Ep. 7: Hondomachi investigates Narihisago and Kiki Asukai while Momoki is framed for John Walker

The forensic team collects cognition particles from the Challenger and Narihisago. Hondomachi enters Narihisago's id well to check for contact with John Walker. He finds no link to Walker but discovers an active Mizuhanome cockpit connected to Kiki Asukai, the Challenger's last victim. Momoki admits he saved Kiki but has not seen her since the investigation. Hondomachi dives into Kiki's id well while still in Narihisago's. The team is interrupted by an arrest warrant for Momoki, who is framed as John Walker. Police found decayed remains of the Mizuhanome inventor in Momoki's yard. They also traced mics and cameras in serial killers' homes to Momoki's computer. Narihisago is furious and asks Togo for permission to dive into Momoki's id well to clear his friend's name.
