Everyone who is arguing about whether Gensokyo is real, dream and other stuff, why don't you just stop for a while and have a look at my theory? Well, although I'm still in grade school, I'm quite interested about science, cosmology and all other complex stuff, and definitely, Touhou, as a big cluster of these, draws my interest quite well.
During my free time, pretty much all I does is just looking up some random scientific stuff and Touhou-related stuff, and I eventually started to research the relationsip between Gensokyo and our world, and some interesting result is coming up. (In order to protect your eyes from getting sour from reading all these letters, I will post my theories on different threads.) I guess it's time to stop blabbering, let's get started.
Why does ZUN wants to create Touhou?
You might laugh at this one, but it's a quite interesting topic. Most people will just say :"Well, aren't ZUN just doing it for fun?" That's one possible theory. But, however, I have another theory.
Touhou is a franchise created by ZUN, under the request of Yukari, to help spread faith and belief of Youkai and God.
This one actually have many points that back it up. The most prominent being the Great Hakurei Barrier and the Boundary of Dream and Reality, which is the two barrier that protects Gensokyo from human invasion. Those barriers are not physical, as shown by Marisa. So, in order to keep the barrier going, some kind of spiritual energy is required to power it (Spiritual energy does actually exist). Yukari certainly doesn't have enough energy for powering those barriers on a long-term basis (Which is probably why, Yukari is sleeping all the time). So what is the best way to gather those energy? Of course, from the Outside World! Yukari found ZUN when she was travelling to the outside world, and they quickly became good friends. Since ZUN is also quite interested in those ancient Japanese mythology (Which some of them are lost since Meiji Restoration, where the legends about Youkai are gradually forgotten and the Barrier was bulit to protect the Youkai and God who lost faith from disappearing), Yukari then requested ZUN to make a game that represents the events happening at Gensokyo (Like the Incidents, and how Reimu went to solve them), which ZUN then happily accepts, since making game is quite fun for him.
You might ask here:" Why don't Yukari just make it an Anime or Manga? Aren't them more popular?" And I can tell you here, the answer is No. Well, not entirely. Anime and Manga did goes quite viral for a while, but following the popularity burst, the popularity can also die down pretty fast (For long-running series like One Piece and Naruto, their popularity will also eventually decrease when the series is finished). But for games, it's almost impossible for people to forget about them once they gained fame. Look at Pokemon, Mario and Zelda. Those are ANCIENT games from the last century, and is still very popular nowadays. Also, at the end of 20 century, shooting games are still quite popular, and ZUN(or Yukari) managed to catch the trend. Which is why, Touhou gained a lot of popularity when it cames out. (Now, hopefully you gets a good reason why Yukari choose to make Touhou a game!)
This also perfectly explains why even after Touhou became very famous all over the world, ZUN still doesn't want to commercialise the games (Like, selling them to a big company for mountains of crates of beer). Because what ZUN really wants is not money, but rather, helping his best friend Yukari Yakumo and the land she loved, Gensokyo.
But what if , ZUN really just created it for fun?
Well, if that's the case, then it is quite easy to explain as well. According to my research (So far), anything that you draw and any story you write becomes real.
WARNING! HEAVY SCIENCE THEORY AHEAD!
This might sounds horrifying, but don't worry, they are just in a different dimensional world than us. Like, when you draw a stick man on a paper, the stick man is considered "Exist". But it won't just pop into your room, screaming for attention at a random day, since it exists in a different world than us, a world with the only definition of "Length" and "Width", which is considered as a 2D world (Our world is 4D, with "Length" Width" "Height" and "Time"). If you erased the stick man, the stick man ceased to exist, but it still exists in the Timeline of that particular dimension (Which, the Timeline is somehow based on our dimension). Now, let's get back onto track. Certainly, as ZUN continues to add more settings to the "characters", their dimension begins to expand (When you add more settings to the background of the characters, the definition of "Height" or even "Time" is added, since we create them based on our experience in this 4D world). And when he creates Yukari, the whole world will just go upside down, if she feels like it.
But if they are the character you created, you can just control them by changing their personality and such. Is that right? Well, it is, as long as you don't give them any dangerous power. Which, in this case, is Yukari and Keine.
As we all know, Yukari-sama's power is the control over boundaries. The boundary can be anything, such as the boundary of existence, life and death, race, gender, EVERYTHING.(Althought I might be terribly wrong, a dimension without boundary is considered to be 10D, according to Stephen Hawkings). This power, along with many setting ZUN added to her, allows her to break free from the Author's Chain (Funny name I gave to the concept I listed above), and possibly allowing her to break the others free from the Chain as well. Which means, she can also cross the boundary of parallel world to visit us. Really, I'm serious. you could very possibly find Yukari ripping open a gap on your wall, looking at you at ANY moment (If she is interested in you). And also, she can get into anyone's computer, or even the internet, to look at some funny posts about people saying that she is an old hag (Luckily, as far as I know, she don't care!). There is a great chance that she came MotK at least once, and it is even possible that she is looking at our threads now!
Whew, yeah! No more Science!
If that's the case, then we are still very lucky. Her laziness, smartness and love for Gensokyo means that she is too smart to do silly things that mess up our world.(also, she is possibly too lazy to do that as well!) But the good thing is, there is 99% chance that she also created a Gensokyo in our world, a REAL one!
Conclusion: Following both theories, we can pretty much say that GENSOKYO IS REAL! unless there is someone even smarter than me can disprove my theories, which is something I look forward to.
Oh yeah, finally finished, my finger are all sore from typing this! Hopefully I got your brains big like watermelons! Let me know if you got any questions and comments!
But hey, it's just a theory, A GAME THEORY! (Obvious reference!)
