Those who receive the Revelation of Babel must overcome many battles and trials. By grasping the hand of their special partner, these "Hand Shakers" transport themselves to the realm of Ziggurat, an alternate dimension where time no longer exists. Each pair of Hand Shakers must battle it out for the right to meet with God, who will reward them by granting them a single wish. Tazuna Takatsuki, a high school student with a penchant for fixing things, is one of these Hand Shakers. After receiving a request for repairs from Professor Makihara of a nearby university, Tazuna stumbles upon Koyori Akutagawa, a bedridden girl that reminds him of his deceased sister Musubu. Remembering her dying wish to never let go of her hand, Tazuna grasps Koyori's hand and awakens his power as a Hand Shaker. However, Koyori's life is directly tied to her status as a Hand Shaker, meaning if Tazuna was to ever let go of her hand she would die. With meeting God being their only hope for saving her, the duo must find a way to make their unique powers mesh together, overcome the opposing Hand Shakers, and make their wish come true.

Recap of episodes 1-6 with new narrations.

On a hot summer day, five university students sneak into the library storage to look for some treasure. They find two sets of female antique mummies from Italy around the age of 14–20 years old.

One of the students, Sayaka, rips open the mummy and takes out a stone called "stone of life," which gave the mummies super strength and eternal life. Having stolen their "stone of life," the two mummy girls wake up and become zombies after 100 years in order to get it back in a bloody gruesome way, smashing their heads and eating their flesh for power.

The only way for the students to get out is to somehow find a way to kill the zombie girls. Will they be able to survive?
