The Demon Convenience Store in Beika Town

A new convenience store has opened in District 3 of Beika Town. Its sign has a black background with red lettering, and its name is "Devil's Convenience Store."

The owner, Baize, doesn't sell ordinary products. Instead, he sells Devil Cards, each of which can draw an extraordinary item. Wind God Leg, the Badge of Truth, the Guardian Feather, the Boundary Ring, the Black Gate Key... Every card draw is like tossing a bomb into Beika Town's murky waters.

Ran Mouri draws a martial arts manual, Sonoko Suzuki gets a lifesaving talisman, Conan Edogawa obtains a magnifying glass that enlarges clues, and Eri Kisaki unexpectedly becomes a key temporary customer of Devil's Convenience Store.

What should have been nothing more than a card-drawing game in a strange shop gradually leads to a series of dangerous experiments with the arrival of the mysterious "V": parasitic needles, duplication mirrors, the White Gate, the Number Zero Mother Needle, and more. The White Gate can duplicate people, cut away failed lives, and even alter a person's very existence.

To protect Ran, uncover the secret behind Conan, and stop V from opening a second hidden Main Gate beneath Beika Town, Baize and Eri Kisaki are forced to form a temporary alliance.
