Shion Souryuuin serves as the board chairwoman of the Koyo Academy Group and holds membership within the Kengan Association. She is also the former girlfriend of Hatsumi Sen. Their relationship began eighteen years ago when Shion was still a high school student. Hatsumi took her to Tochigi Destiny Land, but the couple eventually broke up after Shion discovered he was cheating on her. Two years into their dating period, Hatsumi departed again, claiming he was embarking on a journey to battle strong fighters. However, Shion uncovered the truth when she found an adult tour program that he had accidentally dropped. Years later, Shion ran into Hatsumi again at his debut Kengan match, where she witnessed him flirting with Akiyama Kaede, the new secretary of the Nogi Group.
