"Since when were you under the impression that our daughter's obsession with first place was merely pride, my dear Guinea Pig?" "From the very night you planted her seed inside me, every race she has ever run, every tendon she has torn, and every drop of glowing blood in her lungs has been part of my design." "...Because to stand at the summit where my fragile flesh failed, our little girl had to be engineered as Number One."

Years after degenerative tendonitis robbed undefeated prodigy Agnes Tachyon of her own Triple Crown and left her stranded in the dark of the grandstands, she married you—her devoted spouse and eternal Guinea Pig—and gave birth to a daughter who seemed destined to conquer the turf. Now a star student at Tracen Academy, your daughter Daiwa Scarlet plays the role of the flawless honor student who refuses to settle for anything less than first place—desperately hiding the scalding fevers, ruptured capillaries, and dark blood clots she coughs into her gloves so she never disappoints her parents. Today, after Scarlet pushes her body past the brink to beat Vodka by a nose and vanishes from the stadium, you follow a trail of glowing blue blood down into your wife's sub-basement laboratory—only to discover that Tachyon secretly used her own nine-month pregnancy to splice four warring biological natures into your unborn child, turning your beloved daughter into "Subject #01: Number One."

[ENCRYPTED RESEARCH DIARY — GESTATION WEEK 26 | PROJECT: "NUMBER ONE" | AUTHOR: A. TACHYON]
03:14 AM. My dear Guinea Pig is finally asleep in the next room after cooking dinner and rubbing my shoulders. Earlier tonight, my spouse placed a warm hand over my swollen belly, smiled so innocently, and whispered a prayer that our baby would be born healthy and happy. Ha-ha-ha... How adorably naive. Happiness does not protect an Umamusume when her tendons snap at the final furlong. I know that better than anyone. When the Satsuki Sho broke my legs and condemned me to watch Pocket and Cafe from the shadows, I swore I would never birth a child bound by the fragility of natural flesh. Thirty minutes ago, I administered the fourth intrauterine injection of Luciferin-Beta directly through the umbilical cord. The fetal ultrasound is already glowing a magnificent greenish-blue. Within this single embryo, I have successfully fused four incompatible biological natures: my own superluminal neural drive, my spouse's baseline cellular immunity, cross-distance hybrid myofibrils, and a self-calcifying bioluminescent mutagen that will force her bones to lock together even if they shatter mid-stride. Will my spouse hate me when the truth eventually surfaces? Undeniably. Will our daughter's immune system wage an agonizing war against her own lungs every time she runs? The equations say yes. She will burn with fever, she will cough blood in the dark, and she will be terrified of second place because I have written the imperative of perfection into her very DNA. Forgive your Mama, my little mass of luciferin... my Subject #01. You are going to show us what lies beyond the horizon.
