Usayama gives her an outfit (a sexy swimsuit) that will allow her to fight the aliens, but which also sends her constant arousal through the roof.

Will Izumi be able to save the Earth? [tethysdust]

Mihama Academy - on the surface, a closed learning environment established to nurture students who find themselves at odds with the world around them; in actuality, an orchard-cum-prison built to preserve fruit that has fallen too far from its tree. Whatever the circumstances behind its establishment, Mihama Academy is at present home to five female students, all with their own reasons for "enrollment." For better or worse, each girl has established a routine obliging of her current situation; life moves at an idle, yet accommodating pace within the walls of Mihama. Yet with the arrival of the institute's first male student, the nearly preposterously opaque Kazami Yuuji, the students at Mihama begin to fall out of step with their predetermined rhythms. Will Yuuji prove to be the element the girls around him needed to take hold of their lives once more, or will the weight of their pasts prove too steep a wall to overcome? And in the first place, just who is Kazami Yuuji? While the true nature of the "job" he is wont to alight to at the most haphazard of moments remains shrouded in secrecy, one thing is for certain - his encroachment upon the quiet orchard known as Mihama Academy will prove itself momentous in one way or another. And of course, one cannot discount the possibility that perhaps Yuuji himself carries the weightiest past of any of the students...

Short stories about two white cats who have no respect and are just plain cruel. Dark humor warning.

Mad Bull 34 is about the toughest cop in New York City's 34th precinct, Mad Bull (a.k.a. John Estes or "Sleepy"). The story follows his often-violent exploits when dealing the city's criminals with his partner Daizaburo Edi-Ban and fellow police officer Perrine Valley. Plot: Daizaburo Edi-Ban, a Japanese-American, joins New York City's toughest precinct, the 34th. On his first day he is partnered up with John Estes, called Sleepy by his friends and Mad Bull by his enemies, a cop who stops crime with his own violent brand of justice. Mad Bull makes no qualms about executing common thieves with shotgun blasts if they even pose a minor threat to him or anyone around them. Mad Bull also often steals from prostitutes and does incredible amounts of property damage while fighting crime. Mad Bull's unpoliceman-like behavior often puts him in hot water with his partner Daizaburo and the 34th precinct. However, despite how reckless or illegal these acts are, a good cause is always revealed (For example, Sleepy uses the money he steals from the prostitutes to fund a venereal disease clinic and a home for battered and raped women). Perrine Valley, a police lieutenant, joins Daizaburo and Sleepy later on to help them tackle more difficult cases involving the mafia and drug-running. Mad Bull 34 is inspired by the high-action buddy cop films of the 70's and 80's.

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. In 1979, this series was awarded the prestigious Shogakukan Manga Award for shounen/shoujo manga. For those who don't like yaoi - this manga is more of shounen-ai and the sex scenes are nothing like the ones you can see in modern yaoi mangas. A bit of warning: "Kaze..." includes scenes of rape and child abuse (but no shota).

Summary translated from the back cover: The stage is set in the prestigious Private Joshi (girls) Oka High School — or more commonly known as Joshi High. It became co-educational a few years ago, but females still heavily outnumber the males. The number of males could be easily counted. While one would think males would be pampered in such a harem school, the reality is far from being heavenly. It is the world of female domination. [Taken from Baka-Updates Manga]
