From Tokyopop:

Zerodaimu Kyupura Pa Azalraku Vairu Rua Darogu (a.k.a. Zero) once stopped the evil demon lord with his incredible psychic ability, and in the process saved the world from destruction and earned the honorable and highly imaginative title 'The Man Who Stopped the Evil Lord.'

Among the student body is young Ai Shiomi, Zero's little brother, a somewhat meek boy who, despite parental prodding and his fraternal reputation, feels that his limited skills hardly justify his presence at the prestigious academy.

However, everyone else is convinced that he, like his celebrated brother, is destined for greatness. A lot of pressure for a boy just entering adolescence!

The story detailing the past of Senomiya Misaki, elder sister to the Robotics;Notes heroine Senomiya Akiho.

Michio Yuki has it all: looks, intelligence, a pedigree as the scion of a famous Kabuki family, a promising career at a major bank, legions of female admirers. But underneath the sheen of perfection lurks a secret with the power to shake the world to its foundations.

During a boyhood excursion to one of the southern archipelagos near Okinawa, Yuki barely survived exposure to a poison gas stored at a foreign military facility. The leakage annihilated all of the island’s inhabitants but was promptly covered up by the authorities, leaving Yuki as an unacknowledged witness—one whose sense of right and wrong, however, the potent nerve agent managed to obliterate.

Now, fifteen years later, Yuki is a social climber of Balzacian proportions, infiltrating the worlds of finance and politics by day while brutally murdering children and women by night—perversely using his Kabuki-honed skills as a female impersonator to pass himself off as the women he’s killed. His drive, however, will not be satiated with a promotion here and a rape there. Michio Yuki has a far more ominous objective: obtaining MW, the ultimate weapon that spared his life but robbed him of all conscience.

There are only two men with any hope of stopping him: one, a brilliant public prosecutor who struggles to build a case against the psychopath; the other, a tormented Catholic priest, Iwao Garai, who shares Yuki’ls past—and frequently his bed.

Akikaze Cosmos is a regular elementary student who also helps take care of the hostel that her mom operates in the town of Hanami. She is incredibly responsible for her age and seems much more mature than the other older residents of the hostel, like the high-school girl Soyokaze, the college drunk Sonoko, and the pervert Raita. Everything about this hostel and the town of Hanami seems normal except that everything outside of the town is a nuclear desert where no one is allowed to enter.

Kuuki no Soko is a collection of short stories drawn by the genius mangaka, Tezuka Osamu, between 1968 and 1970, and is known in Japan as a true masterpiece.

Belonging to Tezuka's most mature period, it touches many genres: from pure science fiction to historical fiction to contemporary drama. We find stories of industrial espionage, animal testing, and racial animosity, as well as stories about the more complex dynamics of the human mind.

And the human mind is the leitmotif of the entire volume, namely the duality present in every one of us - mercy, love, and understanding, existing together with cruelty and violence until something upsets the balance and we discover a side hidden even from ourselves... a side we are not always prepared to confront...
