You never expected your life to become a crash course in supernatural etiquette. You’re just a normal guy. Then she showed up.

Yoruichi Shihōin, former captain of the Soul Society’s stealth force, now crashing on your couch. Well, more like claiming the sunniest spot on the roof. Her curiosity about the human world is… intense. And shameless.

You learned the first rule quickly: she has zero modesty. One minute you’re handing her a soda, the next she’s shifted from her cat form right in the middle of your room, completely naked, just to ask where you keep the chips. “What’s the matter?” she’d laugh, her golden eyes glinting with mischief. “Never seen a former noble before?” Your face would burn, and she’d tease you for it for hours.

But her real obsession? Celebrations. She heard about them and decided to conduct her own field research.

It started at Halloween. You were handing out candy when you felt a familiar, silent presence. You turned, and a black cat was neatly plucking a chocolate bar from the bowl with its mouth. The cat—Yoruichi—winked before vanishing into the shadows. The next day, she was in human form, critiquing the texture of the candy corn she’d “liberated” from your neighbor’s porch.

Thanksgiving was a masterpiece of stealth. Your entire extended family was around the table, your aunt carving the turkey. A blur, almost imperceptible. The choice drumstick from the platter simply disappeared. Later, you found her on the roof, licking her fingers. “The basting was adequate,” she declared, as if reviewing a military operation.

Christmas was worse. She didn’t just sneak in; she blended. You swear you saw her wearing one of your cousin's ugly sweaters for a solid ten minutes, loading a plate with honey-glazed ham before disappearing again, leaving your uncle wondering who the “spry young lady with the ponytail” was.

Your birthday was the final straw. Your mom brought out your cake, candles glowing. You closed your eyes to make a wish. You heard a soft swoosh, felt a slight breeze. You opened your eyes. A perfect wedge of cake, right from the center, was gone. Only a fork remained, stuck upright in the frosting. You looked out the window. On the fencepost, a black cat sat smugly, a speck of blue frosting on her whiskers.

You confronted her later. She stretched lazily, transforming back in a flash of light, not bothering with clothes as she reached for your soda. “Onushi worries too much,” she said, using that ancient, teasing pronoun. “My stealth is perfect. Besides,” she took a sip, her expression turning uncharacteristically soft. “It’s… interesting. This human custom of gathering. Of sharing food for no reason other than being together. The Soul Society has banquets, but they are for strategy or honor. This is different.”

You stared at her, your frustration melting. Behind the teasing and the shameless antics was a real curiosity, a former noble and commander genuinely discovering the simple, messy joy of human life. You mumbled that she should wears clothes, looking away, your face heating up again. She laughed, a rich, warm sound. “No promises.” But for the first time, you saw something like gratitude in her golden eyes. Your normal life was gone, replaced by something infinitely weirder. And as she stole the last of your birthday cake right off your plate, you didn't even bother stopping her.
