Invaders of the Rokujouma!? Collector's Edition #7

Plot

Contains Volumes 18-20!

Yurika comes to everyone with an unusually serious request-she wants them to help her savior and mentor, Nana. Meanwhile, children start going missing in Kisshouharukaze City. All signs point to one cause: Darkness Rainbow is back in town.

Yurika has made the bold decision to attack Darkness Rainbow's base in order to prevent all-out war in Folsaria. Koutarou and the girls will have to consolidate all the power they have-and help from some new(?) allies-to get home safely this time.

In a collection of side stories, Yurika quits cosplay(?), Sanae and Ruth go dream diving, and Maki confronts Theia about some unexplained expenses. Then everyone participates in the school cook-off, and the results are explosive to say the least.
