Hana 邑史, a third year high school student, and his friend witnessed the trading scene of an organization that was hostile to Takaakira NAKAKAWA, the third president of Black Dragon Society. Later, the historical world attacked by the organization not only lost his memory but also changed his character by 180 degrees. Takaakira was pleased to take care of the historical world who was eager to patronize him like a stray kitten, but he felt sorry for the trauma that the historical world had never exposed. One day, when Takaakira's memory almost returned due to a flashback, he left the dormitory to inform his friends of the danger.
