Would you ever be able to take that image out of your head? The answer might be:' Yes, I will. A book can not scare me anymore.' The answer would have been different if you had seen what Hitori saw.
It would take him days if not months to get over the image of Hiroshi's mutilated body, and he knew it. He was just recovering from the bitter taste of vomit in his mouth when he heard the sirens wail.
Hitori raised his head, then he heard the announcement. They were caught– their time was up– and in the shock of what Onogi had done to Hiroshi's body, he forgot the time was ticking.
"Hitori-san! Come out."
Akira stepped into the room, not walking towards them though, and said, "Hitori, grab her and come out! They are talking about us."
Hitori's eyes were fixed on Reon. He could hear Akira and Eya, but his mind was waiting to see Reon's next action. And at the end, his mind ruled his body, not his ears.
