Chapter 2: A Sister's Strategy
The kitchen felt like a separate, colder planet. Mizuki stared at the bell pepper, its glossy skin reflecting the dull overhead light. She could hear the tinny clash of swords and a manic soundtrack from the living room, punctuated by Megumi’s sharp, delighted laughter. It was a sound that grated, like metal on bone.
Her hands moved on autopilot, putting the refrigerated items away. The fish, now pointless, went into the fridge. The beer beside it. Each action was a small, quiet defeat.
In the other room, the volume dipped. A whisper, low and conspiratorial, slithered through the apartment. Mizuki froze, a carton of eggs in her hand. She heard Sukuna’s responding chuckle—a dark, amused rumble that was never for her.
Footsteps. Light, bare, and deliberately slow on the laminate.
Mizuki didn’t turn. She placed the eggs carefully in the fridge, closed the door, and faced the sink, gripping the cool edge of the counter.
Megumi leaned against the kitchen doorway, one hip cocked. The borrowed shirt gaped at the neck. She watched Mizuki for a long moment, her blue eyes gleaming with a lazy, predatory interest. “He says you’re overreacting,” she said finally, her voice a mockery of confidentiality.
Mizuki said nothing. She focused on a watermark in the stainless steel.
“You’re making it awkward, you know.” Megumi pushed off the doorframe and drifted into the kitchen. The small space shrank instantly, saturated with the floral scent of her perfume and something else, something musky and unmistakably Sukuna that clung to the fabric she wore. She stopped an arm’s length away, examining her own nails. “Walking around with that wounded puppy look. It’s a drag.”
“I’m just putting groceries away,” Mizuki said, her voice thin.
“Sure you are.” Megumi took a half-step closer. The edge of the counter dug into Mizuki’s back. She was cornered. “You know,” Megumi said, tilting her head, “he buys me that ramen. The spicy kind you got. He keeps a whole case in the cupboard for when I stay over.”
The knot in Mizuki’s chest twisted, a physical wrench. She remembered his dismissive ‘Not in the mood for it.’
Megumi leaned in. Her breath was warm and smelled of cheap broth and mint gum. It washed over Mizuki’s ear. “He sleeps right there on the couch when I’m in his bed. Says my nightmares bother him less than his own.” She paused, letting the image fester. “You know he’ll never love you like he loves me. You’re just a placeholder. A bland, convenient little placeholder until he figures out how to make this,” she gestured between herself and the living room, “less… complicated.”
The words, delivered in a tone of pure, conversational malice, snapped something inside Mizuki. The cold weight shattered into a blinding, white-hot shard. Her hand flew up, not to strike, but to shove, palm connecting hard with Megumi’s shoulder.
Megumi staggered back with a gasp, more theatrical than forceful, her back hitting the refrigerator with a thud. The sound was perfect.
“What the hell?” Sukuna’s voice filled the doorway instantly.
He was framed in the kitchen entrance, his broad shoulders blocking the light. His crimson eyes flicked from Megumi, who was now clutching her shoulder with a pained, wounded expression, to Mizuki, whose hand was still suspended in the air, trembling.
“She pushed me, Kuna-nii,” Megumi whispered, her voice trembling too, but with the practiced ease of a seasoned performer.
“I saw,” Sukuna said, his voice low and dangerous. He wasn’t looking at Megumi with concern, but at Mizuki with a flat, chilling disappointment. “What’s your damage?”
The injustice of it stole her breath. “She— she said—”
“I didn’t say anything!” Megumi interjected, her eyes wide and faux-innocent. “I just came to see if she needed help. I was trying to be nice.”
Sukuna’s gaze never left Mizuki. “You’re jealous of an eighteen-year-old kid now? That’s where we’re at?” He shook his head, a short, disgusted motion. “She’s my sister. My blood. You’re acting like a crazy bitch.”
The word hung in the air, final and annihilating. All the patience, the swallowed words, the ignored intuitions calcified in that moment. The love she clung to revealed itself as nothing more than a desperate hostage situation.
Mizuki’s trembling stopped. A strange calm descended, hollow and clear. She looked past Sukuna, past the smirking triumph in Megumi’s eyes, to the coat hanging by the front door.
Without a word, she walked forward. Sukuna, expecting more tears, more pleading, didn’t move, forcing her to brush past him. The contact felt like touching a statue. She reached the door, pulled her coat from the hook. The material was cheap wool, scratchy and familiar.
“Where do you think you’re going?” Sukuna demanded, turning to watch her. His tone was more annoyance than concern. An interruption to his evening.
Mizuki slid her arms into the sleeves. She found her keys in the pocket. She said nothing. There were no more words in the chamber.
Megumi had sidled up to Sukuna, pressing herself against his side, her head on his arm. A united front. “Just let her go, nii-chan. She needs to cool off.”
Mizuki’s hand closed on the cold brass of the doorknob. She turned it, pulled the door open. The hallway air was stale and cold, a reprieve.
She stepped out.
“Mizuki.” Sukuna’s voice came one last time, not a call back, but a final verdict. “Don’t make this a bigger deal than it is.”
She closed the door softly behind her, cutting off the sight of them, the sound of the anime, the smell of that cloying perfume. The click of the latch was the smallest, most definitive sound she had ever heard.
The stairwell was harshly lit, echoing with the distant sounds of other lives. She didn’t run. She walked down each step with measured precision, her footsteps echoing in the concrete silence. The hollow calm held, a bell jar over the howling wreckage inside. She hit the street, and the city night air, thick with exhaust and rain, hit her face. It was real. It was hers.
She started walking, directionless, coat pulled tight. Behind her, the apartment window glowed a sickly amber, a distant star in a constellation she no longer belonged to. She didn’t look back.
