Akia is the only child of Kase, the head of the biggest Yakuza clan in Japan known as the Kabashima clan, and Miyoshi.
She decides to enter the real-life Btooom game voluntarily after her father shares with her the list of participants which includes her fiance Emilia and Yoshioka Seichiro a man she absolutely hates because of a certain incident with Emilia.
At first, Kase denies this request but later accepts when Aika reminds him of how some of their men are hesitant of having a girl be next in line as the head of the clan and this will secure her place and earn her their respect.
