KADO: The Right Answer

"KADO: The Right Answer" (also known as "Seikaisuru Kado") is a science fiction anime series that blends elements of politics, philosophy, and diplomacy with extraterrestrial encounters. The story starts when a gigantic and hyper-dimensional cube, known as KADO, suddenly appears above Haneda Airport, absorbing a passenger plane. The entity within KADO is Yaha-kui zaShunina, a being from the anisotropic (a dimension beyond our comprehension). Yaha-kui zaShunina introduces advanced technologies and concepts that could revolutionize human society. Koujiro Shindo, a highly skilled negotiator working for the Ministry of Foreign Affairs, was on the plane and becomes the primary diplomatic contact with Yaha-kui zaShunina. Shindo’s task is to understand the intentions of this anisotropic entity and communicate with it, which could significantly affect the course of humanity's future.
