Dyson Tree (a Touhou LW original) refers to a hypothetical genetically engineered plant capable of growing inside a comet and producing a breathable atmosphere. This is an apt temperament for this world's Yuuka, who creates kaiju. This temperament resists the Capital (Moon Essence) and the rebels (Earth Phase).

The ability of Yuuka Kazami, the kaiju professor (a Touhou LW original). This ability is significantly different from our world's Yuuka. Not much is currently known about this Yuuka's world, but one can assume it's filled with kaiju. However, it seems that her "kaiju" aren't the same as the kaiju that the sagacious spirit speaks of... Depending on the topic, Yuuka can be quite a talkative professor, but she rarely speaks about herself. She herself was the first kaiju she ever created, and at some point, she had a strong connection to the Capital―that's all she's willing to share. Anything else known about her comes from strewn-together fragments of rumors and is far from certain. Yuuka's area of research is often said to be the study of "cells," but those who claim so are exclusively people other than Yuuka, which is a phenomenon common in the world of research. The most minute building blocks of life are cells, but Yuuka claims that, in fact, memories and abilities take that title. Memories and abilities exert influence on and are nestled within one another. That definition may seem confusing, but those are Yuuka's exact words on the topic. It follows then, that memories and abilities must always be discussed in parallel, but due to the difficulty of doing so, they are often jointly referred to as "cells," which distresses Yuuka greatly. She asks that people at least use the term "seeds." The influence that memories and abilities exert on each other is incalculable, but it seems they can be likened to plant seeds based on the extraordinary growth they demonstrate. Yuuka's current research involves separating and extracting a being's memories and abilities, the foundations of existence, and implanting them into another. In doing so, she seeks to disprove her own theory. Her research was what gave rise to the new youkai, the kaiju. There are many old stories about kaiju. They came into existence long ago in the outside world as beings to be feared. On many occasions in the past, kaiju were pointed to as the cause of epochal disasters, including those caused by humans, and were symbols of great fear. But, as time went by, they came to be viewed in a more heroic light… or so it's said. The truth, however, is that kaiju only ever existed within emakimono, plays, and fairy tales. They were nothing more than make-believe creatures. In many ways, kaiju are similar to youkai. To humans, the youkai of old could also be considered make-believe creatures. To Yuuka, the issue was no longer limited to just kaiju, and so, naturally, she began asking herself what the youkai were, and when no answer could be found, she fell into the pits of depression. Were they not apex beings that attacked, abducted, and ate humans? With the truth hidden from her, Yuuka had no choice but to hypothesize the existence of a certain place. One she had only heard rumors of... One that had been scrubbed from her memory beyond recollection... Gensokyo. Could that be a safe haven for youkai? What then appeared to her was the end of a thread, like spider's silk. It connected to what would come to be known as the multi-dimensional neural network. Fate, it seems, is always uncertain and unpredictable, and never allows you to choose for yourself. Yuuka reached out and grabbed the white thread. She saw a world that had already been lost, and a version of herself living inside.
