En-u (a Touhou LW original) refers to rain so fine that it appears to form a thin mist. "Who and what I am is limited by my perceptions of the boundaries between outer space and inner space, macrocosm and microcosm. I believe that others are bound by similar limits. However, this might not be the case. Who's to say that there aren't other types of consciousness that are just as valid? That's what it says in this book: Magical Principles of the Star System Worldview." "Rain, forests, and magic..." (Strong against Water Phase, Wood Phase, and Moon Essence.) "Sounds like a description of the Forest of Magic. This whole world, this whole planet, is the Forest of Magic. Or maybe... this world is me."

The ability of Marisa Kirisame (F1) from Multiverse Trail 4 (a Touhou LW original). It's basically the same as the abilities belonging to most other Marisas. This divergent fate doesn't seem possible. Something must have gone wrong when Marisa was traveling between parallel worlds, causing her to crash-land on this mysterious planet... It's as if the Forest of Magic texture has been copy-pasted everywhere. There's no sea or mountains, only a never-ending forest covered in a suffocating blanket of miasma and spores. Marisa isn't sure when it happened, but she has lost the will or desire to escape. This forest has a thirst for knowledge that seems to echo Marisa's. To the forest, she is a marebito, a wellspring of knowledge from another world. The following is a report found in a book that outwardly resembled a grimoire. It has been rendered barely legible by the fungus growing all over it. Marisa stopped counting the days. She doesn't know when exactly, but it was a long time ago. Her sense of self was slipping away. Soon, it would completely fade. Miss Retroid was lying beside her in a similar state. What went wrong? Was it because she licked those mushrooms? No... "It's 'cause of magic. That's what it all boils down to." If you talk to a mushroom, it won't talk back. Everyone knows that. But Marisa had questions that only a mushroom could answer. She wanted to know what they were, what they were doing, what their purpose was. Of course, they couldn't tell her, so she did what any good magician would do and started researching. Essentially, she tried to draw the answers out of them by boiling them, straining their juices, and adding whatever she could think of to the solution. While unintelligible to most, these experiments were a direct, purely distilled conversation. That's what research is―a conversation with things that cannot talk back. "In the end, I don't know who won. Was it me or the mushrooms?" Research is a conversation, but that doesn't necessarily mean it gives you the right answers. After all, sometimes there is no right answer. Searching for something that doesn't exist is a wasted effort. Unfortunately, you can never know when something doesn't exist, so you end up pouring infinite time into a futile search. Mushrooms might not have a will of their own. And while it looks like they can move, perhaps they are merely swaying in the wind. Or maybe... that's what they think of Marisa. This is the kind of thing that she assumed would be a problem with aliens. She didn't even struggle this much when dealing with youkai, though, admittedly, her memories of youkai are hazy. Conversing with true aliens, from far-off planets, would at least feel unreal and exciting, whereas mushrooms... It's like they're too close, too familiar. "Still, we've been through a lot together, huh? So many memories." For a second, she thought a mushroom spoke to her. But she soon realized it was her mind playing tricks. Mushrooms wouldn't talk like that. Surely this was just some kind of vision she was seeing before the end. It felt like this was her Omega Point, as if her life were constantly flashing before her eyes. The Omega Point... Infinity... Did this mean that as long as she stayed like this, she'd never die, that time would never progress? This would also mean that the clock frequency of her thoughts would keep slowing down... She was already bored. She was sick of this. "Then why don't we play together? Like old times." The mushroom was starting to get on Marisa's nerves. Why in the world would she want to play with it? Sure, she wanted to play with mushrooms before. That's why she'd been trying to converse with them all this time, but wasn't it a bit late for that now? And why was it talking so normally? It's a mushroom for goodness' sake! This didn't make any sense. It stopped talking, which only infuriated Marisa further. Her body and mind were becoming one with the forest, with the fungi. She no longer knew where she ended and the forest began. The same thing was happening to Miss Retroid lying beside her... "Yes, I'm also becoming one with the forest. That's why we can play together again." [The report ends here.] Tiny Miss Retroid Presumably, this special type of Satellite, called a Foundling, shrank for the same reasons as Marisa. She's Marisa's experimental familiar and her friend. Even though she cannot talk, she is clearly stressed out by this whole situation, even more so than Marisa. And, of course, she has also been infected and degraded by the fungi.
