About this game
Wakasagihime is a usually withdrawn freshwater mermaid who enjoys collecting rocks and singing songs.
Under the influence of the hidden treasure, the Miracle Mallet, she became aggressive and attacked any passers-by. She was quickly subdued and the incident was resolved. This, however, gave her a taste for a life she had otherwise not sought after and motivated her to be more outgoing and break out of her shell.
This is a puzzle exploration adventure game set in the depths of Misty Lake in Gensokyo.
