Ep. 7: Hondomachi menyelidiki Narihisago dan Kiki Asukai sementara Momoki dituduh atas nama John Walker

The forensic team gathers cognition particles from the Challenger and Narihisago, with Hondomachi diving into Narihisago's id well to discover if he had contact with John Walker. Although Walker is not found, Hondomachi stumbles upon an active Mizuhanome cockpit linked to Kiki Asukai, the last victim of the Challenger. Momoki discloses that he saved Kiki, but has not seen her since the Challenger investigation. Before she can be extracted, Hondomachi dives into Kiki's id well while still in Narihisago's well. The investigation team is waylaid by an arrest warrant for Momoki, who has been framed as John Walker. The police found the decayed remains of the Mizuhanome inventor in Momoki's yard, and found that the mics and cameras in the homes of serial killers all linked back to Momoki's computer. Narihisago is irate upon hearing these accusations, and begs Togo to allow him to dive into Momoki's id well to clear his friend's name. (Source: Wikipedia)
