbu, an exiled martial artist from the Seiryu clan, who joins forces with Sui Lin to recover stolen sacred swords and stop the Kirin clan from dominating the five Ouka continents through ancient rituals and chi arts. The signature system is Bugei scrolls where you insert Kenpu tiles to create unlimited martial arts combos; you can also charge chi for devastating magic attacks and level up attributes. Combat is fluid with element-matching weaknesses. The story mixes wuxia action, clan politics, and mystery in a feudal-inspired world. It stands out for its deep combo-building freedom, elemental chi system, and atmospheric presentation on the PSP.
