Yuyu Hakusho

## introduction

YuYu Hakusho (Japanese:, Hepburn: Y Y Hakusho) is a Japanese manga series written and illustrated by Yoshihiro Togashi. Yusuke Urameshi, a young offender who was murdered by an automobile after trying to save a child's life, is also the protagonist of the television show. Yusuke is awakened and given the title of "Underworld Detective," with a responsibility to investigate into numerous crimes involving demons and apparitions in the Human World, undergoing a series of assessments administered to him by Koenma, the son of the ruler of the afterlife Underworld. As the manga progresses, martial arts tournaments and conflicts take center stage. Around November 1990, Togashi started producing YuYu Hakusho, basing the series on his fascination with occultism, horror movies, and an He modeled the series on his fascination with the supernatural, his love of scary movies, and the mythology of Buddhism.

**Synopsis:** Yusuke Urameshi, a teenage miscreant, is hit by a car while attempting to save a child's life in the process. He is given the title of Spirit Detective during his time in the afterlife and is tasked with looking into incidents involving apparitions and demons by Koenma & Botan. The other main characters in the story include fellow miscreant Kuwabara,silver haired fox demon Kurama and Hiei, with whom Yusuke travels. The focus of the series shifts from a detective story to one that is more centered on fighting as it goes along.

## Terminology

**Test For Resurrection:** When humans die ahead of schedule in unforeseen circumstances,(happens once every 100 years) this usually takes 120 years( Yusuke was an exception). The is a test based on the character of the soul where that uses energy emitted by humans to determine whether the egg( spirit world beast which is a reflection of the soul) into an angel, while if u have a demon which in this case kills you when u come back to life,

**Dark Tournament:** The Dark Tournament is a cruel martial arts competition sponsored by wealthy human criminal lords that attracts the attention of some of Spirit World's most terrible demons. According to Younger Toguro, wealthy human gamblers and business owners attend the tournament for the sake of betting and amusement from the bouts, whilst demons attend for the sake of blood and the chance to wish for anything they want.

According to Kurama, the concept of mercy has never been a part of the event, which means that any strategy to defeat the opponent is acceptable. According to Hiei, the only rule of competition is that the strongest combatant wins.

**Demon World Tournament:** Yusuke Urameshi devised and funded the Demon World Tournament  as an alternative to the all-out conflict projected to erupt following the death of Raizen, one of Demon World's three major powers. The conditions are as follows: anyone can participate; everyone must leave all former kingdom attachments; and finally, the winner of the tournament gains absolute power over Demon World and can do whatever he or she wants for three years, while all Demon World inhabitants must obey the winner's bidding.

**Spirit Detective:** Spirit Detective (Reikai Tantei, "Spirit World Detective") is a spirit world agent that pursues after renegade demons who jeopardize Earth's peace. This job is granted by Koenma.

**Barrier:** The Barrier (kekkai) is a net-like energy barrier built by the Great King Enma that separates Demon World from Human World and is located in the pseudo space. Only demons of the B Class and lower can travel through it. A more stronger net would be created, but net energy was the most easily disseminated energy to cover the distance in the pseudo space.

**Energy Concealment:** Energy concealment is the capacity to manage and minimize a user's latent energy, which can be obtained through intensive training, isolation, and if the user is a skilled martial artist. When in battle or in some dangerous situations, this ability allows the user to release their energy at command. This latent energy can be applied similarly to users of Spirit Energy and Demon Energy. Because it is the evolution of Spirit Energy, it is subject to the same restrictions as Sacred Energy.

**Demon Species:** The original version of YuYu Hakusho was more subtle than the English phrases for demon and spirit can represent. While these beings are commonly referred to as "demons" in English, they are known as yokai in Japanese (or spirit in English). While western demons are often regarded to be malicious by nature, yokai are not (though Yusuke usually deals with troublesome ones). They are more akin to Greek daemons. Many of the yokai in the program are based on real-life stories, such as the Oni who operate in the spirit world or the Ice-Maidens. Some yokai are explicitly referred to as Akuma and Mazoku, which are yokai who are explicitly impish or diabolical. The majority of the yokai in YuYu Hakusho are simply bakemono. a yokai of monster type While the yokai of YuYu Hakusho are not necessarily "demonic" in any manner, they all come from Demon World and are eventually ruled by a Mao (Demon King). The planes or realms of YuYu Hakusho are home to a variety of spirits/demons. Many of them resemble humans and have humanoid characteristics.

**Power Levels:** Power levels are established by a character's strength, stamina, energy, and potential. They are determined by a person's ReiKi or Youki levels. They are initially seen in the Punching Machine during Genkai's Tournament, and then again in the Three Kings Saga, when they are read using devices unique to Yomi's realm. Genkai's objects test several facets of a person's Reiki. Her punching machine displays the person's Rei hitting power/attack power, and the karaoke determines how much Reiki they have. Yomi's devices are specifically developed for use on demons, and their entire power is calculated by adding their stamina, offensive power, special powers, and defensive power.

**The Atavism of the Mazoku:** The Atavism of the Mazoku ( translated as Demon Race Great Atavism) occurs when a demon deliberately renders its genes recessive until that code can express itself in a descendant strong enough to succeed it, effectively creating a demon sleeper agent. This is, of course, an extreme example.

**Physics:** The term psychic refers to an individual who possesses supernatural abilities and can utilize Spirit Energy (or Demon Energy in some situations) as well as heightened spiritual awareness to see ghosts and demons, telepathy, molding energy, and manipulating objects and/or matter. In the English anime, psychics were either fighters like Genkai who gained such abilities through rigorous martial arts training, people born with abnormally high spiritual awareness like the Kuwabara siblings, or people who gained their powers as a result of the Sensui Seven's Gatekeeper opening the Makai Barrier.

**Territory:** "Territory," a phrase introduced in Chapter Black Saga, is a power used by most Psychics that allows their supernatural abilities to work within a specific area. Those who find themselves within a Psychic's Territory become vulnerable to his/her powers and must abide by the restrictions of that particular Territory.

**Sacred Energy**: Sacred Energy (Seikki) or Holy Aura in the Viz Manga is a rare trait. The evolution of Spirit Energy is considered to be the most sacred and powerful of all energies. Sacred Energy is referred to by Koenma as the "Ultimate Aura," the utmost level of power that not even Genkai, who mastered the Spirit Wave, can achieve. Sensui, as Shinobu, awakened this energy during his 10 years of solitude, which is the outcome of his unique intrinsic gift (even all his seven personalities). Shinobu pointed out that Yusuke wouldn't be able to awaken Sacred Energy even if he possessed energy several times his own.

**Spirit Energy**: Spirit Energy (Reiki, or Aura in the Viz Manga) is the energy that all humans possess. If utilized appropriately, it is extremely strong and may be wielded by any spiritually conscious human. However, the intensity of the energy differs from person to person. It differs from person to person in the same manner as fingerprints and voiceprints do. Energy can be transformed into weapons, used to enhance body strength, and utilized to heal. In the English dub, Spirit Energy was initially used as a general term for energy, including Demon Energy; this is a mistake because it is unusual for a demon to possess Spirit Energy; however, this is eventually addressed in the Chapter Black Saga's later episodes.

**Life energy**: Life Energy is a last recourse for demons and humans who have exhausted all other alternatives; using all of it destroys them. When Yusuke vanquished Suzaku and at the end of the Four Saint Beasts Arc, it was employed. Kuwabara transferred some of his own Life Energy into Yusuke, allowing him to live; they both survived, albeit Kurama and Hiei had to carry Yusuke and Kuwabara home on their backs. Kuwabara almost used it in his fight with Risho. He was about to sacrifice himself, drawing the match and winning the round for his team, but Yukina interrupted him at the last second, allowing him to regain his spirit.

**Demon Energy:** Demon Energy (妖気, *Yōki*) or Demonic Aura in the Viz Manga is harnessed only by demons. Its strength varies greatly on the user. As stated by Younger Toguro, Demon Energy is not always as strong as Spirit Energy, but it gives a pleasurable sensation. It is also often more potent than Spirit Energy, due to demons usually possessing far greater amounts of energy than humans. In the earlier episodes of the English dub this was mistakenly identified as Spirit Energy as well (particularly during the Spirit Detective and Dark Tournament sagas), though even the Japanese version accidentally refers to it as Reiki once or twice.

**Demon World**: Demon World (Makai) is the realm of demons. It is a planet that King Enma locked off with a formidable barrier that barred any A Class or higher demon from crossing. It was ruled for many years by three kings: Toshin Raizen, Mukuro, and Yomi, though not in the literal sense. Until the inception of the Demon World Tournament, the victor would combine Demon World under him/her as the supreme ruler, each area had its own separate rules as created by its rulers. Raizen, Mukuro, and Yomi are known as the three kings because they have the most influence and strength among all the kingdoms in the country to strike a deal with King Enma to let Yusuke Urameshi, Kurama, and Hiei to return to Demon World.

**Spirit World/Underworld:** The world to which sentient beings (demons and humans) travel after they pass away is regarded as the Spirit World (Reikai), or Underworld, in the manga. It is sort of a station in between worlds where a soul's fate is decided; it is not comparable to Heaven or Hell. The Spirit World, according to Kurama, is truly a complicated web of realms, however it is more closely linked to Human World than to Demon World.

**Spirit Classes:** All beings in the three worlds, including those in the Living (Ningenkai) and Demon Worlds (Makai), are classified in accordance with a system in the Spirit World (Reikai) . These rankings are determined by a being's physical prowess (such as speed, strength, etc.) in addition to the quantity of spirit or demonic energy they contain. From weakest (E-class) to strongest (S-class), they are divided into five classes, with three tiers (upper, mid, and lower) frequently detected in each class.

(E Class) The weakest of all classes. Demons of this strength aren't particularly strong or intelligent, but they are incredibly violent. Their strength, however, is slightly greater than that of the typical human. This category encompasses the majority of humans and Spirit World people.

(D Class) The next-lowest class. They, like E-class demons, aren't usually extremely clever (with a few exceptions) or exceptionally powerful, but their strength and endurance are superior to that of an average human. However, in comparison to most demons, they are extremely weak. Hiei was an Upper D-class when he first battled Yusuke, according to Koenma. The world's strongest normal humans with spiritual awareness are all D-class.

(C Class) For most demons, this is approximately average strength. They are far more powerful than the E and D classes, but their might pales in contrast to the more powerful classes. These demons are highly frequent and plentiful in both the Human and Demon realms. These individuals are capable of incredible feats of strength and speed, much beyond what even the strongest normal people are capable of, such as moving faster than the eye can follow and withstanding acid falls. This category includes the Saint Beasts (Genbu, Byakko, Seiryu, and Suzuka), as well as the majority of the demons in the Dark Tournament.

(B Class) This class marks the beginning of the upper class demon strength, where the difference between the previous courses is absolutely great. Although B classes are significantly more powerful than C classes, they cannot compete with the higher levels. In most circumstances, this is the strongest class of demon found in the Human World, as any higher class cannot cross through the Keikai barrier net that separates the human and demon worlds. Only when the Barrier is down or a higher class demon wears an organic item that reduces their power, as Hokushin did when he first encountered Yusuke, would a higher class demon be found in the Human World. Koenma claims that younger Toguro, he was an upper B-Class demon when he faced Yusuke at the Dark Tournament.

(A Class) While the Keikai barrier is up, the second to highest class, A-class strength level is almost exclusive to Demon World; the only exceptions are if a human attains this strength, a demon attains this level in Human World, or the barrier is destroyed and demons with this power can traverse to the Human World. Prior to the removal of the Keikai barrier, A-class demons could not travel between worlds without assistance. They are extremely powerful and rare in the Human World, but relatively abundant in the Demon World. They are, however, incredibly weak in comparison to the might of an S-Class demon; so weak, in fact, that they are deployed as mere foot troops for the Three Kings. King Yama (Enma) and his Special Forces Defense Force, Yakumo, and the Meikai gods are all members of this class.

(S Class) S classes are the most prestigious (the pinnacle of power). They are so powerful that even a "low" S class can completely destroy a big area. They are uncommon in the Demon World, with only around 20 known by name. Even an A-class student is unlikely to reach this level, however it has been noted that a strong A-class student can reach upper S-class in less than two years. This was said to be Sensui's entire power, as well as Yusuke's when he awoke as a demon. During the Three Kings tale, Kurama and Hiei both attain the S Class.

(Upper S Class) The series' most powerful known level of power. Demons of this grade are extremely rare, with only Yomi, Mukuro, Raizen, and Raizen's former sparring partners having attained this level. However, Kurama implies that other demons of similar quality may lurk in seclusion within Makai's lowest depths. Demons with this strength are reported to have godlike power and to be so powerful that they cannot remain within Ningenkai without disrupting the fabric of reality. Anyone having a power level of more than 200,000 is considered Upper S Class.
