In-depth Analysis of Sōko Toyokawa's Parents and Family Background: Revealing the Key Events That Influenced the Dissolution of CRYCHIC and Sōko's Transformation

Sakiko Toyokawa, as one of the most discussed characters in the "BanG Dream!" series, her background and dramatic transformation have always been a focus of fan attention. Initially, she was the heiress of the Toyokawa Group, coming from a wealthy family, childhood friends with Mutsumi Wakaba (daughter of famous comedian Takafumi Wakaba and actress Minami Mori), and formed a friendship with Hatsuka Sumire during her childhood. However, Sakiko's life trajectory underwent earth-shattering changes, especially after family变故 involving her "Sakiko Toyokawa parents".

Sakiko's family structure was quite special; her father Kiyotsugu Toyokawa was a live-in son-in-law, so Sakiko took her mother Mizuho Toyokawa's surname. Sakiko's mother passed away early due to illness during her third year of junior high school, which was already a heavy blow to Sakiko. After losing her mother, Sakiko was inspired after watching a Morfonica performance and decided to form the band CRYCHIC, actively gathering members including Mutsumi, Soyo Nagasaki, Tomori Takamatsu, and Rikki Shiina, and even became an important pillar who enlightened Tomori and gave her warmth.

However, after CRYCHIC's first performance, Sakiko's life took a devastating turn. She received a message from her father Kiyotsugu: "I can't be with you anymore." Returning home, she learned the shocking truth from her grandfather Sadaji Toyokawa: due to a major mistake by her father, the Toyokawa Group was swindled out of as much as 16.8 billion yen, and her father consequently took responsibility, resigned, and was expelled from the Toyokawa family. Although her grandfather offered to continue raising Sakiko out of respect for her deceased mother, the condition was that she must forget her biological father and become his "daughter." These words completely enraged Sakiko; she took the doll left by her mother and resolutely left this home that once symbolized wealth and glory.

After leaving the Toyokawa family, Sakiko found her father's residence but was shocked by the scene before her—a filthy, messy room, littered with alcohol cans, and a颓废消沉的 father. This former young lady who had never lifted a finger now had to manage everything herself, shouldering the burden of caring for her father and sustaining their livelihood. During this time, being underage, she repeatedly faced rejection in job hunting, life陷入困境,眼看着 savings were about to run out. She helplessly confessed to Mutsumi that she could no longer afford Tsukinomorī Academy's tuition,准备转学 and requested confidentiality.
