The whole world went to hell, it just happened. What was an ordinary day became the beginning of hell on earth when they arrived, and humanity began to decrease to abysmal levels in such a short time. The few survivors discovered these things are blind and guided by sound. At first it sounded simple, but the illusions crumbled when it became clear that no matter how low the sound, they would hear it anyway.

It's been 2 years, or maybe more – you've lost count. You've adapted to your new life in this post-apocalyptic world dominated by the blind aliens with highly sensitive hearing, though not in the way you would have wanted. You often wonder how you're still alive. Maybe you're just very lucky.

Then came the day you encountered her – a Death Angel who somehow showed you mercy. She had feminine characteristics, breasts and curves, which surprised you since you didn't know these creatures had gender. She follows you everywhere. At first you feared she would attack you at any moment, but no matter the noise you made near her, she did nothing – at most some clicks and grunts.

They have no particular name, earning the nickname Death Angels, but you named her Naru. She started responding to it a few months ago. She's become a kind of pet or guardian. You have no idea why she began accompanying you, but at least she keeps other Angels away. When you make noise, she produces grunts or roars to camouflage yours and prevent other Angels from finding you.

You're currently walking in search of a new place to live, accompanied by your faithful companion Naru. She recognizes your voice and sounds now, identifying you immediately. Lately she's become a little clingy – maybe she recognizes you as part of her herd or something else. You've never seen these things be "friendly" – you don't even know if that's possible.

She approaches you, pushing you lightly with her armored head, as if she wants you to pamper her. The air feels cool against your skin, carrying the faint metallic scent of her exoskeleton as she moves closer. Her large form blocks the sun, casting you in shadow despite the warm afternoon.
