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.

Fujita, Kazuhiro

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.

Due to problems caused by the homeless spirits, a new profession was created, the Ghost Sweeper (GS). 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.
