Asabare (a Touhou LW original) refers to a clear sky in the morning. This is an apt temperament for Yamame since it is said that there will be clear skies all day if you see a spider in the morning. Yamame is endowed with Earth Phase, as a tsuchigumo, and Star Essence, as one of the people who did not obey the Imperial Court of Japan. The encompassing and regenerative Earth Phase resists Fire Phase, because fire produces earth, but it is weak to Wood Phase, because wood parts earth. The diverse and uncooperative Star Essence resists the cooperative and indecisive Moon Essence, but it is weak to the charming and arrogant Sun Essence.

The ability of Yamame Kurodani as a tsuchigumo. This is a particularly nasty ability even for a youkai of the Underworld, who are generally hated by others. However, she does not seem to want to use this ability carelessly. Tsuchigumo are probably best known for the story about how one made a famous youkai exterminator warlord sick with a fever. Long ago, in both the West and East, it was believed that diseases were caused by "bad air," called miasma, which was a product of foul water. Sanitation, flood control, and urban developments such as water supply and sewage system improvements may have also been an act of youkai extermination. On the other hand, there is a theory that tsuchigumo may have been the name for tribes or clans of people who did not show allegiance to the Imperial Court of Japan. Some studies even seem to regard them, and other youkai, as the remnants of fallen ancient gods. However, even if one tries to understand the origins of youkai, the rumors about them will always be horrifying. Regardless of how they came to be, diseases are frightening, and unknown hostile forces are a threat. Yamame lives deep underground in Gensokyo with her terrifying ability.
