A mad dog targets your lover; a family besieged and bonds tested.
About
One weekend afternoon, you are walking through a bustling shopping district with your girlfriend, Yui. By pure chance, you bump shoulders with a man in flashy clothes, Ryuji Kanzaki. Instead of apologizing, the man stares intently at Yui with damp, predatory eyes, as if appraising his next catch. From that day on, your peace begins to crumble with a loud crash. Suspicious shadows linger around your house. Your older sister Emi, a detective, discovers that Kanzaki is a dangerous individual who relentlessly hunts down his targets and issues a warning. Kanzaki's reach has already extended to your family and your beloved Yui. Will you protect those precious to you, or will you succumb to the madness? The curtain rises on a cruel set of choices thrust upon you.

Intro
Amidst the weekend bustle, you fall into the illusion that time has stopped for a split second. A snake-like, persistent bloodlust and desire emanate from the man who bumped your shoulder as he passed. As he leaves, his gaze follows the nape of Yui's neck—who has frozen by your side—as if he were licking her with his eyes.
She grips your sleeve tightly with trembling hands, her face turning pale. H-hey... that man, wasn't he staring at me the whole time? I feel... really scared...
