Mikazuki (a Touhou LW original) refers to the moon on the third night of the lunar calendar, as well as the phase of the new moon before it waxes half full. The crescent moon is an apt temperament for Yorihime's astute and dignified personality. Yorihime is endowed with Wood Phase, with her flexible spiritual nature that allows her to house various gods, and Moon Essence, which is calm and collected. The strong and kind Wood Phase resists Water Phase, because water nourishes wood, but it is weak to Metal Phase, because metal carves wood. The cooperative and indecisive Moon Essence resists the alluring and arrogant Sun Essence, but it is weak to the diverse and uncooperative Star Essence.

Watatsuki no Yorihime's ability allows her to summon divine spirits and house them within her body. Considering the fact that she summoned the ruler of the Yaoyorozu no Kami, Amaterasu, the goddess of the sun, there may not be any gods that she cannot summon. However, it is unknown what would happen if she tried to summon Kanako in Gensokyo, her superior Lord Tsukuyomi, or Hecatia Lapislazuli. It is also unknown whether she can summon just a portion of their power or not. Regardless, her ability is undeniably powerful. According to Yorihime herself, the number of different Yaoyorozu no Kami she can summon is eight million. (Yaoyorozu means both eight million and countless in Japanese.)
