Why do demons keep mentioning how weak/frail humans are? I mean, look at Kuwabara, he got impaled, nearly had his neck snapped in two, and having every bone in his body shattered in pieces, after all that today he can stand casually as though nothing happened, Yusuke's a half-demon he got down and was temporally crippled after just one freakin hole on his abdomen. Hell, Sensui was the series' first S-class demon and owned Team Urameshi by himself, he has the strongest type of ki in his disposal, three human contestants at the Dark Tournament effortlessly killed several demons without so much as breaking a sweat. Hiei is a pure demon and goes down after just one damn hit, Kurama is a demon possessing a human and he took beatings about as worst as Kuwabara. The latter can detect a fucking earthquake, are they envious of their good life style or are they just plain racist?
Kuwabara is exceptionally resilient. He can take a beating like no other character in the series, and his strongest asset seems to be an absolute refusal to hit the ground. This is probably rooted in the fact that he's spent the better part of his life having Yusuke beat him half to death; to hold other humans to Kuwabara's high standard of endurance, resilience, and pain tolerance is about as unfair as expecting all humans to be as clever and versatile as Kurama.
Hiei captures Keiko as she leaves school. However, Yusuke only realizes she's missing after Hiei contacts him...in class. He doesn't appear to be in detention, and wouldn't he have noticed if she was gone overnight? Did she actually skip or something?
This troper was under the impression that Keiko was captured after school ended, Yusuke only noticed during a that time he was held after school hours to get lectured at for being....Yusuke. After all it is about sunset or so when he finds the place Hiei is holding her, and the battle, correct me if I'm wrong-holds out til nightfall.
On the subject,what happened to Hiei's "Jagan" form where he goes all green and has all those eyes? That would've been fairly powerful if what was said was true.
The transformation costs a lot of energy, therefore fairly unreliable. Also, it didn't help in his fight against Yusuke, and opponents after him were way stronger.
Dragon of the darkness flame uses far more energy and has killed everyone that has tried to master it in the past but he still uses it risking his life if he does it messes up or doesn't use enough energy and knowingly sacrificing his arm to use it. It's because hurt and blind one of those eyes and his Jagan will be temporarily blinded until he has time to heal and recover his energy, and post Jagan eye Hiei needs to use his Jagan eye in order to use any of his fire powers, which means he might not be able to use fire powers while in the eye form so he has to pick and he apparently prefers fire. Hiei is also a protagonist so they don't want one of their hero's looking like some kind of monster that children would run from, that is the reason from the writer's stand point to not have him ever change into that form again, but not looking like a monster that children run from in the street could also be Hiei's reason for during the four saint beasts he doesn't need it and after they rescue Yukina he see's himself differently and doesn't want Yukina to know he's her brother because he's ashamed of the crimes he committed and doesn't want her to know/likewise be ashamed of him. And finally the more powerful the demons in the series become the more human they look with the strongest looking almost exactly like a human but with one or two small non-human characteristics like having horns or pointed ears and claws. Or maybe he can still use his fire while in the Jagan form but the Jagan form is like Gohan's (from DBZ) SS 1 such as the use of that form actually restricts his power and makes him weaker than he is normally.
Okay, so Yuusuke had a big wake and presumably funeral. He's Obviously Dead. The whole resurrection thing happens and....nobody seems to pay it any mind. What, do people in the YYH-verse regularly come Back from the Dead?
He probably said he was in a coma or something
Keiko and his mother are in on it, Kuwabara is familiar with weird spirit stuff, and the teachers clearly do figure out something weird is going on, but they don't much care why it happened, they're just irritated that, "He's like a cockroach; he just won't stay dead." The other students are afraid of Yusuke because of the rumors, so they probably assumed he was back Like a Badass out of Hell, and they weren't interested in finding out details, lest he do all kinds of bad stuff to them.
It's not like his death was a small thing that could have been ruled off as a rumor or misinformation. He was gone for several days, there was a huge public funeral with lots of attendants. The little kid that he died to save were there. And yet no one thinks it odd that he just "got better" from being dead?
They probably DO think it's weird, but the fact that no one directly confronted Yusuke about it doesn't mean that no one's talking about it. Yusuke's not a good kid; he's a violent thug that all the other kids are afraid of, to the extent that his whole relationship with Kuwabara was originally founded on Kuwabara trying to build his rep by taking down the baddest kid in school. Yes, his death was totally public and no one could have missed the fact that he died, but the fact that he's back isn't something that anyone's going to be willing to ask him about. As was said above, a kid like Yusuke coming back just means that Hell couldn't hold him, and nobody's willing to push any further than that.
In the manga, it's explained that Atsuko's contacts in the yakuza bully the teachers and shop-keepers in town to simply not talk about it.
They could had also simply passed off a miscalled death, say he was only temporary dead when the paramedics check him, then in a coma the rest of the time.
Which is actually true to an extent, since Koenma gives his body a temporary pulse during Yusuke's trial.
Koenma alters people's memories so that the people who would say "wtf" when they saw him walking around would forget he had spent the better part of the past week dead. (i.e.) his school principle who defened his honor at his wake.
The Rescue Yukina arc as well as the details of Hiei's origins raises a lot of questions. Hiei was just a few hours old or a day at most when he was thrown off the Koorime's village. When he finds the village using his Jagan, he speaks to Rui, who tells him about his mother, and to his surprise, his sister. This was long into adulthood (for his age as a demon) so where did that one flashback where he's following Yukina as a child come from? How did Hiei know what his sister looked like? Rui didn't tell him anything but her name, so how was he supposed to identify her? And when Koenma gives Yusuke the rescue Yukina assignment, how the hell does he even know that Yukina is related to Hiei?
Can't explain how Hiei knew what Yukina looked like (maybe the Jagan gave him the ability to find out? I dunno, it's powers were never really explicitly covered in comprehensive detail, as far as I remember.) but Koenma is a ruler. He has spies and investigators who aren't limited by mortal means. Then again, what means they actually have at their disposal were never really covered either.
I think Koenma knew because he got a good look at them. Come on, look at Hiei and Yukina, the face is the same! That, or Koenma just did a dna analysis. After all, he got Hiei imprisoned for a while, and in the manga he mentions knowing about Yukina from bird spies, and guess what Yukina keeps in her cell while being imprisoned by Tarukane?
The ice maiden clan is very secluded, Yukina was apparently the only one somewhere else. Also I think the kids scene was anime filler.
Hiei knew since birth he had a sister he was a hyper intelligent and aware infant, and whenever an Ice Maiden gives birth she sheds a tear for her newborn child but not out of sadness the tear freezes and is different from the regular gems made from their tears and is then attached to a string and given to the child (who normally wear them around their necks) these gems also contain in them some of the mother's demon energy. Now whenever Hiei and Yukina were born their mother shed not one but two tears one for each her children. Hiei wanted the Jagan eye partly to find his gem and partly to find the village. He used the Jagan to look for the emense demon energy inside of his gem but still couldn't find it, Yukina however still had hers on her but swallowed it to prevent Tarukene from taking it (Hiei couldn't find his because his was in a similar place). After going to the village and learning his sister's name he was either able to find her because knowing her name allowed him to see her with his eye, because after learning her name he was able to remember what her energy felt like (although unlikely he would forget given what he remembered so he would have been able to tell she was not in the village if he knew what it felt like), or my favorite and in my opinion the best reason after finding the village and not being able to find his gem he searched for his sister's gem's energy with his Jagan eye, located it, and found it to be in the possession of a young Ice Maiden wandering the world with the same crimson red colored eyes as him, he even found her once before Tarukene kidnapped her but was to afraid to approach her and hid in the trees, and after that would routinely check in on her with his Jagan when he was not other wise preoccupied.
I can't believe no one has mentioned this. The whole "Youko Kurama"/"Shuichi" identity. The anime makes it seem like "Youko Kurama" is a name, when "youko" literally translates to "demon fox". Kurama is his demon name, Shuichi is his human name. Also they make Kurama... talk to himself? This is also wrong, he doesn't have two personalities. He has one, and only one identity. How else would he have been aware of his past and his powers if he wasn't fully conscious when he took over the human's body?
Ok, I can NOT believe no one has mentioned the enormous walking plot hole that is Kaito. For those who forget Yu Kaito is one of the humans with territories, his involves word taboos, those who violate them have their souls sucked out. This is pretty powerful when you take into consideration Kaito is easily the second smartest character (smartest when it comes to literary related items), however it easily makes him the most powerful person in the series when you learn it also prevents ALL violence (for him and others, not counting his taboo) and the word taboo can be changed whenever he damn well pleases. The sheer amount of versatility this ability has is mind boggling. Why Yuusuke and Co don't use this character more (he becomes their friend shortly after stalling the group) is just jaw dropping. Every single demon/human/whatever in the entire series could be easily taken down by Kaito if he would simply engage them in words and switch the taboo midway through the sentence, even if the person he was fighting knew enough not to talk to him, one of the others could easily toss rocks or something at them and duck back in the territory when they retaliated if not just attack from inside it. This is taken to even further measures when you realize they usually leave him behind for fear he would get hurt, if anything you would want him with you at all times. Even if he couldn't move while maintaining his taboo (he can, and does) you could simply have him stop and set it up to provide a safe haven or bar a passage. He even survives the arc and in fact is not only an active participant, but is arguably the most important secondary character in the entire series, they would of never beaten the Gamer King with out him. It just stuns me that he was written in his current form, his ability is so powerful that even the author tried to get rid of it, every single character seems to forget he can do anything other than word problems the moment he is defeated (by playing on his pride and using a trick no less).
Maybe there is some setup involved in making his territory.
It could be many things, such as the above "set-up time" idea. It could also be that his territory is not as unbreakable as initially demonstrated, certain forms of demon energy might be able to counter it (such as Kuwabara's dimensional sword, possibly even Sensui's saint energy) and it was largely to show the territories as a new aspect of spiritual powers. As well, the guy couldn't change the rules on a whim and was subject to his own conditions.
There's two reasons I can think of. Near the end of series, the main cast was seriously strapped for time. Kaito's powers, while useful, would probably hurt them more than it would help. And in the final arc, I doubt the big bad demons would have taken kindly to a human walking around. (Kuwabara only went in because it looked like the world was gonna end)
Plus, he's not exactly invulnerable outside his territory. A guy like Sniper or even someone fast enough could kill him off early, once they know to avoid him.
There's also no reason for him to risk his life on the demon realm.
Am I the only one who thinks Yusuke's mom and Kuwabara's sister look and sound similar? Also, have they been in the same room together?
No, you're not. I have mistaken Shizuru for Atsuko a few times. They really are drawn too similarly.
Correct me if I'm wrong, but I seem to recall Atsuko going with the other girls to the Dark Tournament in the manga instead of Shizuru. Maybe this was a case of Suspiciously Similar Substitute to create Sakyou/Shizuru?
The first few times I saw her I thought she was his mom.
Raizen. I know he's one of the species of youkai that supposedly have to eat humans to survive. But really, when you get down to it, meat is meat. Couldn't Raizen have eaten animals or something like to tide him over?
This has bugged this troper too! They never elaborate on why he can't eat other than he doesn't want to eat humans anymore. He could easily go vegan too if he wanted. It's just....makes no sense.
The only logic I can find behind any of this is that in order to sustain his god-like power Raizen needs an enormous amount of calories and possibly the spiritual energy of his victims. Though what makes this odd is that you would think that your spiritual energy would be independent of your normal biological processes, Raizen certainly doesn't look like he has been starving himself for hundreds of years as he is tall and muscular and his spiritual energy is greater than that of Yusuke as he is on his death bed. Raizen should never have lost any of his great power had he simply been training himself all that time and any calories he would need for his physical well-being could easily have been met had he eaten a wild animal or fruits and vegetables.
Personally, I think they need to eat humans because of a specific quirk of the way their bodies function. They burn up not just the body, but the life energy and spirit energy in the body. Meaning, in short: no humans, they get weaker. I think that the only thing Raizen could eat for sustenance was humans. He's not like a human in any way, his body works way differently. If you think about it, Raizen serves as a rather good example of why the humans feared and hated demons. Beings like Raizen don't just have an appetite for... Different fare, they can't survive on anything else. Raizen was massively powerful, even at the time of his death and I think that was his absolute minimum baseline power, his maximum was probably equivalent to both Yomi and Mukuro simultaneously with him playing with them for no reason other than to have fun wiping the floor with them. If you take it a bit further, his decision not to eat humans caused a catalysis in Yusuke: his Mazoku genetic half was immune to the need for humans; Raizen needed them to live but his refusal allowed his sun to avoid passing that threshhold. Sorry if this is a bit complicated. As a TL;DR: Raizen needed three types of energy, not one. It isn't calories, it's the body, life energy, and spirit energy that his body burns in tandem to produce massive post-nuclear levels of power that would be World Breaker power in our world.
Perhaps once a demon eats a human they can no longer survive on any other sort of sustenance.
Where does Yomi get all of the humans that he eats?
Yusuke was in Demon World for three years, correct? What did he eat in that time? By the looks of things there are no ordinary animals in Demon World, and it's doubtful that Yusuke would become a vegetarian.
I am pretty sure demonish animals live there he could feast on, or maybe Raizen's men brought Yusuke food from the human world to eat.
There are monstrous beasts around, by then his stomach was strong enough to digest even them. That, or he pulled an Hiei and ate anyone idiot enough to try and kill him to make himself a fame.
In the anime at least, Yusuke asks from tea and treats from Yomi and he provides themm and the demon realm also has sake, but even so he's a demon now, and it doesn't look like all they eat is humans or each other.
In the "Dark Tournament Saga", Why does Shizuru Kuwabara cry for Sakyou, but not her brother?.
According to Shigure, his sword is made from the bones of wild oxen who roam Makai. So while not shown, obviously because it wasn't important, there must be food in Makai. Yomi's city Gandara seemed more advanced than anything on Earth, so Makai isn't that primitive. Juri was even working in what seemed like a restaurant.
She knew her brother was faking it?
She does cry for him. When Kuwabara first gets impaled by Toguro, everything goes silent, and you see her burst into tears.
Poor, poor Kuwabara-kun. He is obviously the kind of person who believes in the heartwarmingly romantic "come home to after a hard day's work with his adorable wife smiling at him and his equally adorable children running to hug him" happy ending.But the franchise explicityly states that unless a Demon is a relationship is of A-Class Power, no children will EVER be born even if Yukina-chan returns his feelings and no matter how hard they try. Kuwabara is smart enough to get into a good university, so he should be more than aware of the fact. Coupled with the fact that she will most certainly outlive him and probably STILL be as small and cute on the day he dies as the day she met him, a marriage with her WILL be a futile and meaningless exercise that WILL end in tears for both of them like the one between Connor and Heather Macleod in Highlander. So why would he still devoted his life to her (adorable and sweet as she is) wish to start a(n ultimately meaningless) family with her if he is aware of this?
Where does it explicitly state this? That, and he's Kazuma Kuwabara. There's nothing else to it.
I don't remember exactly when, but in one of the explanations about the avatism thing in the anime, it's mentioned that only A-Class and above youkai can breed with humans. That said, Hiei was an A-Class demon very young, and only got knocked back down because of getting the Jagan surgery. It's possible that Yukina is more powerful than she appears, just not inclined towards combat, and if she's not already an A-Class, then she could become and A-Class.
Then he can settle for raising Yukina's parthenogenetically conceived daughter as his own. He may not be able to impregnate her, but she'll still conceive spontaneously at age 99-100, and given the relationship between human and demonic life cycles, she's probably in her 80's during the series.
The above assumes that ice maidens don't have a longer pre-pubescent period than their ovulation cycle. 100 years doesn't seem to be very long for youkai. It's possible that Yukina, and therefore Hiei, are a few hundred years old but just haven't gone through enough of youkai puberty for Yukina to be of childbearing age.
Re: having children... if Yukina's mother can become pregnant by a fire demon, who's to say that she can't have a child with a human? Considering how Hiei came out, it would be interesting to know what the result would be.
Demons can breed with humans and there were even half breeds on the manga, what you need to be A class or above to do is activism.
Sensui calls Yusuke an immortal, and being that Kuwabara has a different kind of spirit energy than Yusuke or Genki who are human (Kuwabara's is orange not blue) and also unlike Yusuke develops an attack that uses a different type of energy than his normal spirit energy (the dimension blade) its not out of the question to say his abnormal spirit energies will cause him to live an abnormally long life, possibly even living an extraordinary abnormally long life as his spirit energy causes him to heal and stay in his prime far lounger than it should. Plus Yukina is a powerful healer that could keep him around for a while and Koenma owes him... a lot he saved the world countless times even though it wasn't his responsibility.
On that note, did the series ever make it clear whether Yukina was a natural Ice Maiden or if she was also half-fire demon like Hiei?
Considering Ice Maidens have a single child once every century, conceiving the child alone, it isn't hard to believe Yukina didn't inherit any of Hiei's father's genes.
She has red eyes like Hiei, and unlike the other Ice Maidens.
That is a really good point, and possibly the reason why she is not cold and frigid, like the other Ice Maidens. is that the fire inside her prevents her heart from freezing over, much like how Hiei is not affected by the bitter cold of the village or the ice of the saint beast, because regardless of his fire if that attack was meant to freeze his limbs solid he should have at least gotten frostbite, is he has an extreme resistance to the cold which he inherited from his mother.
Where is it said that Hiei's father was a fire demon? Because what Hiei said once that because of his origin he was the opposite of the Koorime, fire instead of ice. Yukina may have just become disillusioned with her kind and decided she didn't want to be like them
This may seem a little silly (certainly not a plot-related question), but why is Yusuke's last name Urameshi pronounced as "Yur-a-meshi"? I have watched enough anime to have a very basic understanding of Japanese pronunciation, but wouldn't it be pronounced as "Oo-ra-meish"? Is that a dub error, or is that really how it's pronounced even in Japanese? (Note: I have not watched the Japanese dub)
It is indeed pronounced Oo-ra-meshi in the Japanese dub.
Anglocized by/to fit the taste of the english speaking voice over cast.
Mmkay, so... Hiei. He gets exiled and all that, so eventually he goes to Shigure to get a Jagan eye. The price for the eye is his story and also that he can never tell Yukina he is her brother, isn't it? So then he goes to the ice place (I haven't seen this in a while and can't remember what it's called) and... finds out he has a sister named Yukina. Does anyone else see anything wrong with this?
Hmmm, maybe he already knew he had a sister, but thought she might've been at the island; and after he found out she wasn't there, that gave him the incentive to search for her because it's only then he's been told she's in the human world?
Hiei remembered his sister's existence. He just never knew she had been kidnapped.
Hiei was aware of all that was happening to him before his exile and was aware of his sister all his life (he just didn't care about his sister at all prior to receiving his Jagan) but he gets his Jagan to try and find his mother's frozen tear he had been given prior to his exile and to find the village of his birth to take his revenge on them for trying to kill him. Once at the village he meets his mother's closest friend in life who also raised his sister she then tells Hiei his sister's name is Yukina and Hiei decides to find her. And as payment for teaching him his sword style Hiei is not allowed to tell Yukina he is her brother.
Alright... We know that demons are not allowed to kill humans for any reason right? And part of the suspence of the "Rescue yukina" arc was that as much as we want that bastard Tarukane to die horribly, We don't want Hiei to get severly punished, Right? Well that would be fine, except when Hiei finally shows up at Tarukane's door, he runs in and kills 2 HUMAN guards and Tarukane's butler! Shoulden't he have been punished for that? Was Tarukane REALLY that special?
Hiei never intended to kill Tarukane, or he would have killed him with the first punch. He was just torturing him a little before giving him to Yusuke. Same thing for the guards and the butler: he just knocked them out.
Hiei wanted to kill Tarukene but is on probation for stealing the darkness sword and running amok in the human world (Kurama too) and part of his probation is that he can't kill any humans regardless of their crimes, he also can't leave Yusuke's town which they all do in the chapter black saga so go figure.
At the begining of the chapter black saga botan gives him a pardon in exchange for going to save urameshi
Also, don't forget that the guards Hiei encounters upon first entering the fortress are implied to have been knocked out by Yusuke and Kuwabara, though Hiei not killing the guards surrounding Tarukane is a bit of a headscratcher. Maybe he just didn't view them as worthy opponents, so he let them be. Then one might wonder why he did basically the same thing when he first appeared, but Hiei wasn't killing them, merely turning them into slaves. Perhaps he views killing as a bigger crime for the weak?
Something that's bugged me for a while; in the Dark Tournement arc, after Kuwabara earned a CMOA by beating Elder Toguro, he confronts Yusuke about not telling him about that important, spoilery plot point, believing that him and the others didn't tell him about it because they think he's a joke. Kurama tells him that Yusuke didn't tell him or Hiei either, and that they had to sense it themselves. It's a very emotional and one of my personal favorite scenes, but I have to wonder why both Hiei and Kurama were able to sense it if Kuwabara couldn't. A big deal was made of his exceptionally high spiritual awareness during the Ghost Yusuke arc. Even Genkai seemed genuinely impressed by his score in the spiritual awareness game at her tournament.
Note how in the following season the Chapter Black Saga Kuwabara temporarily loses his powers, only to develop a new sword technique that saved his life when the bad guys attacked him and his friends. Genkai theorized that Kuwabara's spiritual awareness was so powerful that it developed that new sword technique as a response to what it knew would be needed to defeat that season's villain, the loss of his powers was a temporary side effect of that new power developing. It is possible that during the Dark Tournament saga that said power was already beginning to develop which severely weakened his spiritual awareness. This is one possible explanation. However stories sometimes use dramatic convention to spice up the plot even when you take into account that the characters all have the ability to sense power levels. The dramatic impact of Kuwabara learning the truth about Genkai's death from Toguro instead of sensing it himself, is the equivalent of characters dying in Dragon Ball Z and their friends not realizing it until later or them thinking they were dead when they were still clinging to life.
He had felt Genkai's death. It's just he was too stupid to realize what that feeling meant, while Hiei, Kurama and Shizuru could realize it.
He also couldn't read the situation and tell that everyone was stopping just short of saying Genkai had died, something that even those who didn't sense her passing could likely have done.
He also doesn't get why everyone acts like there's an inside joke whenever he or Yukina mentions about finding her brother, or why everybody goes "sure we'll look for him riiiight Hiei" wink wink "Hiei" wink wink. And when Hiei gets angry at the others for doing these things, which hint at his relation to Yukina, Kuwabara thinks it's just because Hiei is a jerk. Although in Kuwabara's defense he's never been around to hear anything more than "Yukina has a brother."
A more mundance head scratcher from the start of the series, why doesn't the school principle Takanaka fire those two assholes?
Because they aren't entirely unjustified, especially in light of the Japanese educational system. They bring a positive reputation to their school by highlighting exceptional students, such as Keiko Yukimura. At the same time, they're antagonistic and cruel to kids like Yusuke and Kuwabara, because Yusuke is a violent punk and Kuwabara is running a gang; both of them are hurting the school's reputation, and while they don't have grounds to outright expel them from their school, they can make it an unpleasant place for them to be, in the hopes that they will eventually find a different school.
If it makes you feel better, it is heavily implied that the teacher who changed Kuwabara's test score WAS fired, since he never appears again.
Mr. Akashi doesn't seem to show up after that, but Mr. Iwamoto, who, in the anime was complicit with that, appears near the end, talking contemptuously about Yusuke in class while Keiko and Kuwabara are unimpressed with his lecture.
True, and I'm pretty sure Takanaka is the guidance counselor.
Why did Hiei never again transform into that eye-covered "true form" of his? Pride maybe, but he comes close to death in several of his fights; I'd think at that point pride would go out the window.
In the manga at least, not sure about the anime, Kurama stated that all those extra eyes were just illusions.
Perhaps the extra eyes, which mainly serve to paralyze his targets, don't work on powerful opponents?
How did Kurama get away with betraying Yomi the second time? I thought Yomi still had his human family under threat.
Because at that time he was more concerned with Yusuke and Mukuro attacking him if he didn't go along with the tournament idea, and then the power grab. Plus as previously mentioned in the series he's intimately familiar with pissing off Kurama and would likely not risk it again in this situation. Had he won the throne, he might have followed through on his threats.
Everyone was getting in on the whole fighting individually, even Yomi himself later on.
Ok at the end of the series the barrier separating the human and demon was removed and everyone is living peace. but what about the demons that need to eat humans. I mean Raizen died because he refused to eat humans. so would demon who are like him suffer the same fate?
No. Remember, Enki says 'No mischeif', meaning that they aren't allowed to prey on humans for fun. However, plenty of horrible bad guys like the Black Book Club running around for them to grab up. In fact, in one version of Yusuke telling Raizen off he says "if eating humans is what it takes to get a real fight out of you, I'll just round up some really bad ones and force feed them to you if I have to." Effectively, I think as long as they aren't going for good people they'd be fine, and not doing it maliciously but as a natural requirement.
One thing I found odd was Yusuke's attitude when he found out that Raizen's servents where eating humans. I mean earlier on in the series he try beat Gouki to bloody pulp when he found out that he was eating little kids soul. however when Raizen's servents admitted to eat human he simply shrugs and says "food is food".
People change. Yusuke by that point is terribly disillusioned with the hero thing. After Tarukane, the Dark Tournament experience, and everything that happened with Sensui, the whole idea of "Humans are special, fight to protect humanity from the evils of demons" thing is pretty much dead for Yusuke. As far as he's concerned, humans and demons are not so different. Yeah, there are demons eating humans, and there are humans butchering demons for pleasure, and humans committing various sins to each other, and demons slaughtering each other, etc. etc. and Yusuke doesn't really care anymore because that's just life.
That and Gouki ate souls. If you eat a human you kill him and he goes before Koenma to be judged, if you eat a soul the victim cease to exist.
He's basically begun to see life isn't so black and white. Yusuke probably after living with Hokushin for a few years realized even if he did eat humans, he may have been confident he wasn't going after 12 year old Jenny on the swings at the park.
Yes people change, but I don't think this is one of those situations. Yusuke has always had an open mind. But even his open mind has it's limits. With Gouki take notice of what was happening. He was eating souls. Not just any souls, souls of children. Pay attention to who he deals with best besides demons. Children. He saved that kid's life at the beginning and before that made faces to make the kid laugh. It was obvious he didn't like Gouki eating a child's soul, almost like he was utterly offended. Near the end he fights that former spirit detective's kids, but does so in a playful way. Other than it involving kids, he wanted to save them not just from death, but from nonexistance. It was very important to him because failure meant they couldn't even become ghosts. To him it was a fate worse than death. Last thing was that he wasn't eating out of necessity, he was treating them like a delicacy. He understood that if you need them to survive, you need them. He still wanted good people left alone, that's why he suggested getting evil people. I think if put into another situation like Gouki, he would do the same thing, make him spit the kid out.
It also bugs me somewhat that, in light of how things aren't quite as black and white for Yusuke as they were before, that Yusuke's talking with a demon and considering things from their perspective for a moment is considered a Moral Event Horizon crossing by Kuroko. Perhaps Kuroko never experienced anything quite like what Yusuke and Sensui did, and sees all demons as heartless killers, though.
Who were the other two members of the original Team Toguro and what ever happened to them?
Given that it was the Dark Tournament, we can guess what happened to them. We'll never know who they were though...
Why didn't Kido just stop Doctor from moving once he was near him instead of waiting for Yusuke to arrive and stopping his movements?
In the Chapter Black arc - Why didn't Sensui show Kuwabara the infamous Chapter Black video after he captured him? There was nothing stopping him from doing that.
Perhaps he simply didn't think of it, his plan at that point was mostly solid. He'd even planned to have Gourmet eat Kuwabara to take his powers and use them to break the Kekkai. Also, it's stated that the tape is hundreds of hours long (I think? or several hours at least) and there wasn't much time until the tunnel opened.
Also the video doesn't work on everybody, the people it was used on already had their own issues, Kuwabara and the others already knew that not all people are like that, specially after so many self sacrifices for one another.
Genkai, during the tournament to find her successor, doesn't give two ripe shits about the moral fiber of the candidates. Yet she later puts Yusuke through a test, telling him he'll have to kill her to get her power, and when he refuses she says he would have failed if he'd agreed to do it. What if Rando had been it? He surely would have jumped at the opportunity. And she said the training to gain the Orb would normally have taken ten years. So, ten years training Rando, he fails the test, and she kills him and finds a new apprentice? Hoping she doesn't die of old age in the meantime?
