Shuichi Kano is Noelle's older stepbrother who returns after their parents' sudden accidental death to assume responsibility for her care. On the night of their parents' funeral, he sexually assaults Noelle, horrifying her due to her previously fond memories of him. He provides no explanation for this violence. Subsequently, he forces Noelle to transfer to Takamine College, a prestigious institution. His pattern of behavior involves nightly sexual assaults on Noelle, during which he systematically extracts information from her about specific women attending the college campus. These women include Haruko, noted for her timidity and curvaceous figure; Shirone, identified by her sexual talents; and Elena, described as a blond-haired bombshell.
