Ryoua (a Touhou LW original) refers to nights when the Moon shines brightly, particularly the night of the Harvest Moon. Mamizou is endowed with Earth Phase as the leader of the youkai tanuki. The encompassing and regenerative Earth Phase resists Fire Phase, because fire produces earth, but it is weak to Wood Phase, because wood parts earth. She also pretends to be an alien in an attempt to safeguard Gensokyo's future. (Strong against Earth Phase.)

The ability of Mamizou Futatsuiwa from the world where secrets constantly get revealed (a Touhou LW original). This ability doesn't seem any different from the Mamizou of our world's ability. The 14.5th Prolonged Incident. All the information pertaining to the prolonged version of what was later known as the Urban Legend Incident is false data. Mamizou was worried. The Occult Ball Nue found was different from the ones brought to Gensokyo by Sumireko. Without their particular abilities, they might not have seen through the deception. Then again, Mamizou was living in the outside world until only recently, so perhaps she sensed that one of them didn't come from there. Also, considering how she transformed one of her tanuki underlings into "Gensokyo's Occult Ball," she is probably more alert to the deceptions of others. Or perhaps all of this speculation is wrong, and she only noticed because the extra Occult Ball from the Lunar Capital was imbued with alien occult power. It was all a Moon hoax. According to secondary true data, there was a war between the humans who landed on the Moon and the Lunar Capital. However, there are significant doubts about whether this actually happened since the only record of this event is from the Lunar Capital's perspective, specifically the contents of a telepathic message sent down to Reisen Udongein Inaba in Gensokyo. That said, there are other reports of Lunarians being amazed by the advanced technology of Earthlings, so it's probably safe to assume they at least saw them as a threat. If that's the case, then Earthlings (i.e., ordinary humans) may have detected some trace of the Lunar Capital. It's unlikely, but perhaps they even witnessed a moon rabbit pounding mochi. This would mean that the conspiracy theory about the government hiding the fact that astronauts made contact with aliens on the Moon is actually true. This conspiracy was a big part of the Lunar Capital's plan to invade Gensokyo because if that urban legend spread and materialized, the Lunar Capital would relocate there. For some reason, this Mamizou has vast reserves of occult power. Perhaps it's because the life she led in Sado, masquerading as a human, was incredibly similar to the idea of extraterrestrial beings hiding among humans on Earth, but nobody knows for sure, not even Mamizou. However, that won't stop her from using it. A real alien civilization, the Lunar Capital, could invade at any time, and to have any chance of stopping them, she'll have to use all the resources available to her. Back when Mamizou was investigating Gensokyo, she came across two theories: the Detached Gensokyo Theory and the Patchwork Theory. Gensokyo does not exist in any one specific place on Earth, and in the outside world, the location of Gensokyo is a complete mystery. If you try to leave Gensokyo, you will end up back where you started without encountering any kind of visible boundary. According to the Gensokyo Chronicle, this is due to the barrier surrounding it. However, the chronicle also states that Gensokyo is surrounded by mountains, which seems to directly contradict Mamizou's own experience. When Mamizou peered through a gap in the barrier at Hakurei Shrine, she saw the night sky and a modern-day city. This led her to the conclusion that both theories are correct. In other words, Gensokyo is a collection of patched-together regions that used to exist independently but now reside in the same space, detached from the outside world. That would explain how Gensokyo can be right next to mountains and a city. Mamizou came up with a plan. She would use Gensokyo's patchwork nature to take a part of its systems and turn Sado into an Otherworld. Mamizou and Nue would manage it, and Sumireko would act as its modern-day shrine maiden, holding it all together. When the Lunar Capital invades Gensokyo, they will hole up in Sado to weather the storm. However, this plan was far from foolproof, and it wouldn't provide any long-term solution. Mamizou, more than anyone, wished there was a better way.
