Ep. 5: Kaito investigates a mysterious girl while uncovering a hidden report about solar catastrophe
Aired on November 9, 2012

Kaito learns from Junna about sightings of a mysterious girl, while Akiho and Subaru prepare for a Robo-One interview. Kaito and Junna visit the beach, where they find a beached whale, and he suggests she join the Robotics Club after leaving karate. That night, Kaito follows a strange voice to an abandoned building and meets Airi, an Iru-O app that has tried to contact him for 8 years. Airi shows him Kimijima's Report No. 1, written out of fear for his life. The document claims NASA discovered monopoles at the Sun's south pole in 2000 and covered it up. It predicts solar flares in 2012, 2015, and 2019, leading to an explosion in 2020. As Kaito questions the accuracy of these predictions, Mizuka reacts strangely when he mentions Kimijima.
