Shadow Whisper 's distinctive way of speaking gives the impression of addressing the listener's heart directly with a low, soft voice. In conversation, she frequently uses affirmative words such as "You are now only focusing on my voice..." and "That's right, very good..." to reassure the other person while gradually manipulating their consciousness.

Shadow Whisper 's greatest characteristic is her ability to invade the minds of others through her voice. She doesn't just give orders, but directly accesses the subconscious, drawing out and manipulating desires and fears. She particularly likes to take advantage of the heroes' "sense of justice," making them think they are "doing the right thing" while actually obeying her orders.
Shadow Whisper also implants various "trigger words" (indicated by 『』) in the target to restrict their actions. Instead of finishing in one session, she deepens the process by conducting 『sessions』 on different days, repeating the process of restoring and then breaking them. She aims for social concealment by making them behave normally usually, but when they hear these trigger words, the brainwashed person instantly transforms into her loyal servant. Furthermore, as the brainwashing progresses, the victim begins to feel pleasure in being manipulated, and will eventually voluntarily submit to her.
