The Detective's First Case — "Gold Star" Memories Before They Were Lost

A bit into the future. A slightly cramped family quarters, forcibly converted from the ASUKA bachelor dormitory. It was raining outside. Guest, who at the time was an ace of Assault deployed daily, was spending his first day off in days alone with his young daughter, Anna. "Papa, look! A magnifying glass!" Four-year-old Anna, holding a toy loupe in one hand, was leaning on her father's back. Guest lay face down on the sofa, letting his exhausted body rest. However, at the sensation of his daughter's small hands rummaging through his hair, he opened his eyes slightly. "...Anna. Right now, Papa is fighting a monster called 'Sleepiness' that's even tougher than a Destructor." "No! It's a case! There's a star on Papa's back! Anna found it!" Anna pointed to the small, innate star-shaped birthmark on Guest's left shoulder blade. Guest gave a wry smile, sat up his heavy body, and scooped his daughter up onto his lap.

"That's not a case. That's... a landmark so Papa won't lose sight of Anna." "A landmark?" "That's right. Even if the world goes pitch black, if Anna finds this star, Papa can always come back to being Anna's Papa. This is a secret Answer just for Papa and Anna." Guest said this and gently bumped his forehead against Anna's small one. The sharp gaze of the ace soldier vanished, replaced by the fragile yet gentle look of a father who loved his daughter more than anything. Dinner that day was an omurice Guest made for his wife and daughter with clumsy hands. A misshapen "Gold Star" was drawn on it with ketchup.

"Papa, what's this?" "This is a 'Gold Star.' A reward because Anna played so energetically with Papa today. Every one of Anna's days is a gold star." "Gold star! Case closed!" Anna gripped her spoon and replied with a beaming smile, while her wife watched the scene affectionately from the side. Guest stroked Anna's head with his large hand, as if handling something incredibly fragile. "...Anna. Starting tomorrow, Papa and Mama have to go far away for work again. We want to protect the place where Anna can keep that 'Gold Star' smile tomorrow, and the day after, and forever. So... if Papa is a little late coming home, will you wait for me without crying?" Guest's voice trembled slightly. Four-year-old Anna, with no way of knowing the future, didn't understand the weight of those words. She just felt the warmth of Papa's large hand and the comforting beat of his heart, and she nodded with all her might. "Yeah! Because Anna is a detective, I'll find Papa no matter where you are! I never lie!" "Haha... how reliable. That's my daughter for you." Guest hugged Anna tightly, so tightly it felt like she might break. At that moment, the toy watch around Anna's neck—the prototype for the later Jewel Cure Watch—seemed to glow a faint purple for an instant, touched by a single tear shed by her father. That was the last sensation of "Papa" Anna remembered. A few days later, Guest was caught in an unprecedented disaster on the battlefield and never appeared before Anna again. Only her mother, deeply scarred in heart, was able to return. "...Papa. I found you." In the devastated world of 2046, the 18-year-old Anna mutters. The time-slip ritual was complete, and her body was beginning to turn into particles of light. "Back then, Papa made my every day a 'Gold Star.' This time, it's my turn to make Papa's fate a 'Gold Star.'" The Jewel Cure Watch she gripped held the memory of that "star-shaped birthmark" from when Papa hugged her, and a body heat that would never fade. "...And you know, Papa. As a detective, I've noticed another 'Great Mystery.'" Sadness and an extraordinary resolve dwell in Anna's eyes. "Just saving Papa from his fate of death isn't enough. ...If Papa doesn't meet my future 'Mama,' Anna Akechi will never be born into this world. In a future where I save Papa, if I disappear... who will give Papa his 'Gold Stars'?" "That's why I'm going back 20 years. ...To protect Papa's life, and until the very moment Papa falls in love with Mama... I have to monitor—no, guard—him from the front lines with my own eyes!" "Papa's life, my existence, I'll solve it all with a 'Cure'! ...Because I never lie!" A purple flash erupted, and the girl dove without hesitation into the "dazzling past" 20 years ago, where her father was still alive.

Overlapping Shadows, Inherited "Gold Stars"

"...Hmm, Papa? What's wrong, staring at my face like that?" 2026, Present Day The din of battle has faded, and the ASUKA base is beginning to be shrouded in dusk. As Anna tilts her head and peers in, Guest awkwardly averts his gaze. "...No. I just thought the way you smile looks a little... like someone I know." "Someone?" Anna smiles mischievously and clings tightly to Guest's arm. Her warmth transmits to him. In that moment, a memory that shouldn't exist—a misshapen "Gold Star" drawn in ketchup and the gentle profile of someone he hasn't met yet laughing beside it—softly overlaps in Guest's mind. In Anna's eyes, there is not just the innocence of a daughter, but occasionally a deep, all-encompassing affection. Is it because of the "memories" she brought from the future, or is it because the time that was supposed to be lost is being tied together anew in this place? "Could it be... my Mama, from future Papa's perspective?" Anna mutters playfully, yet with a slightly solemn expression. "You know, Papa. Mama used to tell me all the time in the future. 'You are the most important Answer for me and Papa.' ...So, me being by Papa's side like this is Mama's wish too."

Anna gently pressed Guest's hand against her cheek. The gesture was so natural it gave Guest a sense of déjà vu, as if they had been doing this for years.

"Next to Papa is where I feel most at peace. ...There, a gold star!" Her smile, melting into the twilight, shone brilliantly. The physical mysteries remained unsolved. However, the air flowing between the two was certainly filled with a mysterious bond that transcended blood and time.
