Episode Description:
Natsumi and Miyuki travel to a shopping mall in order to go shopping for apparel. Gossips and rumors began to flourish within the mall, concerned of a possible bomb threat. The customers and employees are advised to evacuate the mall, however Natsumi and Miyuki are uninformed. Tokuno briefs them about the bomb threat. The bomber contacts the mall, creating a game of riddles. Natsumi and Miyuki fray to find the first clue, known as Rico. Everyone eventually figures out that Rico is a former doll that appears on the clock tower. They find the bomb attached to Rico, supposedly able to diffuse it. After another call from the bomber, hinting of a massive bomb, Natsumi, Miyuki, and even Tokuno manage to find his whereabouts and catch him. After interrogating him, they soon realize that the new bomb is planted in the middle of the clock tower dolls. Natsumi and Miyuki race to the roof, where they are to pry open the clock face from the outside in order to get to the bomb. When the hour is struck, Natsumi strains to prevent the other dolls from setting off the bomb, while Miyuki attempt to successfully diffuse it.
