Story Summary
ABIS HQ, Interrogation Room, Monday
Date interrogated Ota about the incident at the cold storage warehouse. Date asked Ota if Mayumi was at the warehouse, due to her fingerprints on the Odoroki-man Chocolate and the floral knife the culprit used. Ota insisted that his mother could not be the killer, but he did discuss the possibility that she might have hired someone to kill Iris Sagan. Date assured Ota that it was unlikely Mayumi could be the killer, since she was shopping while the van drove off. However, he still needed to talk to her to learn the truth of the incident.
Matsushita Diner, Monday 10:11 PM
Date saw Mayumi as soon as he entered the diner. She told him that she remembered everything about the warehouse, and confessed to the crime.
