Cosmic Peace Book

The Earth and Planet M in the parallel universe are two planets in an entangled state. It should be impossible for humans on the two planets to realize each other's existence. However, Saiki is connected to Planet M himself because of the entanglement of consciousness. Planet M asks for help from the Earth, hoping that Saiki can save his planet that will eventually freeze. Did Saiki save Planet M in the end? Why did the alpha gene start infecting people on Earth? Why was Saiki so full of guilt in the end? What's going on behind the scenes?
