For some reason, she seems to be plotting to dominate her seniors. What could have brought about this change in her state of mind?
~ Profile

Wakasagihime is a mermaid that lives in the Misty Lake and one of the youkai that became stronger because of the side-effects of the Lucky Mallet. She is the first boss of Touhou: Double Dealing Character and, much like other bosses, became a recurring character after that. She is usually not an enemy of humans, but thanks to her newfound power she planned to join the Youkai Rebellion and rebel against her superiors. Her ability is to become stronger when in water.


She has dark blue hair and eyes, as well as small fins in the place of ears. She wears a frilly green leaf-patterned kimono which fades to teal at the bottom. In the place of legs, she has a blue-grey fish tail ending in two large fins.



  • She is one of the characters without legs. The other being Soga no Tojiko, Unzan, Kisume(?), Konngara and Mima in her official artwork/portrait.
  • Wakasagi is a kind of Japanese fish native to the lakes and estuaries of Hokkaido, Japan and Hime (姫) is the Japanese word for Princess.
  • Thanks to being half-fish, one of Marisa's dialogue and that one incident with Kagerou nearly eating her, most fanart of her depicts her as being preyed on by the rest of the cast.
  • Some fans believe that she may have been inspired by the blue-haired mermaid Megumi Yaobi from the fan-made Touhou game Marine Benefit, although unlike Wakasagihime, Megumi has an actual pair of legs.
  • Fans depict Wakasagihime and Kagerou to have a girlfriend and girlfriend relationship, sometimes when Kagerou tries to ask Wakasagihime in fanart she will freak out.
