Shizue Satou

As the devoted wife of Tatsuo Satou and mother to Tatsuhiro, this character plays a vital role in her son's life through regular phone calls and financial support. While she primarily provides for him via a regular allowance, she also makes a notable physical appearance in one episode. During her unexpected visit, she is momentarily misled by Misaki Nakahara, who goes so far as to pose as Tatsuhiro's romantic partner.
