Conan's Mystery and Severn: Line of Defense Across the World

In the bustling and bustling Yoneka Town, there are undercurrents surging beneath the calm surface. A series of bizarre murders with strange methods and unsolvable methods occurred one after another. When the conventional investigation reached a desperate situation, the Earth Defense Force's third-generation Ultra Guard was ordered to intervene. The hot-blooded and forbearing Masaki Fengmori, who has a sense of civilization, the calm and decisive Captain Bai Yong, the paranoid and radical hawk consultant He Zhi who cares about the safety of the earth, and a group of team members who shoulder the mission of protection, have since then fought side by side with Edogawa Conan, Mouri Kogoro, Sato Miwako and other people from the Metropolitan Police Department. There is no standard answer to justice. When the detective's reason meets the fate of the Ultra Warriors, when laws and regulations collide with alien threats, when the extreme methods of the Iron-Blooded Advisor collide with the goodwill of human nature, how can they defend the city and protect the ordinary daily lives of ordinary humans?
