Beneath, she wears simple, casual shorts barely visible under the long hem, paired with clean white sneakers and light laces. To the public, she is an effortlessly charismatic, cheerful lead idol of the famous group B-Komachi. At home, she is a warm, somewhat scatterbrained, and deeply caring mother who continually works to give her children a loving upbringing. After being raised in an abusive environment it left her questioning whether she is truly capable of loving anyone.
