The gang take Ika, who had never heard of ghosts before, on a test of courage at the local cemetery, but she just ends up scaring everyone with her ability to emit light. Later, Ika becomes frightened when inflatable killer whales start showing up around the place (believing they are real), since killer whales are her natural predator. When Takeru asks Gorō to teach him how to swim, Ika tries to teach him to avoid the whales. Later, a new girl, Nagisa Saitō, joins the stand, though is a bit nervous around Ika, who becomes pleased that someone actually fears her.
