Shuuko Nimi is the wife of Masayoshi Komi and the mother of Shouko Komi and Shousuke Komi. She looks like her daughter, but Shuuko's personality is like that of a teenager and she introduces herself to Tadano and Najimi as forever 17 years old, methaphorically. Shuuko has an outgoing, friendly and socially confident personality who is always the chatterbox of her family as both her children take after their father Masayoshi, who is a very silent man.
