From Viz:
It is the middle of the 21st century and Tokyo is expanding more and more, filling Tokyo Bay with landfill to make room for the bursting population. But suddenly Tokyo suffers one of its greatest earthquakes, and the landfill liquefies, creating untold damage in the newly-made urban area. The members of Self-Defense Force Rescue Squad Four are sent to help. But what they dig up is a plot of murder and destruction--one that wipes out nearly the entire squad and leaves its two surviving members, the fierce Rei and her cool, handsome partner Uozumi, in a fight for their lives.

There is only one place where they can find the work that keeps them alive, and the support so they can start uncovering the mystery that killed their squad: that's in the south-Shinjuku bar called Chicago. As the earthquake levels Japan's largest city and capital and leaves countless dead, rescue workers, Rei and Uozumi, search for survivors amidst the rubble of Bay District D only to find a mysterious string of dead bodies--bodies with bullet holes. Without warning, the pair is under fire from the air as a hail of gunfire rains down. Are these the killers, and if so, what is their purpose? Barely escaping with their lives, Rei and Uozumi discover that their squad is listed only as "collateral damage" and their records wiped clean.

From Wikipedia:

An innocent young man, Ikuroo, has a parasite known as Baoh implanted in his brain by an evil organization, Doress. The parasite makes him nearly immortal and gives him the ability to transform into a really powerful beastie when he's in trouble.

Doress intends to use him in some sort of ploy for world domination. But while they're moving him around, a young psychic girl, Sumire (who's also being held by the organization), sets him free, and the two escape together. Of course, Dr. Kasuminome is the mad scientist behind the whole thing, and he isn't about to let his test subject get away... and he has everything from superpowered lackeys to a small army at his disposal.

Hundreds of millions of years ago, highly-advanced beings looking to make a planet for themselves purposefully tampered with Earth's natural processes in order to create multi-cellular life. Watching the planet's evolution closely, they continued to help life evolve further in the hopes of having actual civilization develop.
It's now 1996 in Seoul, where Hyesong, a high-school student, struggles with the usual problems of youth. The only unusual thing about him is that he's been having the same apocalyptic nightmare for an entire month; in the dream he is an great fighter and genius tactician who faces off against a seemingly-unbeatable foe.
Are these dreams not really dreams? Does he really have a role to play in the cosmic balance of the universe? And is the new girl in his class really just a normal student?

From back of book:

He-Sung has dreams of the Earth being destroyed by alien invaders! In these dreams he is a motorcycle-riding warrior, the last defense against the alien armada. By his side is a beautiful armor-clad girl with strange powers and futuristic weaponry. But these are just dreams, and they don't mean anything... right? That's what He-Sung thought... until his mystery dream girl appeared as a new student in his school! But if she is real... can the aliens be far behind?

From Ryuusei no Mafia:

Minnie’s the only human living on an alien planet and because of that she’s rejected by almost all the other inhabitants. Then one day something falls outside of her house and it happens to be... a human prince?!

The protagonist is your average, everyday, Korean school student. That is, if not for his obsession that aliens live on Earth disguised as humans.

Much to his surprise, he was right, the aliens play a game called "Avatar" where they take human form and live human lives. And because of a glitch he caused in their system, now his very life could be at risk.

Now he needs the protection of an Admin of the "Avatar game" or else he could very well die!

From Tokyopop:

Daphne in the Brilliant Blue take place in a near future in which the remaining population lives in underwater cities, with waterways as streets. Years ago, while conducting underwater experiments, all contact with the surface was cut off. With the remaining human population now living underwater, The Deep Sea 9 Cities Association represent the last hope of mankind. Ai Mayuzumi is the daughter of the head of the research lab, and is an expert water jet bike driver. When the terrorist group Error, attacks the city, Ai becomes involved with the counter-terrorist group Stelnas, comprised of an all-female team, and led by a girl named Kei, and asks to join them. The group initially resists her efforts to join, but a surprising "gift" that Ai possesses, along with the way she handles herself during a kidnapping attempt, eventually sways the opinion of the members of Stelnas.

This is an original story expanded from the STEINS;GATE game, and focusing on the heroine Amane Suzuha. In 2036, a monopoly on time machines has created world peace, but at the cost of human liberty.

Suzuha has followed in her late father's footsteps in fighting alongside the Valkyrie rebellion force to change the world. After the group fails on a major mission, Suzuha has almost no hope left. But then she discovers that her father left something for her: a time machine. Using this, maybe Suzuha will have the power to finally destroy this dystopian society and create a better present and future!

Bard is a tough guy involved in a shady business; Sei is a tough kid engaging in some shady dealings. Through sheer stubbornness (and the fact that Sei-kun made a very, very bad hooker), Sei ends up working for Bard, and there's instant attraction.
