Soryuin Shion (奏流院 紫音, Sōryūin Shion; "Shion Soryuin") is the board chairwoman of the Koyo Academy Group and a member of the Kengan Association.


Shion is a definitive woman with long dark red hair, full lips with neatly applied lipstick and a generally unimpressed expression covering her face. She has a notably large bosom and wears formal clothing in such a way that shows her assets off. Shion can usually be seen smoking a cigarette or at least with a cigarette on her person.


She is a wary persona, with surprisingly masculine tendencies.[1] Her muscle fetish is one of the main reasons she dated Hatsumi. According to her younger sister Soryuin Akemi, Shion told her to go after men with big muscles over handsome men.[3] She quietly enjoys the brutality and carnage surrounding and within the Kengan matches.

Despite her strictness, she is surprisingly doting to her sister Akemi, using her connections to get her sister into various gyms, including Silverman's Gym.[3] She once allowed Akemi and her friends to use their private jet to go to america, just because Akemi asked her.[4]


Eighteen years ago, while she was still in high school, she first met and soon started dating Hatsumi Sen for the first time.[2] During that time, he took Shion to Tochigi Destiny Land but they had a fight and broke up afterwards because she caught him cheating.[5] Two years after they first started dating, Hatsumi left again, telling Shion he was going on a journey to fight powerful fighters, but Shion saw the truth when she picked up an adult tour programme that he had dropped. Years later, Shion reencountered Hatsumi at his debut Kengan match where she saw him flirting with the Nogi Group's new secretary.[2]


Kengan Ashura

She was first seen watching a battle royale of 37 fighters with Matsuda. She witnessed in shock as Kiryu Setsuna defeated Ozu Toshio and made him her new fighter.[6]

On the S.S. Kengan, she was approached by Nogi Hideki with the promise of a ceasefire.[7]

At the Kengan Annihilation Tournament first round, she watched Kiryu’s fight against Nikaido Ren alongside Matsuda up until his overwhelming victory.[8]

At the second round, she watched Kiryu's fight against Kuroki Gensai as well, witnessing his seemingly fatal defeat.[9] She was left shocked after seeing Kiryu casually walk away despite getting stabbed in the heart. When she went to see him in the morgue, Kiryu gave the visibly unnerved Shion a chilling monologue. She was left worrying, wondering if she had broken a taboo.[10]

During the fight quarter-final match between Kanoh Agito and Hatsumi Sen, Shion worried about his condition after the Floating Cloud was overwhelmed and defeated by the Fang of Metsudo.[11]

Kengan Omega

Being called into an emergency Kengan Association board meeting, she and other Association members discussed the upcoming competition between the Kengan Association and Purgatory as well as the recent murder of an individual impersonating Yuzaki Mumon.[12]

Notes & Trivia
