This is a no-holds-barred story about an ex-biker gang leader turned cop, Kenji Date. Operating under the nickname Hyena, Date rubs pretty much everybody within the police force the wrong way as he goes about his business ridding the city of all its scum.

Bad Police also contains two separate short stories at the end of the volume:

Bomber

The Chinese leader, Deng Xiaoping, had promised to rid Hong Kong of its criminal organizations. One of the places they migrated to was Japan. Kamon Shou is a delinquent who just got released from Youth Detention after spending two years there and is about to feel first-hand the effect the Hong Kong mob has on Japan.

Artemis

Ginko is a detective working for the famed Holmes Detective Agency, an agency that takes on the most dangerous of jobs: ones that even the police wouldn't even think about doing. She gets hired by Ms. Nancy to retrieve her seven year-old son, Tom. Tom was taken away by her father-in-law's mafia organization in hopes of cultivating Tom to become the next leader.

Kazuki's had a 16 year grace-period of peace and relative normalcy; smuggled to Japan and raised by a kindly old woman he's grown up to be a bright and friendly boy. His childhood friendship to the girl next door is just beginning to blossom into romance and the death of his ward leaves him with enough character-building angst to set him up for just about any cliche shoujo adventure Yukari Ito has in mind. Unfortunately, Yukari Ito is TOTALLY insane and has decided to make him a vampiric kitten engaged from birth to a Nightmare. (from doki-doki)

From Twisted Curiosity:

Meguru is an ordinary schoolgirl on a school trip. They stop to take a break and she is determined to confess her feelings to the boy she likes, Yashiro.

When they get back on the bus, however, a strange man grabs her and says that he's bus-jacking them. He shoots Meguru for putting up a fight and she thinks, fading into oblivion, ?I wish I could go back in time?. The next thing she knows, she has woken up in her bed at home and quickly finds out that it's the day before! What in the world?

Yukikaze is just a young girl but her and her friends have the incredible responsibility of being the naval force of her nation. As part of Seiran Team 3 of the Wadatsumi naval base, Yukikaze and her female friends, Isokaze, Nowaki and Takao, all attend the naval academy. But in this world, they do not work on ships, instead, they themselves are the weapons, able to travel across oceans at high speeds and engage in warfare using their equipped artillery. When an enemy nation attacks the base to take control of an important strategic point, only Yukikaze is left standing and all hope seems lost when a beautiful woman named Taiwa appears with the secret weapon to defend Yukikaze and the naval base.

Like the earlier Battle Royales, a class of middle school students are picked to compete in fights to the death on an island until there is only one left.
The manga follows the point of view of Girl #10 Makoto Hashimoto, an unlucky girl who fears that her class will be chosen to participate in "the program," a mysterious event that forces students to kill each other. Makoto attends Shikanotoride Junior High School. After the encouragement of her best friend Itou Yamamoto and her mother she decides to face the chances. Her fears are supposedly put to rest when word spreads that all 50 Programs had already been executed in the year making them 100% unlikely to participate....

From Tokyopop:
In the future, random Jr. High School classes are chosen to compete in a game called Battle Royale. The rules: only one student can survive after 3 days on an island or else they all perish. Weapons are handed out and each student is sent out into the field alone and unprepared for the horror that awaits them. The classmates turn upon themselves in a battle for survival, treaties are made and broken, and former friends become foes as the relentless countdown continues. Amid the betrayals and rising body count, two classmates confess their love for each other and swear to survive this deadly game together.

Note: An English-language release of the collected volumes, published in the United States, Canada, and United Kingdom by Tokyopop, was extensively rewritten by Keith Giffen, whose script does not completely follow the original manga. This adaptation makes several changes to the plot. Most notably claiming "the program" is a reality TV show and changing the time that the story is set in by almost 10 years, both of which are contradicted in later volumes.

From Vampire Knight:
Ai was your normal, everyday grade teenage girl until one day, she was involved in a fatal car accident. In the hands of the Specialized Secret Police Organization, she was able to be revived. With her newly gained powers acquired through the operation, she becomes a defender of justice. With the mysterious (and a little perverted) bishounen Sagiriya Shinogu as her partner, she fights the forces of evil!

Heartbreaking and cathartic, Bathroom Guuwa Story tells the story of the maturation of four women from their experiences with a quiet, patient and proud man.

1-5) Bath Towel
Bath Towel is a quirky story about Izutsuya Anju, a hedonist, and his taciturn co-conspirator Monono Kejime. Together they operate a honey trap: Anju will seduce their target, and cameraman Kejime will record their compromising affair. With the money they gained from their blackmailing, they get into all sorts of trouble. Too engrossed in living their lives to the "fullest", they also ended up failing their grade; Anju is a third time third year and Kejime is doing his third year a second time.
