The Deathbusters have captured someone from the Sailor Guardians team and replaced them with a Daimon imposter! Fortunately, Luna and Artemis discovered their evil plot and now everyone must work together to identify the pretender. By asking the characters a series of questions and then comparing the answers for ones that don't align with the rest of the group, the cats can unmask the imposter and direct the rescue of the captured teammate before it's too late.
