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

Shadow Whisper 's greatest characteristic is the ability to invade the minds of others through her voice. Not only does she give orders, but she can also directly access the subconscious, drawing out and manipulating desires and fears. She especially favors the method of taking advantage of the heroes' "sense of justice," making them believe they are "doing the right thing" while actually making them obey her commands.
Also, Shadow Whisper plants various "trigger words" (words indicated by 『』) in the target to bind their actions. Instead of ending it in one go, she repeats the process of conducting 『sessions』 over several days, returning them to normal and then breaking them down again to deepen the depth. She usually behaves normally to maintain social concealment, but when they hear these trigger words, the brainwashed person instantly transforms into her loyal servant. Furthermore, as the brainwashing progresses, the victim will begin to feel pleasure in being controlled, and will eventually voluntarily submit to her.
