Summary[]
Yesterday, while walking at night, Aira is hit in the head by a golden ball and gazes at a stream of light riding along the railway, which prompts her to take possession of the golden ball after becoming amazed at the sight. Back in the present at school, Aira is met by her friends who brings over the requested items she asked for in preparation for her mission to save the world. Aira then warns her friends that she has spotted a mysterious woman in red outside the school, only to hear from them that the woman is only visible to her and comes to the conclusion that she must be Momo's familiar who was sent to spy on them. After trying to hide from the woman, Aira is caught acting suspicious by two boys and tries to play it dumb while secretly communicating to her friends to meet her after school. Meanwhile on top of the roof, Momo and Okarun learn from the Turbo Granny that she spotted a mysterious woman lurking around and discuss the possibility of a human picking up one of Okarun's golden balls, which could lead them to awaken the power to see spirits and be attacked by them. The Turbo Granny then tells the two that she will explain more about the mysterious woman after school. Later, Aira wonders to herself if she could handle fighting both Momo and her familiar and looks outside to see the woman in red getting close. While in the halls, Momo is requested by Aira, who she recognizes as the girl she dropped the basin on yesterday, to meet with her in private. Momo agrees to talk to her somewhere else, since she did not want to make things difficult, and tells Okarun that she will meet up with him later. Okarun is then informed by the Turbo Granny in his backpack that the mysterious woman she spotted earlier appeared. After following Aira to an abandoned building, Momo finds herself jumped by Aira's two friends who handcuff and restrain her while Aira tries to exorcise Momo with a rosary and a bible. Becoming irritated with their actions, Momo uses her psychic powers to push Aira's friends off of her. Aira becomes shocked to once again see Momo's "demon wings" and pulls out the golden ball to aid with her exorcism attempt. After learning that Aira has one of Okarun's golden balls, Momo tries to explain to her as to what the ball is but has no luck getting through to her. She then sees Okarun running in worrying about her and warns him that Aira has one of his balls and that she is the mysterious woman. However, Okarun corrects Momo, explaining that Aira is the mysterious woman's target who suddenly appears to grab the girl off of Momo.
