Maria Takayama is a nun featured in the series. She initially interprets the protagonist's written letter—expressing apparent remorse—as a genuine return to seek repentance, reflecting her inherent hope for redemption and tendency toward forgiveness. However, the letter conceals a vertical message revealing the protagonist's true intent: a demand to see her underwear. Upon uncovering this deception, her demeanor shifts to visible disappointment and skepticism, particularly when hearing his pledge that this would be the "last time." Her expression conveys recognition of his recurrent behavior, eroding her belief in his repentance. Despite her disillusionment, she fulfills the underwear request while contorting her face in disgust. This encounter highlights her role confronting hypocrisy, testing her vows against the protagonist's unrelenting actions.
