Selkie has an innocent and cheerful personality, one that has never seen danger. She is very active and almost never stands still due to the fact that she loves to play with others, especially her father. Fun-loving, carefree, and playful to a fault, Selkie often focuses on playing and having fun, rather than danger, sometimes with her game being the cause of the danger. She ignores advice (for games to play) if she sees them as boring and either suggests a new one or continues with the one she's currently doing, as seen in supports with her mother and Shigure. She can be a little dense in life-threatening situations as she consistently considers fighting as a game. However, like her father, she always feels the need to repay a favor done for her.
