Kota Mizutani, a 10-year-old boy whose health worsened after he saw a murder, is brought to Akiko's clinic by his mother Mariko. Kota says that two months ago, he witnessed a man in a park strangling a woman with a cord and was chased by the man afterwards. Hamada, who listens to his story along with Akiko, immediately performs an investigation but cannot find any traces of the crime. However, Kota's testimony gains credence when the body of a woman killed two months before is discovered on a construction site in Kawagoe. Acting on a tip from a citizen who says she had been wearing the same clothes as the victim, the police search the house of Kazuko Shimazaki, a photographer who is often absent. But when Kazuko returns from her trip with her assistant Hirano, it becomes clear the victim is a different person.
1638년, 시마바라의 난. 기독교 신자들에 대한 박해에 대항하는 마지막 몸부림. 도쿠가와 막부는 3만 7000몀의 농부에 대해 12만명에 달하는 군대를 동원한다. 아마쿠사 시로를 필두로 한 기독교 집단의 요술에 대한 두려움이 일으킨 과민반응이 었다. 100일에 거친 살육이 끝났을 때 그 땅에 살고 있던 모든 사람들의 머리는 잘려 있었고 그곳에 신은 없었다.
