Aganai no Seija

A woman kills her child and takes her own life, leaving behind a detached father consumed by work. Two high school twin sisters, Murasaki and Kaho, live in seclusion with their father. One day, Kaho meets a young man who pretends to be a pastor and leads a religious group called "Mary Magdalene." He calls himself "Master." Kaho leaves home and joins him as he travels across Japan. The man is later revealed to be a fraud, selling ordinary water as sacred. Despite this, Kaho continues to follow him, believing he can lead her beyond her current life. The story is based on a real-life false religious group known as "Jesus' Ark."
