Yukari must hate Lunarians too, considering that she goes through a ton of things just to steal a bottle of sake from them and tick them off.
When someone devises a ridiculously complex Xanatos Gambit for the sole purpose of annoying you, that someone probably hates you. A lot.
Anyways,
here you are.
Thanks!
Yukari and Keine
I was kinda hoping to save this one for later, because it requires delving into just how messed up Maribel became after she turned into Yukari. Still, I've already touched upon Maribel's/Yukari's... mental issues that are pretty apparent by the present day, so I might as well get this one over with while someone is bringing up Keine.
The last thing Renko told Maribel in Changeability was to change dream to reality. Unfortunately, the translation here is a bit rough. Renko either is telling Maribel that they should find the dream world and make it into a place where kids can smile, or that they should make the dream world real by finding it (either way, finding it is one of the keys, since she basically said earlier "I have lots of clues to go find another world. It's the items you gave me from your dreams!"
From this, after Maribel would become Yukari, she'd either decide that she should make Gensokyo's reality into her own in order to be able to change it from a bad dream to a good dream (her other goal, which she states in Changeability), or somewhere along the line she just snapped and forgot the original meaning of Renko's statement and decided "It's my dream, so when I make it to reality, it should be made into MY reality".
Right now, I'm leaning towards the first interpretation slightly, but either way, the end result is the same. Maribel would want to take control of Gensokyo's reality. Now, I imagine originally she probably didn't want to literally take control of it in such a brutal fashion that Yukari/Maribel ended up doing, but originally she didn't have the powers which reached god-like status, either.
Although the rough translation makes it hard for me to fully interpret Renko's statements, and we also never get to see Maribel's reaction, we do know one thing for certain. Whether it was right after she decided to make her dream into reality, or whether it was because of her attaining god-like powers, Maribel appears to have developed "A God Am I" complex as early as when she decided to name herself Yukari Yakumo.
We have the closest thing to official confirmation of the meaning behind her name that we'll ever get in Curiousities of Lotus Asia Chapter 25, when Rinnosuke uses his special ability to discover the meaning of Yukari's name.
http://touhou.wikia.com/wiki/Curiosities_of_Lotus_Asia:_Chapter_25One meaning means borders (duh), and another means "night that hides from the sun" (IE, youkai). It's pretty obvious why Yukari chose a name which held those meanings (she controls borders, and now she's a youkai). And then there's another meaning Rinnosuke found.
" aside from the primary meaning of borders, Yukari Yakumo's name also has the hidden meaning of 'A strong fortress to keep the gods trapped inside'"
It also means "a great many" Not only that, the "many" refers to the stars in the name, and because the stars are the ones which hide from Amaterasu, they likely refer to youkai.
" "To answer that, all you need to do is gaze up at the sky on a moonlit night like this. Isn't it obvious why the word for the night came to mean 'a great many'?""
(it also means "eight", and Yukari often wears ribbons in the form of an eight. Maribel has worn such a ribbon in one of her official arts, too)
(in some ways, Yukari's name is also a tribute to Renko, since Rinnosuke at the end states the name is heavily based on numbers and Renko's specialty was numbers)
...back on topic, which is Yukari's developing god complex. Well, at least in my opinion, once you start naming yourself "Fortress to seal the gods and the many", you're probably in need of a psychologist.
Of course, if anyone suggested this to Maribel, she'd just reply "I AM a psychologist." (Changeability states her major was Relativity Psychology)
At any rate, the end result is a nutjob that wants to claim Gensokyo as her reality.
With that, we can move on to Keine.
First off, let's start with the most obvious part.
Keine's history powers don't work on Yukari. This is officially confirmed 100% beyond a doubt here:
http://touhou.wikia.com/wiki/Imperishable_Night:_Boundary_Team%27s_Scenario_1Keine: "Humans never settled here in the first place."
All I did was make it look that way.
I'll protect the humans from this ill-omened night.
Yukari: Hey, you know.
I do see the humans as usual though.
This little trick of yours isn't useful at all.
Keine: ! What exactly are you two?
Reimu: Don't worry. It's invisible enough to me.
Keine: Uu. Your pity isn't helping.
Keine's ability to hide or devour or whatever to history clearly doesn't work on Yukari. The question is, WHY? As we've gone over, Yukari's border powers don't appear to be able to control time.
Before we can understand why Keine's powers don't work on Yukari, we need to analyze exactly what Keine's powers are. In Imperishable Night, she says she hid the history, but that's pretty vague. And how does that work, anyways? How does one "hide" history? Akyu explains it in Perfect Memento:
http://touhou.wikia.com/wiki/Perfect_Memento:_Keine_KamishirasawaThe history of Gensokyo is that which is created by her (*2).
Speaking of history, things do not become history merely by happening.
Things do not become history unless they are made history by someone's hands.
She can fabricate history that didn't happen, or conversely, erase from history incidents which actually did happen.
History is reality, seen from a single point of view.
2: Her powers have no effect on the histories passed down by the Hieda family. Thus, over time it becomes not her history, but ours.
Now, the key word here is REALITY. When Keine changes history, she changes reality, albeit "seen from a single point of view" (which means the humans don't realize she's erasing their history and can act as normal, but Reimu can't see them. And yet, Yukari is immune to this and can see the humans as normal)
Furthermore, as stated in the footnote, the true key to controlling Gensokyo's history (and thus Gensokyo's reality) is the Hieda family, not Keine. Over time, the history that Keine creates (while a were-hetaku) becomes owned by the Hieda family instead, and at that point, it's no longer Keine's.
http://touhou.wikia.com/wiki/Perfect_Memento:_Memorizable_GensokyoAnd look who's dropping by to change the Hieda family's history. Why, it's our very own Miss god-complex "I will change my dream into my reality" Yukari Yakumo, herself.
(short summary of the comic: Yukari drops by Akyu's house to edit the final draft of Perfect Memento in order to make it "match reality".)
"After all, I represent Gensokyo's reality. It wouldn't do for a memory not to match reality." ~Yukari to Akyu about why she should be allowed to edit Perfect Memento
Also, in Memorizable Gensokyo, Yukari implies she's been doing this since before Akyu's time, too, albeit she might have had to do it in secret before.
"In that sense, I suppose this is our first meeting, isn't it?" ~Yukari to Akyu, Memorizable Gensokyo
The way she said this ("In that sense") implies Yukari's met Akyu's previous incarnations, which thus implies Yukari's been editting the Gensokyo Chronicles ever since they were created in the first place (we know for sure from Yukari's article that Akyu's very first reincarnation ran into Yukari even before Yukari had a name)
And yes, Perfect Memento definately has Yukari's lies. I'll go into the lies that Yukari put into Perfect Memento later. It's pretty neat. But fortunately, Akyu isn't stupid. She states in Yukari's section that she doesn't trust Yukari, and she's marked everything that she probably got from Yukari as just a possibility (or at least, most of the things she got from Yukari that I can tell). However, in the end, Yukari's edits still made it into the final edition, even if with disclaimers. And people tend to believe things even when those things are disclaimed in my experience ("I read it on the internet, so it must be true!"). At least, that's the logic I'm using, but even if I'm wrong, one thing is for sure. Yukari owns the Gensokyo Chronicles, and thus owns Gensokyo's history and reality.
So in short, it can be summed up like this:
Keine's ability works because she owns Gensokyo's history.
History is reality, shown by a single point of view. Thus by owning history, she can also own your reality, and change the reality from your point of view.
However, eventually the Hieda family owns Keine's history instead. Their ownership supercedes Keine's in this regards.
Yukari edits the final drafts of the Hieda family's history articles. Despite Hieda being wary of trusting Yukari, these edits make it in (even if with Hieda's disclaimers).
Thus by the very end of things, the owner of Gensokyo's history (and Gensokyo's reality, which is her goal) is Yukari.
End result: Keine's abilities thus don't work on Yukari.
Super short version:
Yukari to Keine: Your powers to change Gensokyo's reality mean nothing to me. Gensokyo's reality is MY reality. Now, bitch, get out of the way!
(note: The above quote comes from no official sources
...well, besides the last sentence that I stole from Marisa's moment of complete win)
As an aside and as I've pointed out before, in Imperishable Night, Yukari makes it a point to be really mean to Keine for being a were-beast, and then indicates she hates Keine's human face (Something is probably lost in the translation, but Yukari is clearly getting very insulting to Keine and it's mean enough that it makes Keine attack her). This pet peeve of Yukari's likely stems from when she got attacked by a beast youkai while she was Maribel, and Maribel just couldn't forget how the beast had a human face.
I also promised I'd go into Sakuya's relationship to Yukari as well, didn't I? Alright, it's a little out of order, but that's okay. I'll do that for my next post.
