The soviet interstellar fleet is heading to a new world for humans to settle. Our protagonist has a goal. He is doing his best to become a part of the ruling class on the yet to be colonized planet while his peers are having fun in the Simulated Reality. But something wrong happens on the way there.

42 year old “shachiku” (company slave) Matsuda Takeshi gets worked to death, as is customary in Japan. His one dying wish is to work for a decent enterprise, not the black company he had been working for. His wish is heard by a god who, for his own amusement, has him reincarnate as a young elf male in another world, with increased affinity for earth magic and ability to command golems. The new golem master sets out on a quest to acquire the Seven Treasures left behind by a legendary mage from 1000 years ago.

While Dokgo Rewind is the prequel to Dokgo, the latter series should be read first.

Revenge~Sure is a sweet thing!

One day, Akio Asakura, a third year high school student, is driving his Fairlady Z (Z31) and is challenged by Tatsuya Shima, a doctor, in his black Porsche 964 Turbo (nicknamed the "BlackBird"). With a friend in the passenger seat and two girls in the back, Akio pitifully tries to win, but is defeated. Determined to become faster, he goes to the junkyard to buy parts for his car, when he sees a pristine, unscratched midnight blue Fairlady Z (S30) in the junkyard. Intrigued as to why such a machine is about to be junked, he buys it. He soon finds that the car is unnaturally fast due to a tuned L28 engine, bored and stroked to 3.1 liters combined with twin turbos, which produces 620bhp. He also finds that all of the car's previous owners had unfortunate accidents in it, starting with the first owner's death. The manga follows Akio's various encounters, though the central plot revolves around his constant battle with the BlackBird for superiority.

Note: The story gets its roots from the actual street racing that occurs on Tokyo's Shuto Expressway, one stretch of which is known as the "Wangan", literally meaning "bay side" (although it is generally used to refer to the freeway), the longest, straightest road in the entire country. Of course, there's also lots of traffic to contend with, including a fair number of heavy trucks. Because of this, the action is inherently hazardous, and wrecks are common. Blown engines are also a frequent hazard, especially with the extreme-high power engines.

Won the Kodansha Manga Award for general manga in 1999.

I, an ordinary high school student, Kimizuka Kimihiko, who easily gets involved in things, was appointed to take care of mysterious attache cases by mysterious men in black suits. After meeting a beautiful angel-like detective girl, named Siesta in a hijacked plane, I became her assistant.

And from there–
[You deal with the beehive, and I’ll restrain the enemy.]
[Don’t make plans that make me the victim.]

We had those kinds of foolish conversations, all while being completely broke every day and fought against <The enemies of the world>. Even when there were hurricanes, the weather-beaten duo sleep past it. Sometimes when we saved money at a casino, we would jump around on the beds at a resort hotel, only to be broke again the next day. We would walk through deserts, traverse through jungles, conquer mountains, cross oceans– The great detective and her assistant would go through these dazzling adventures–

Until she died.

And this story starts from 1 year after that incident.
I’m the only one who’s left, but I carry on her remained wishes.
This story is far from over..

Her ability to detect lies has made her an outstanding officer of the law – despite being haunted by her inability to save the ones she loved from a gruesome fate many years ago.

After Kang Hu’s death from bullying, the family was torn into pieces. His younger brother suppresses his resentment and heads back to school. The story begins exactly one year after Kang Hu’s death when his brother seeks to destroy the delinquent circle

Long, long ago, humans lived almost the same as beasts... If you got hungry, you could just find something to kill and eat it. If someone attacked you, kill them too. Everything was kill to survive, kill to survive. Then people started acting smart and making laws. The laws kept them from doing pretty much everything they wanted to do. Beasts, on the other hand, still have no laws, or etiquette. I predict the day will come when an almost mutant breed of humans will appear, sinking to the level of beasts for freedom... Here, I will call them "Vampires..."

Now that Soma seems to literally be a starting character in the game world, will he re-spawn after death, or actually die? Luckily, he knows just about everything there is to know about the world of Neko-Mimi-Neko, so he may be able to make the unfairness in the game work to his advantage.
