An Order of Wine With a Side of Crime

At 9:30 P.M. an unidentified person is seen entering the apartment of bank CEO, Orlando Murluto. An hour later he is lying on the floor dead. His body is found in the morning by his valet, there to make his breakfast. No prints, no description, no nothing, except a lone cup lying next to the victim's body. Most police rule it as a suicide due to inadequate evidence. Now it is Police Detective Asuka Tenjoin's turn. Joined by her pseudo-partner, Judai Yuki, she embarks to find the evidence that will rule the death as a murder.
