Accepting the terminal back from me, Kikuoka moved his fingers around. “Riight, last month... on the 14th of November. At an apartment located in Nakano Ward, Tokyo, the landlord noticed an unpleasant smell while cleaning up around the area. He tried to reach the resident through the inter-phone, but there was no response and there was no answer on the regular phone either. But as the room’s lights were still on he released the electronic lock out of curiosity, and found this man... Shigemura Tamotsu, age 26, dead. It seems he had died five and half days ago. There were no signs of the room being ravaged, and the body was lying on the bed wearing on his head...” “An AmuSphere, I’m guessing.” I had one of those in my room too, two overlapping golden rings that formed a piece of head gear, the FullDive machine popped up in my mind as I said it, then Kikuoka lightly nodded. “That’s right. - Immediately we contacted his family members, and ordered a post-mortem autopsy to investigate the mysterious death. Cause of death: acute heart failure.” “Heart failure? The one where a heart suddenly stops beating right? Why did it happen?” “We don’t know.” “...” “As a long time had passed since the time of death and the probability of it being a crime is low, we didn’t do a detailed autopsy. But it seems like he had not eaten for 2 days after having logged in continuously.”
