[Machine Translation] The eerie black hole that appeared in the Reigumi is getting bigger and bigger. At this rate, in a few days, the Reigumi, North School Building, Asahi Elementary School, and N City will be swallowed up! In order to seal the hole, the past Kowaiimono Kakusha - Yoshino, Haru, Yuka, Reiko, Yuka, and Akari - have gathered together. They are truly the strongest all-stars! With one talisman for each of them, the ritual went smoothly... But, as expected, there was a problem! But we are not giving up yet. Because that's why they are the "Scary Things Section"! From elementary school intermediate level.
