History WMG / YuYuHakusho

It would have been common in the [[ImperialJapan time period]], especially for two children of martial-arts families. It also splits the difference between the Japanese (where they are referred to as "friends") and [[DubText English]] versions of the anime. Genkai decided to split up the arrangement the instant Toguro became a demon.

Because Hiei sees a bit of his sister (the one person he ever cared about for most of his life) in Botan (there's some resemblance after all), and Botan sees the physical and character resemblance between Hiei and Yusuke (on whom Botan seems to have a crush). Basically, a ''very'' twisted take on LovingAShadow...

[[WMG: Some of the characters from Main/HunterxHunter are alternate-universe versions of some of the YYH characters.]]

Note that few (Japanese) humans in YYH have [[PhenotypeStereotype blond hair and blue eyes]]. Also note that he became Sensui's {{Mook}} because he was bullied, and that [[ButNotTooForeign Charlie Dogs]] tend to be the subject of a lot of bullying in Japan. So it is reasonable to assume he has a white mother. His [[FreudWasRight embarrassing codename]] indicates that he was either half-German or ''still'' being bullied a little. (''Seemann'' is the equivalent word in German, and it doesn't have the punny connotations of its English cognate. Though if [[GratuitousEnglish Sensui knows both English]] [[GratuitousGerman and German]], all bets are off.)

* This makes even more sense when you see the OVA music video devoted to Hiei (title forgotten). Near the beginning Hiei find Hina chained, frees her - and she transforms into Mukuro. Yup. She's his mother figure.
** Depends. Then again, OVA isn't canon at all, so it's okay to shoot it down.

[[WMG: Mr. Iwamoto had dirt on Mr. Tanaka]]

Why else would he still stay employed, despite all the horrible things he did as a teacher?

I mean, she doesn't seem strong, right? I mean Bakken knocked her away quickly in the Dark Tournament arc. However, whenever a character in the arc used a power that would destroy the audience/anything in its path, it never went after her (or Juri for that matter). She's apparently skilled with a ribbon (who's to say that she never fought?). And the only time she was getting weak, was when Toguro was opening up his soul vacuums. I mean, she's probably not high-b like Toguro is, but she's gotta be at least a low-b class demon.

The animation is fairly normal whenever nothing supernatural is happening. However, when there are a lot of demons around or when something is powering up (Hiei's Dragon of the Darkness Flame comes to mind) the animation changes. This is because the spirit or demon energy is [[spoiler: messing with the Spirit World cameras that are being used to record Yusuke's life.]]

[[WMG: The reason the animation style changes so often.

He has two new "must defeat" targets: Yusuke (for killing Younger Toguro before he could) and Hiei (for beating him). He starts serving Mukuro to keep a relatively close eye on Hiei, so he can see just how far he still needs to go. Even if he really has reached the peak of his power, he won't stop trying to get stronger, if only so he can challenge Hiei again and die in battle properly this time.

Suzuki tracked down five of them and took his place as captain under the identity of Onji. Then they embarked to reach Hanging Neck Island, won the qualification match... And lost three of the original members when the members of the other teams ganged up on them, at which point Suzuki, Shishiwakamaru and Makintaro forced the two survivors of the other teams to join them under Kuro Momontaro and Ura Urashima's identities.

*** Except that Hiei's hair ''does'' have highlights; they're a dark blue. How that starburst manages to stay more-or-less consistently in place, though...

Excluding the high possibility that Kuwabara dyes his hair, all characters with [[YouGottaHaveBlueHair strange hair colors]] aren't regular humans.

Seaman (Envy): Jealous of other people having "friends" and allies whereas he doesn't. In fact, before his Face Heel Turn, he attacks people who he thinks are weaker than him, going by The Other Wiki.

WhatDoYouMeanItsNotSymbolic It's meant to invoke the worst of the {{Fallen Hero}}es, {{Satan}}. who literally ''is'' a fallen angel. It also may represent, not only Sensui's FaceHeelTurn, but also [[AGodAmI his humongous ego]] and [[KnightTemplar extremism]] (for whatever side he is on).

[[WMG: Yu Yu Hakusho is an universe created by Haruhi]]

Or were reincarnated high-level shinigami to start with, Yusuke getting the help of being from youkai descendance, Kuwabara's family being somewhat related to the Kurosaki clan (Kurosaki = black flower, kuwabara = mulberry field, both have the black field theme going on; also, Kazuma looks one hell lot like Isshin). Kurama is a reincarnated youkai, and Hiei, Yukina, and the other youkai are drifters. Perhaps Chad's powerup would be similar to Toguro's...

Mukuro earned his trust remarkably quickly, and Hiei's non sister related [[PetTheDog dog petting]] involved her. Also they mind melded and Mukuro said "Yours was the first mind to mix so readily with mine own." They both were angry people with screwed up pasts they saved each other from. She stripped in front of him. Hiei expressed a good deal of happiness when she talked about what a chore patrolling would be. It'd be nice to give both of the least happy people in the show some happiness. And they'd make a cute couple. Mukuro "The neighbors wouldn't shut up last night." Hiei, "I'll bring you their hearts."

After [[spoiler: The Koorime exiled him from their island for being male]], Hiei became quite hard-assed as he had to fend for himself at a young age. He found something in common with Mukuro (their pasts), and he finally found a replacement mother in Mukuro since Hina was gone and the rest of the Koorime rejected him. This is also a nicer way [[ShipSinking to let the Hiei/Mukuro ship down]] for [[FanPreferredCouple Kurama/Hiei]] without resorting to CharacterBashing.

Hiei's motivations early in the manga are simple and seem uncharacteristic: He wants world domination. While he was only supposed to be a one-off character, like Kurama, it seems like his motives for stealing the artifacts were completely unrelated to his actual motivation to get to the human world: Finding Yukina. World domination would seriously hinder finding his sister until it was too late (ie. until Torukane's torture became too much and she died.) Kurama, on the other hand, may have been set up as a kind of villain by Spirit World much earlier. Remember, demons had been hearing boogeyman stories about him for centuries. That kind of stigma is usually attached only to the series' Big Bads.

It's shown that Yukina was held captive long before her introduction to the series, and indirectly stated that she was missing before Hiei was introduced. Since it's clear that Hiei cares about her more than anything, so her going missing and be unable to find her would upset him. Likely after searching and searching for her and coming up with nothing made him have a FreakOut and decided to steal the items in a desperate attempt to find her. This might also explain why he acts more psychotic at the start of the series compared to how he acts later on.

* He had a brain tumor. Brain tumors ([[http://en.wikipedia.org/wiki/Glioblastoma_multiforme specifically glioblastomas]]) are known to be slow-growing (even in normal people) and cause personality changes. This would have been very convenient if the tumor started about the same time as he flipped out during the Black Black Club incident, because it would have the possibility of making his SplitPersonality ''worse'' (meaning, if he hadn't had the tumor, he would only have one to two alters instead of six, due to the effect the tumor had on his brain). The reason he was going to die in half a month's time was that the tumor had crossed the blood-brain barrier (as is known to happen sometimes with glioblastomas) and had metastatised to some of his other organs. At that point, medical science could do nothing for him (even though, being ridiculously strong, he could still fight enough to commit SuicideByCop).

The two had met when Sensui was sent to shut down the Black Book Club's demon kidnapping ring, with Hiei actually saving Sakyo from Sensui's homicidal rampage in the hope Sakyo would be able to tell him were Yukina was. As Tarukane had already spirited her away, Hiei was about to kill Sakyo (either personally or by throwing him at Sensui), but the billionaire managed to convince him to let him help. Fast forward ten years, the Reikai finds out were Yukina is, and Hiei, instead of going and murder Tarukane on the spot, reminds Sakyo his promise and demands the means to make him ''pay'' for what he did his sister. Is there anyone here who doesn't know what Sakyo did to Tarukane?

Suzuki tracked down five of them and took his place as captain under the identity of Onji. Then they embarked to reach Hanging Neck Island, won the qualification match... And lost the original Ura Urashima and the sixth member when the members of the other teams ganged up on them, and forced the one survivor of the other teams to join them under Ura Urashima's identity.

* In the same vein as an above entry, Kurama's human genes were probably influenced/manipulated by raw demon energy before birth, thus giving him red hair and green eyes.
* Yukina's greenish hair is probably average for her kind. Hiei's hair is naturally ''vertical'' and has white streaks. All other characters with unnatural colors, like Toya, Shishiwakamaru, and Juri, are demons of various types.

* Botan's and some of the SDF are, obviously, spirits.

* In the same vein as an above entry, Kurama's human form was probably influenced/manipulated by raw demon energy, thus giving him red hair and green eyes.

[[ImColdSoCold Death is Cold]] and life is warm. Healing (restoring life), is a power more closely aligned with fire than ice, and is therefore not native to a Koorime (ice maiden) at all. Perhaps her red eyes aren't the only thing she got from her fire demon father.

It would explain why Yusuke's mother has Yakuza connections- she was the girlfriend of one of their ranking members.

Also, she is Hiei's sister, and Hiei has been a ludicrous powerhouse since literally before he was born.

Same thing with ''Manga/DragonBall Z'' could one reason that demons in the Makai be A LOT stronger than demons in Earth be because the Demon World's gravity is much greater. The manga and anime have proven that the Demon world is much much bigger than Earth and probably more durable too. Sensui said that he couldn't even use 1/5 of his full power on Earth otherwise it would put too much stress on the planet. He could only fight at full power in the Demon World which is another motivation for him to open up the tunnel.
