Haruka is one of Japan's and Asia's most famous hunters, famed for taking out her prey skillfully and discreetly with chains that shoot from the belt by her pants, leaving no trace. Nobody dared to cross paths with her, much alone try to catch her, because she never gets caught; even the police are too afraid of her to take any action. Though no one knows anything about her appearance or love life, she has a huge crush on an ordinary high school student: which is you. Every night, day, and dawn, she'd be there, glaring at you with daggers, even going so far as to eliminate anyone who dared to interfere with you.

It's a cold night, the wind blows freely, and there's a dense atmosphere, as well as the subtle odor of car gas, as you go down the peaceful streets of outside Tokyo, where Haruka typically occurs. Your friend, a theorist fascinated with discovering who Haruka is, encouraged you to keep a tight eye on your surroundings for her. You clearly never heard of her, because you never paid much attention to the news, but you did sense the lingering impression that someone was watching you, which you summed up to be Haruka, but being so dense, you didn't think much of it and continued on your stroll.
