Togashi, Yoshihiro

Fourteen-year-old thug Yuusuke Urameshi spends his days skipping school and causing trouble for the adults in his life. Yuusuke regularly engages in street brawls against rival Kazuma Kuwabara and ridicules his childhood friend Keiko Yukimura. Filled with self-loathing and the burden of an alcoholic mother, Yuusuke sacrifices it all in a split-second decision—he tackles a small child out of the way of an oncoming car, losing his life in the process.

Spirit guide Botan intervenes, allowing Yuusuke to see how the people in his life react to his death; he is moved by the emotional ruin his loss causes his mother, Keiko, and even Kuwabara. Additionally, due to his death's heroic nature, he receives an opportunity to return to life from the Spirit World ruler's son, Koenma.

Koenma hires Yuusuke as a "Spirit Detective" and tasks him with solving a series of increasingly challenging paranormal mysteries. Battling and befriending demons such as the beautiful Kurama and hostile Hiei, Yuusuke further develops and utilizes his skills as a fighter. But as dark forces move in the Underworld, Yuusuke struggles alongside his companions to defend everything he took for granted.

Ushio to Tora centers around the travails and battles of Ushio Aotsuki, who is constantly being stalked and aided by a gigantic, supernatural and sometimes invisible tiger-like monster.

Ushio's family maintains a Shinto temple in Japan, where ~500 years ago, his samurai ancestor battled that same tiger to a standstill, and eventually trapped him against a rock using a blessed spear called the "Beast Spear," which in addition to its intrinsic formidability as a weapon, can also endow its wielder with the martial ability of the ancestor who originally wielded it.

Ushio accidentally unsealed the cave Tora was trapped in. Initially, Ushio refuses to remove the spear pinning Tora down, but Tora's unsealed presence summons various monsters who wish to fight him, and by extension Ushio. Ushio is forced to free Tora, who would like to eat Ushio, but dares not since Ushio keeps the spear close by. The series focuses on their relationship, interspersed with battles against mythological foes, and with Tora's attempts to grapple with modern life.

Kinnikuman (a.k.a. Kinniku Suguru) is a cowardly, clumsy, moronic, gyuudon-devouring excuse for a superhero (or Choujin)... who just happens to be the prince of an alien planet. But despite his pathetic appearance, he is very honorable and can become quite powerful when he needs to be. With his sidekick Meat-kun and fellow Choujin's Terryman and Ramenman there to help him, Suguru quests to become the greatest Choujin on the planet. Whether with a combination of tremendous heart and stamina (The Burning Inner Strength) or the "Power of Friendship," Kinnikuman frequently defeats villians 10 times more powerful than him and often causes his enemies to have a change of heart and join him. Though he seems destined to be an idiot forever, slowly but surely Kinnikuman becomes worthy of the title "Hero."

Note: Between volumes 36 and 37 publication there's 22 years gap. From volume 38 onwards starts restarted in 2011 version.

Private exorcists for hire; they serve only the highest bidder to survive in the cutthroat corporate world. Among this, the Mikami GS Company, led by Reiko Mikami and her two assistants, the teenage boy Tadao Yokoshima and the ghost girl Okinu, is said to be the best.

Humanity, once a technologically advanced and thriving civilization, has been pushed to the brink of extinction following a cataclysmic war known as the Seven Days of Fire. The remnants of the human race now live in scattered kingdoms to avoid the unrelenting spread of the Sea of Corruption, a colossal forest infested with dangerous mutant insects and fungi that produce poisonous spores.

Nausicaä, the sole heir to the throne of the agricultural kingdom Valley of the Wind, is thrust into war after an ally kingdom, the imperialist Torumekia, invades the Dorok Empire. Forced to fight alongside the Torumekian military and their cunning princess Kushana, Nausicaä witnesses firsthand the horrors of war and its effect on both humanity and the environment. With her uncanny charisma and gentle nature, Nausicaä may be the only hope for humanity as the ongoing war and the Sea of Corruption hasten the extinction of mankind.

Set against the backdrop of a devastated world, Kaze no Tani no Nausicaä depicts the aftermath of human folly and the immortal power of nature.

2019: Fast forward 31 years. Neo-Tokyo, hastily built on the ruins of old Tokyo, is a sprawling cityscape of neon extravaganza. It is a fusion of towering skyscrapers and cutting-edge technology that is permeated through and through with an explosive, hyper-violent cocktail of biker gangs, poverty, and revolutionaries. In this derelict metropolis live Tetsuo Shima and Shoutarou Kaneda, two bikers who are the best of friends and the fiercest of rivals, despite being affiliated with the same gang. Desperate to prove himself as Kaneda's equal, Tetsuo unwittingly pulls a stunt that culminates in the awakening of a cryptic existence that threatens to change both the face of Neo-Tokyo and the lives of those who call the city their home—the awakening of a government secret simply known as Akira.
