Manami Kasuga

As Kyosuke’s reserved younger sister, this diligent homemaker manages the household chores with quiet precision. While she typically avoids using her telekinetic and teleportation abilities, a hidden, wilder side occasionally emerges. Though the anime portrays her simply as a supportive sibling alongside Kurumi, the manga reveals her secret desire to see Kyosuke and Ayukawa unite. Despite her observant nature regarding Kyosuke’s romantic struggles, she remains largely unaware of the complex tension involving Madoka.
