Bonus segments of Cinderella Girls Gekijou 3rd Season streamed on The iDOLM@STER Cinderella Girls Mobage following the television broadcast.

Episodes 1-3 focus on Dera welcoming ladies to his bar. Episodes 4-6 focus on Choi-chan.

The stage is the close of the Edo period, an age when, not unlike our own time, both natural and man-made disasters left chaos in their wake. Manjiro makes a living helping the people of the troubled capital city, but behind the scenes, he also works in secret to take back precious belongings stolen from the people by unjust political powers and conspiratorial menaces. The people call him "Get-backer Roman."

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?
