A nerd must fight powerful spirits and aliens all vying for the secret power of his “family jewel,” so who better to fight alongside him than his high school crush and a spirit granny?!
Momo Ayase and Okarun are on opposite sides of the paranormal spectrum regarding what they’ll believe in and what they won’t. Their quest to prove each other wrong leads them down a path of secret crushes and paranormal battles they’ll have to participate in to believe!
Momo struggles to counter a sudden attack by alien clones, but through a temporary truce with her sworn enemy, the alien Serpo, she is able to persevere. However, her troubles are far from over—it’s now after 10 p.m.! In order to avoid the slit-mouthed woman Reiko Kashima, who is still very much on the hunt for her, Momo and Serpo must hide out overnight in a manga cafe. And when Momo finally returns home in the morning, she finds her friends are gravely injured and being treated by none other than Mr. Shrimp!
