The nightmare didn't end with Tuoka's fainting; Tuoka woke up once more, but this time it wasn't of his own accord, it was the excruciating pain that roused him!
At this point, Tuoka started to harbor an illusion that he might actually be undergoing the Devil's trial in the legendary Hell. Otherwise, how could a living person endure such torturous agony? The pain was enough to drive a person mad with life. If he could choose again, he would have never allowed himself to be seduced by that waitress, then he wouldn't have to suffer such inhuman suffering.
Cold sweat continued to form on Tuoka's body, and he was convulsing non-stop, not just his body but also his internal organs were trembling ceaselessly. Such pain was beyond description by words. Had there not been a person standing before him, Tuoka would have truly thought he was already dead.
