Kingdom of Paradise

Five great gates of Ouka be,
Name them here for all to see;
Sieryu, Byakko and Genbu
Kirin and Suzaku be there too;
At Heaven’s gate twin keys you need;
At Earth’s gates, bows the Divine Steed;
The soul is born as the Yang moon whirls
The body is born as the Yin moon twirls
The twin moons make a mighty hum
From the watery moon, it doth come.

—The Forbidden Poem

An action RPG designed for the Sony PSP, it is known as Tenchi no Mon in Japan and Key of Heaven in Europe. It was released in the US in December 2005 and in Europe in March 2006.

It is heavily influenced by Asian culture as a whole, especially the Chinese Ssu Ling, on which four of the five clans in the game are based.

Despite gorgeous graphics and relatively high ratings by critics, it faced underwhelming sales. It remains a hidden gem in the world of gaming.

Tropes used in Kingdom of Paradise include:

100% Completion: One needs to collect all of the bugei and kenpu scattered about Ouka in order to achieve this.
Adorkable: Eigen.
Badass: Several. Hohaku, Lei Gai, Seidatsu, Soh Yu, Yen Lan, Shinbu; even Sui Lin has her moment.
- Ginritsu in her Crowning Moment of Awesome
Badass Longcoat: Lei Gai.
Berserk Button: Better not tease Yui Min about her size if you don't want a sword in your face...
- Best not to cross her at all, really.
Calling Your Attacks: "Chi Arts - SOARING DRAGON!"
Dark Is Not Evil: As seen with the Ruthless vs. Righteous clans. It is pointed out in-game that the Ruthless clans, Genbu and Byakko, are not explicitly evil; rather, they simply use a different style of bugei and chi arts.
- It's hinted that the Righteous and Ruthless clans represent the yang and yin forces, with the latter being the more 'destructive' force. Hence the Ruthless' powers of Chi Disruption.
I Want My Beloved to Be Happy: The game adores this trope. Yen Lan to Hohaku is the most prominent example, but also applies for Sui Lin (to Shinbu), Xiuk Yu (to Lei Gai), and arguably Soh Yu to Jok Xiu.
Level Grinding: Needed to upgrade Chi Arts to their maximum power.
Level Up Fill Up
Lost Tribe: Uzo and Muzo, the last of the Mt. Gokuho faction.
Palette Swap: For the generic field battles, the 'disciples' are identical save for their uniform color.
