Yukari is, as she created Gensokyo.

Youkai and Gensokyo never originally existed in reality. Maribel Hearn, having the ability to see "boundaries" was able to see the boundaries between fantasy and reality. Having an interest in Japanese folktales, as did Lafcadio Hearn, she brought a fantasy land into being and populated it with mystical creatures for her own desires. This is why everytime a new magical creature is brought into Gensokyo from the "outside world" it is done so by Yukari. She also edits Akyuu's writings so that things in Gensokyo will seem as she sees fit.

How Maribel did this is probably related to the fact that her powers seem to be growing in the stand-alone music CDs. This would somehow be in combination with Renko's vast knowledge of physics, as Yukari is a master mathematician and probably utilizes her math skills to use her gap powers in the first place. They also live in the future, so future magics.
