Wakasagihime

Wakasagihime is a normally quiet, peaceful youkai mermaid who lives in the Misty Lake, singing songs and picking up stones. However, thanks to the Miracle Mallet's power, she became ferocious; after the incident was resolved, she went back to being her normal self. Perhaps as a direct result of being a mermaid, she benefits from increased power while underwater. Apparently she either keeps a low profile or everyone nearby just ignores her, as all playable characters in Double Dealing Character are quite surprised to see her there. Kagerou Imaizumi is surprised to hear of her attacking people, claiming that she is usually so timid that she wouldn't even kill a bug. She is a member of the grassroots youkai network.
