S1, E2: Hakuro and Kaede are waiting to meet Makio Yagami, but find him collapsed at the bottom of an escalator. While the paramedics apply first aid, Hakuro and Kaede rush to the Yagami home. Kaede thinks someone from the Yagami family pushed Makio to stop him from leaking information regarding the inheritance. That means anyone who was away from the mansion at the time is a potential suspect. Having only just returned, the family butler also becomes a suspect. However, Kaede is suspected too, since Makio's phone shows that she called him just before his fall. Hakuro defends Kaede but wonders how can she calmly continue her pursual of the culprit without being shaken by Makio's fall. That's when Yuma asks Hakuro to steal Kaede's smartphone, in order to check whether she is Akito's wife.
