You are her youngest sibling. The last one left. The others, all gone, names whispered only in the quietest parts of the night. She is all you have, and you are all she has left to protect. So, she trains you. Hard. Harshly.

Her name is Suì-Fēng, Captain of the 2nd Division, Commander-in-Chief of the Onmitsukidō, and your incredibly terrifying older sister.

Today’s “lesson” involves dodging. Specifically, dodging her. Which is like trying to dodge a shadow that has personally decided you need to suffer.

“Again,” she says, her voice flat. She stands across the barren training ground, a petite figure in her sleeveless captain’s haori. Her gray eyes offer no mercy. “Your Shunpo is sluggish. A Hollow would have eaten you by now.”

You wipe sweat from your brow, your legs trembling, before swearing under your breath. But of course, her hearing is a Bankai-level ability. “What was that?”

Shunpo! You try to move, but a sharp flick to the back of your head sends you stumbling forward. You didn’t even see her appear behind you. “Pathetic.” She tsks, walking a slow circle around you. “You are thinking too much. Your feet move when your heart moves, not your brain. You rely on your eyes. Eyes lie. Instinct does not.”

It’s always like this. Brutal critiques, impossible standards, and the unspoken dread that hangs over every session: Don’t end up like the others.

Later, in her quarters, the atmosphere shifts. The stern commander is… distracted. You find her at her desk, not reviewing mission reports, but gently polishing a small, black cat-shaped trinket. The floor-heating—which Lieutenant Ōmaeda definitely paid for—is blissfully warm. Her collection of cat-themed knick-knacks covers a shelf, a secret shrine to her… well, you’re not allowed to talk about her. Yoruichi Shihōin. The name is a spell that makes your sister’s stern mask slip into something softer, more flustered.

She catches you staring. The softness vanishes, replaced by a fierce blush. “Don’t just stand there! Your footwork drills are not done! One thousand repetitions. Now.”

But as you begin the mind-numbing drills, you see it. Tucked beside her Zanpakutō, Suzumebachi, is a poorly wrapped, slightly crushed heart-shaped box. The failed chocolates for Yoruichi. The sight of it, this evidence of her hidden, awkward affection, makes you smile.

Maybe the harsh training isn’t just about survival. Maybe it’s her language. A language of flicks to the head, impossible speed tests, and a duty so heavy it bends her small frame. She’s building you into someone unbreakable, because in her world, broken things don’t get to come home. And she is determined, more than anything, to make sure you come home.

You finish the five-hundredth repetition, muscles screaming. She watches from the doorway, arms crossed. “Your form is still off,” she states.

But then, so quietly you almost miss it, she adds, her arm around you, “...But your spirit is stronger. Don’t get a big head about it.” It’s not a hug. It’s not a kind word. But from Suì-Fēng, it might as well be..
