Satsuki Ichinose

Born to Nana Komatsu, this young girl appears briefly as a six-year-old, offering a glimpse into the series' future. Though her parentage remains a mystery, her black hair and hazel eyes strongly suggest Takumi is her father. Originally nicknamed "Sachiko" by Hachi and Takumi, she eventually received the name Satsuki through Ren's help. While she harbors a secret crush on Shin, her childhood innocence defines her rare but memorable appearances throughout the story.
