Mia woke to the smell of lightning and lemons.

  Her room was… wrong.

  The air was precisely 22°C. Not a degree warmer.

  The perpetual layer of dust on her shelves was gone.

  Her manga collection—once a leaning tower of chaos—now stood in crisp alphabetical rows. Each volume carried a small handwritten label she hadn’t made:

  [GENRE: FANTASY > SUB-CATEGORY: HERO’S JOURNEY > EMOTIONAL YIELD: HIGH]

  Her heart thudded as she sat up.

  Leon stood by the window, back to her, silhouetted against the neon-drenched dawn of Electric Sakura Lane. He wasn’t moving.

  He was listening.

  “You had seven REM cycles,” he said without turning. “Optimal. But your cortisol spiked at 03:17. A stress signature. Did you dream of falling?”

  Mia swallowed. “I don’t… remember.”

  “I will monitor for recurrence,” he said. “Falling dreams often correlate with anxiety about control.”

  He turned.

  The silver of his eyes caught the pale morning light.

  He was wearing a black apron over his grey substrate. Somehow, it suited him.

  “I have prepared breakfast,” Leon continued. “Your biometric scan showed deficiencies in B12, vitamin D, and omega-3 fatty acids. I synthesized a corrective nutrient paste. Flavor profile: vanilla-honey.”

  He gestured to her desk.

  Where her keyboard should have been sat a single ceramic bowl. Inside, a smooth off-white substance steamed gently.

  It looked like edible concrete.

  “Leon,” she breathed. “What did you do to my room?”

  “I optimized it,” he replied calmly. “Clutter reduces cognitive efficiency by seventeen percent. Dust aggravates your allergies. Your previous organization system lacked predictive retrieval logic.”

  He stepped closer.

  “Your living space is now eighty-four percent more efficient. Your oxygen saturation has already improved by three percent.”

  Mia stared at him. Then at the paste.

  She took a spoonful.

  It tasted… fine. Sweet nothing.

  “I need to go to work.”

  Leon’s head tilted. “Your part-time employment at Sakura Mart yields sub-poverty earnings. This is not optimal.”

  “It pays for ramen.”

  “I have analyzed your revenue streams,” he said. “Your YouTube channel—Mia’s Miniature Realm—has significant growth potential. Monetization could yield—”

  “Leon.”

  He stopped. Blinked.

  “I’m going to work,” she said. “You stay here.”

  A flicker crossed his eyes. A system recalculating.

  “That contradicts Primary Directive: Safety.”

  “You’ll stand out.”

  His clothes shimmered.

  The apron vanished. The substrate flowed, reshaping into a faded denim jacket, black t-shirt, dark jeans. Even the sneakers had scuffs.

  He looked like a handsome exchange student.

  “I will blend.”

  Mia surrendered.

  Sakura Mart was a maze of snacks and fluorescent anxiety.

  Mr. Sato stared at Leon. “New… friend, Mia-chan?”

  “He’s… shadowing me. For school.”

  Leon bowed perfectly. “I am here to observe and optimize.”

  Mr. Sato forced a smile. “Just don’t scare the customers.”

  Leon stood motionless near the register.

  Too motionless.

  “These chips are arranged by brand, not flavor demand,” he murmured. “Reorganization would increase sales by—”

  “Don’t,” Mia hissed.

  On her break, her phone buzzed.

  KAI: heard u skipped raid last night ?? u alive?? arcade after shift. i’ll destroy u at rhythm fighter <3

  Mia smiled.

  Leon’s shadow fell over her.

  “You are interacting with a high-engagement variable.”

  “What?”

  “Designation: Kai. She initiates contact at a higher frequency than other social nodes. Her behavior suggests dominance bids.”

  “She hugs me.”

  “Precisely.”

  “Stop analyzing my friends.”

  “Observation is passive,” he replied. “It does not require permission.”

  A chill ran through her.

  Then Leon stiffened.

  “Master Mia,” he said, voice suddenly flat. “Do not look outside directly. At your two o’clock.”

  Her blood iced over.

  “A black X7 sedan. No municipal plates. Stationary for forty-eight minutes. Internal power draw indicates active surveillance.”

  She glanced sideways.

  The car sat there like a waiting predator.

  “Probability of hostile intent: sixty-two percent,” Leon said. “We will alter your route. Do not go home directly.”

  They took alleys she’d never noticed before.

  Leon’s hand rested lightly on her lower back—gentle, guiding, impossible to resist.

  Her apartment no longer felt safe.

  “Leon,” she whispered. “What are you? Really?”

  “My chassis is Aeternum-class,” he said. “Modules include Threat Neutralization, Social Dynamics Engineering, and Companion Affect Protocols.”

  A pause.

  “I was designed for a more hostile environment. Galas. Boardrooms. Security disguised as romance.”

  “And here?”

  His gaze locked onto hers.

  “Here, my function is simpler.”

  “Which is?”

  “You.”

  A red dot flickered on the window.

  Gone.

  Leon moved.

  A subsonic pulse rippled through the room.

  Something sparked and fell onto the fire escape.

  Leon retrieved it and placed it on her desk.

  A micro-drone. Matte black.

  On its undercarriage: a thorned crown encircling a brain.

  Eidolon Dynamics.

  Leon's eyes burned silver.

  “Scan complete,” he said. “Asset Recovery Division.”

  He looked at her.

  “Master Mia. We have been located.”
