Patarillo! is set in a society much like ours in most ways, with one decided twist. The manga on which it is based is one of the much-read works produced for adolescent Japanese girls that features a healthy proportion of gay men and beautiful teenagers aka bishounen (beautiful boys). Most of the action takes place in Marinera, the land of eternal spring, located somewhere in the South Seas. The country is a major producer of diamonds; they provide much of the basis of conflict in the anime series. They come from one of the most prolific mines in the world, owned by the king of Marinera, the vertically challenged but horizontally endowed boy-king Patarillo himself. The International Diamond Syndicate - a huge semi- criminal organization/ secret society dedicated to taking over the world`s entire diamond supply- wants that mine and will stop at nothing to get it. In the early episodes they send off a number of bishounen assassins to do in Patarillo, which necessitates his having a bodyguard, the English MI6 agent, Major Jack (`Bishounen-Killer`) Bancoran. Bancoran`s nickname doesn`t mean he shoots bishounen in cold blood. The soubriquet comes from the fact that no male under the age of 17 can resist his sexual fascination. This, to Bancoran`s eternal disgust, includes Patarillo himself. The action switches often from Marinera to MI6 headquarters in London (London seems to be an easy two hour`s flight from the South Seas) or Bancoran`s palatial condo in the suburbs of same. (MI6, be it noted, looks a lot like Fritz Lang`s Metropolis, while Jack`s `apartment` bears a passing resemblance to Randolph Hearst`s spread.) The action also goes into the past and future and out into space. Patarillo evidently gets around.

Souten Kouro's story is based loosely on the events taking place in Three Kingdoms period of China during the life of the last Chancellor of the Eastern Han Dynasty, Cao Cao (155 – March 15, 220), who also serves as the main character. The Three Kingdoms period has been a popular theme in Japanese manga for decades, but Souten Kouro differs greatly from most of the others on several points. One significant difference is its highly positive portrayal of its main character, Cao Cao, who is traditionally the antagonist in not only Japanese manga, but also most novel versions of the Three Kingdoms period, including the original 14th century version, Romance of the Three Kingdoms by Luo Guanzhong. Another significant difference from others is that the storyline primarily uses the original historical account of the era, Records of Three Kingdoms by Chen Shou, as a reference rather than the aforementioned Romance of the Three Kingdoms novel. By this, the traditional hero of Romance of the Three Kingdoms, Liu Bei, takes on relatively less importance within the story and is portrayed in a less positive light. Yet, several aspects of the story are in fact based on the novel version, including the employment of its original characters such as Diao Chan, as well as anachronistic weapons such as Guan Yu's Green Dragon Crescent Blade and Zhang Fei's Viper Blade. A consistent theme throughout the story is Cao Cao's perpetual desire to break China and its people away from its old systems and ways of thinking and initiate a focus on pragmatism over empty ideals. This often puts him at odds with the prevalent customs and notions of Confucianism and those that support them. (Source: Wikipedia)
