After learning his father, the infamous Kaitou Kid, was killed over the mythical Pandora Gem, high schooler Kaito Kuroba takes up the mantle to find and destroy it before a shady organization can obtain its immortality-granting powers.

Kaito Kuroba, a normal teenage high school student, stumbles across the secret of his father's death: his father was not only a magician, but the famous phantom thief Kaitou Kid, and was killed by an organization for reasons unknown. Taking up his father's mantle in an attempt to bait the killers, Kaito performs a number of thefts and eventually learns that his father died for interfering in the organization's quest to find the Pandora Gem. Pandora is said to glow in the light of the moon, and beneath the moon and a certain comet, will shed a tear granting immortality to whomever drinks it. Kaito then decides to search for Pandora as Kaitou Kid and destroy it, in order to prevent the organization from obtaining their goals.—Detective Ham
