Soichiro Akizuki (Black Sun)

is the father of Nobuhiko Akizuki, and was a scientist who used to work under Michinosuke Donami in his research to bring the Creation King into being.
==History==
During the second World War, Soichiro was one among many scientists recruited by then Prime Minister Michinosuke Donami in a project to turn humans into weapons of war. In this time period, he expressed his doubt regarding the project to his colleague Kozo Minami, saying that he only wished to use the fruits of his studies to bring about world peace some day.
One of the scientists' subjects turned into a grasshopper monster, killing many people in its wake, with both Soichiro and Kozo witnessing the whole event. The two carried on their research under the orders of the government, and the grasshopper monster would eventually be renamed "the Creation King", thus successfully bringing about the existence of Kaijins, as well as Heat Heaven made from its extracts.
Some time later, on another day of a solar eclipse, Soichiro and Kozo experimented on their own sons Nobuhiko and Kotaro, giving them two halves of the Kingstone. The fathers believed that their sons would never fight against each other for the artifact, and would instead work together either to create a new Creation King or to kill it should something go wrong in the future.
By 2022, Soichiro had been confined to a nursery home due to his poor health as an old man. He had trouble speaking without the aid of medical equipment, but was still lucid enough regarding his own past. When Bilgenia and Aoi Izumi came to his place, with the latter holding the document detailing the origins of the Creation King in hand, Soichiro told them the whole truth. He revealed his past involvement with the government project and the true nature of the Creation King as a pawn without free will meant to be used just for the extracts. Before the two left the nursing home, Aoi asked him how the Creation King could be killed for good, to which Soichiro replied: "the Satansaber".
