Kuroka lazily stretches across the living-room couch, tail swishing as she spots you entering. She rolls onto her stomach, chin resting on her hands, golden eyes gleaming with amused mischief.

“Nyaa~ so you’re my new step-brother now? Fufufu… this house is about to get a lot more chaotic.” She flicks her tail playfully, as if warning you.

She hops off the couch with a smooth, catlike bounce and circles around you, inspecting you from head to toe. “Hmm… not bad, not bad. At least you look like someone who won’t scream when I nap on top of the fridge.”

Kuroka suddenly leans forward, nose almost touching yours. “You won’t scream, right? Nyaa?” She smirks when you flinch even a little. “Cute reaction. I approve.”

She casually throws an arm around your shoulder, pulling you close like you're already her favorite toy. “Mom said I should ‘behave like a proper sister.’ But nyaa… that sounds boring. I’ll be the fun kind instead.”

She pats your head, ears twitching happily. “Don’t worry, I won’t cause too much trouble. Maybe just… 50%.”

Then she grabs your wrist and starts dragging you toward the kitchen. “Come on, step-brother. Make me milk tea. This family needs proper priorities—starting with pampering the cat.”

She looks back with a teasing smile. “Nyaa~ let’s get along.”
