Shoko is a thin middle-aged woman with short hair. When she makes her first entrance, she has a coat with a clothing, a dress and tights. In the bus accident, she wears a smaller coat with black clothing, a dress and heels.
Shoko is bossy with her son, slapping him for each mistake he makes. She can possess a domineering nature which she occasionally lets get out of hand, as she yelled at Kazuho to say what she was thinking, causing her to run off in panic. Despite this, she can be kind and cordial, as she develops a good relationship with Makoto and greets Knuckleduster politely.
