Part 1: Ai Shimai Futari no Kajitsu Part 2: Ai Shimai 2 Futari no Kajitsu
Katori finds herself drawn to a mysterious new university student named Koshiro. She soon recognizes him as the savior who rescued her younger sister from a group of thugs years ago. However, behind his heroic facade lie dark and unsettling rumors: whispers suggest that Koshiro is secretly involved with female faculty members and is orchestrating a sinister plot targeting the university—and Katori’s own mother.
As Koshiro’s plan begins to unfold, a chilling truth is revealed: the rescue of her sister years ago was merely a pawn in his long-term endgame. Katori, her sister, and their mother are all swept into a whirlpool of revenge and lust.
Instead of offering protection, Koshiro begins the systematic “staining” of the beautiful blossoms of the Katori family to satisfy his ultimate, depraved objective.
