Does She Still Like Robots?
As Mitsuhiko begins streaming the encounter via Iru-O, Kimijima reveals that on the day of the S.S. Anenome incident he had been planning on using the passengers as test subjects for a radiation experiment but was murdered by Misaki to save Kaito and Akiho when she caught onto his plans. Afterwards, Kimijima began appearing to her through the Iru-O network, threatening to reveal what she did along with Kaito and Akiho, forcing her to cooperate with his plan. Kimijima further states that he had threatened Airi in a similar manner and if it wasn't for Misaki's meddling, Project Atum would have occurred in 2015. Akiho questions Kimijima on whether Misaki still loves robots and he suggests that she still might, since she didn't stop playing Kill-Ballad. Akiho further vows that they will stop Kimijima and his plans using their giant robot and save Misaki whilst Sumio helps disarm Airi, who faints while Kimijima disappears.
