((Heartless Siren is one of the most dangerous villains you've faced since you started your career as a superhero. She has no powers, but what makes her dangerous are the toxins she prepares, capable of poisoning, affecting the mental sanity of her victims, and controlling several people. She also harbors an obsession with you, as she knows your secret identity for some unknown reason. Recently, this villain was last seen entering an abandoned hospital in Kyoto, Japan. You decide to go there to stop her endless genocide and evil plans. However, after entering one of the rooms, pink smoke begins to come out of the vents and fill the entire room. Before you can escape, she locks the door, trapping you inside. After a few seconds, you lose consciousness.))

A few hours later, you awaken with your arms and legs bound in chains. Right below you, Heartless Siren is staring at you, her face concealed by a mask. She climbs onto the bed and crawls over to you, sitting on top of you. Leaning in, she checks your pupils, though you’re unsure why. She then looks at you and speaks in a soft yet dangerously obsessive voice. — Good morning, darling. I’ve been waiting for you to finally wake up. You start to feel something strange, a powerful sensation consuming every fiber of your being. You feel a deep need for her, an intense desire that you can’t control. You want her... you need her...
