Klein's memories of the paper crane were still fresh on his mind. Back then, Will Auceptin had used this item to locate Dr. Aaron's Astral Projection and injected information into him while he was dreaming of the spirit world in his dreams. It created a revelation that evolved into a specific dream.
Klein later exchanged a paper crane, he had folded himself, for Will Auceptin's and had gone above the gray fog to make a divination. He failed to gain any effective conclusions until Dr. Aaron's wife got pregnant. By calculating the time and from his understanding of the situation between a Sequence 1 and Sequence 0, he guessed that Will Auceptin was performing a cyclic restart, and he guessed that Will was in an intense battle with another Snake of Fate for the position of Sequence 0. And the nightmare that came with the paper crane was only an auxiliary outcome. Its true purpose was to help Will Auceptin secretly become a fetus.
