The Spread Shot of Youmu Konpaku from the world shrouded in scarlet mist. She unleashes waves of energy from her sword. Phosphorous is an element that can supposedly be extracted from corpses. It's combustible, highly reactive, and can be used to make various medicinal products. There's also a theory that phosphorus is a type of incredibly pure and dense temperament, leading some people to think that phantoms are made out of it. Youmu doesn't know anything about that, but she does know that expelling phosphorus while swinging her sword produces a pretty explosive attack.

The Focus Shot of Youmu Konpaku from the world shrouded in scarlet mist. She slashes down onto her target. Perhaps Youmu uses this technique to prune tall trees. That would make sense because, like her grandfather Youki Konpaku before her, she is both Hakugyokurou's fencing instructor and gardener. Her gardening work provides plenty of opportunities to practice her sword skills. The wise Yuyuko must have thought of this when she made Youmu her gardener.

A Spell Card of Youmu Konpaku from the world shrouded in scarlet mist (a Touhou LW original). She attacks with the red Yama's wrath. After the scarlet mist covered Gensokyo and seeped into the Netherworld, it continued to expand all the way to Hell. While the Yama's face is usually depicted as angry and red, this has surely made it even redder. The Yama couldn't possibly let this slide.

A Spell Card of Youmu Konpaku from the world shrouded in scarlet mist (a Touhou LW original). This attack isn't about being two-faced or disingenuous but about the Buddhist doctrine of two truths. A difference of perspectives separates humans from gods and Buddha. This creates a duality of truth where humans can only understand an incomplete Conventional Truth formed through their own observations of the world, not the Ultimate Truth, which is only understood by enlightened beings. This concept can also be applied to people of different stations who have inherently different perceptions, such as an employer and an employee.

The Last Word of Youmu Konpaku from the world shrouded in scarlet mist (a Touhou LW original). Feeling the need for a new weapon to use in battle, Youmu prepared this attack. But she never expected to use it so soon. Yuyuko told Youmu about Gensokyo and the mansion releasing the scarlet mist... in the form of a scary story. Contrary to Yuyuko's intentions, the ever-impressionable Youmu became terrified of Gensokyo and concluded that she must exterminate all the spooks and monsters there with her blade, Hakurouken. Yuyuko couldn't decide whether this was an act of bravery or cowardice, but there was someone else who appreciated Youmu's ardor... the Yama in Hell. She also wished to know what was happening in Gensokyo. However, she would prefer it if Youmu showed more restraint with Hakurouken.
