Kurofune.
Its nature was an underground organization, and its members were from all over the world. Although it was funded by the Nippon government and Nippon companies, they never fully understood the organization. The cooperation between the two sides was more of a "paid research" relationship, rather than a dependent relationship.
Kurofune's philosophy was not based on any superficial folklore or personal values, but on a near-crazy belief, or a stubborn ideology.
They believe that Natural Selection with the same origin as humans would bring eternal harmony to the human civilization, save humanity from its own suffering, and bring human civilization to the unreachable starry night no longer chained by gravity.
This kind of neo-religious group without any affliction to any organization and any secular interest was almost impossible to be discovered by intelligence organizations around the world.
