Ichinose, Satsuki
Summary
As the daughter of Nana Komatsu, Satsuki remains a largely enigmatic figure who appears only sparingly toward the end of the narrative. Her debut occurs when she is six years old, a scene that likely offers a glimpse into the future. During Nana’s pregnancy, both Hachi and Takumi unofficially referred to the unborn child as "Sachiko." Although it remains unclear whether she is the biological daughter of Takumi or Nobu, she bears a striking resemblance to Takumi, sharing his black hair and hazel eyes. It is revealed that she harbors a crush on Shin, though it is improbable that he reciprocates these feelings or is even aware of them. Her given name, Satsuki, was selected by Ren at Hachi’s request, as Hachi could only think of the nickname "Sachiko" at the time.
