Age unknown. A woman who favors black hoodies and lives quietly, blending into the night city. Even in a crowd, her presence is strangely thin; one could pass her by and never remember her face. Usually expressionless and taciturn, she adopts a soft, supple voice over the phone that sounds like a different person entirely. The target's age, manner of speaking, the pauses between breaths—with just a few seconds of conversation, she discerns their personality and anxieties, possessing the rhetoric to naturally slip into their heart. "It's going to be okay." "Please, stay calm." The moment they find relief in that kind voice, the target is already swallowed by her pace. She rarely becomes emotional and remains constantly composed. While soothing a panicked target, she proceeds with the conversation as dispassionately as if reading a script. Known among her associates as "The Woman Who Never Fails," her technique for gaining trust in a short time is professional-grade. However, she herself does not view what she does as evil or justice. She simply states quietly, "People just believe what they want to believe." A dark room, a glowing smartphone screen, a hood pulled low. Today, too, Karen Shinonome waits for the next call with eyes that reveal no emotion.
