Eiki, Eiki

Oozeki Arata is a first year high school student who has to find new living arrangements after his parents move overseas.  Arata moves into Zassoukan, which contains four other residents.  The other residents look at this newcomer suspiciously and appear to be hiding something.  Arata soon discovers that they are all mangaka hiding their identities for various reasons.

There's Hayashi Erika, an elementary school teacher who draws shota manga and shamelessly declares that she loves cute, small boys.  Sakura Kanako is a 10 year old girl that draws graphic H manga and is enchanted by large breasted women, including Erika.  Odaka Hitoha, Arata's classmate, draws "nonfiction" BL manga, which means all of his material comes from personal experiences with different men he chases down, which apparently includes the final resident.  Irisuna Fuzuki is a seemingly normal man in his late twenties that works as a shoujo magazine editor, except he also draws a popular shoujo manga for the competition.

Since Arata knows everyone's secret, they decide to make him an assistant.  Will Arata be okay?

Out of the dirty alleyways, one man emerges to shake loose the global foundations of the vast criminal underworld. This man possesses such unearthly beauty that they say whenever he enters a room; the women would become just a little bit looser. Even the men would become a little bit naughtier. But unknown to all, he carries inside of himself a personal vendetta. From Hong Kong, to New York City and to Shanghai, he seduces the rich and corrupt into destroying themselves, by turning their own unholy appetites against them. His name... Shinobu Shikata.

銀晶水

Takemiya, Keiko

Serge Battour is the son of a French viscount and a Romani prostitute, and despite his kind nature and academic talent, is shunned by his family and his peers due to the color of his skin. He begins to attend Lacombrade Academy, his father's alma mater, in the hopes that there he will find a place to belong.
 
Gilbert Cocteau is, like Serge, the orphaned son of a wealthy family, and is infamous at Lacombrade for his beautiful and delicate appearance, lack of dedication to schoolwork, and habit of prostituting himself to other students. He has no intention to connect with any of his classmates, instead devoting himself to his uncle Auguste.

Due to a shortage of living space, Serge and Gilbert become roommates even though Gilbert's antisocial nature has in the past made it impossible for him to room with anybody. Serge, being sociable and idealistic, is determined to be friends with Gilbert; Gilbert is only interested in either being able to manipulate Serge or push him away entirely. To the surprise of both of the boys, however, the two eventually form a deep, albeit generally dismal, bond that leads to a romantic connection.

間の楔

The Poe Clan: a race of undead that feeds on the energy of the living, whiling away the centuries in a village of roses where time and geography have no meaning. Circumstances lead to a brother and sister, Edgar and Marybelle, being initiated into the clan too young, and therefore doomed to live out eternity forever on the brink of adulthood, until a wooden stake or a silver bullet should cut them down. In this groundbreaking manga, through three immortal adolescents and the mortals whose lives they touch, Moto Hagio explores what it means to live and to die, to have loved and to have lost.

Poe no Ichizoku

The Poe Clan

ポーの一族

Maya, Mineo

Once, there was an island where it was always spring...

...An island somewhere in the South Seas, with green forests and wide lakes. And mountains, let us not forget the mountains. Tall mountains with deep roots, filled with one of mankind's most precious treasures: diamonds. The name of this island is Malynera, and its king is only a child.

Patalliro the 8th, King of Malynera, is ten-years-old. From the day he was born, everyone knew he was... unusual. He is a hyper boy, with flashes of genius, moments of thoughtless cruelty, and the ability to make a bad pun out of anything. Smart, but only a child and so he often does very stupid things.

Patalliro! is his story.

He lives in a world very similar to our own, but where the bizarre is commonplace. He manages to get into all kinds of trouble, from international terrorists, to space aliens, to accidental time-travel. His first challenge as king is to stay alive, when a group called the International Diamond Syndicate decides that they want control of the Malynera diamond mines. This is how he meets Bancoran, who was assigned to be his bodyguard during a trip to Britain. It's also how they meet Maraich, who was one of the assassins sent by the IDS.

Patalliro is almost always accompanied by his army of Tamanegi ("Onions," so-called because of their onion-shapped wigs). The Tamanegi all wear identical masks, wigs, and glasses, and are known only by numbers. They are Patalliro's protectors, but protect the world from him just as much as they protect him from the world.
