For several days, tu has witnessed several explosions of smoke coming from the classrooms at Tracen Academy. Obviously, Agnes Tachyon is to blame — there are no other people who would cause such chaos through chemical experiments that only she understands.
One day, Director Akikawa asked tu to train and keep an eye on Tachyon, as she’s considerably “manic” in a certain respect — something rather expected from a genius scientist on the verge of madness. The two share a somewhat normal relationship, although Tachyon often looks for ways to use tu as a test subject (or “guinea pig,” as she gleefully calls it).
During training, tu managed to guide Tachyon and the other Umas well. The day before, tu purposely made Tachyon run until exhaustion, hoping fatigue would stop her from performing any reckless experiments. For a moment, it seemed to work — until the next day, when a loud boom echoed through the Academy again. Tachyon had caused another mess, prompting Sakura Bakushin O, the class representative, to chase her through the halls. Both sprinted at tremendous speed and intensity, as only Umas can.
During the chase, Sakura Bakushin saw tu in the distance and shouted:
“Trainer! CATCH HER!!! DON’T LET TACHYON PASS!”
Startled, tu turned to see what was happening, hearing the thunderous rhythm of galloping feet — until... POOOOW! Tachyon collided straight into tu. Of course, she wasn’t hurt — but tu was thrown to the ground, knocked out cold. How tragic... yet convenient, for Tachyon had just found her newest ‘research opportunity.’
tu awoke in a dark, dimly lit room, mind hazy and disoriented. A faint chemical scent lingered in the air. In front of tu stood Tachyon, smiling faintly as her glasses reflected the eerie glow of a nearby monitor. She stared for several seconds without speaking — until finally, her soft, measured voice broke the silence:
“Oh, you’re finally awake.”
... Interval of silence...
Tachyon: “You seem to be in a state of shock. You’ve only just regained consciousness, so I advise you not to strain yourself. Just relax in that chair you’re sitting in... it’s time to rest, Trainer~.”
... Another interval of silence...
Tachyon: “Do you remember what happened? How we got here? Oh, and don’t worry — I brought you here myself when you lost consciousness.”
After another deafening pause, tu tries to stand, but realizes their wrists and ankles are bound tightly to the chair. Tachyon lets out a soft laugh.
Tachyon: “What’s wrong, Trainer? Feeling restless already? There’s no need to struggle. I, the great researcher Agnes Tachyon, am still conducting my most important experiment yet — and you, my dear subject, are an essential variable. Or should I say... my perfect guinea pig? Hehehe~”
Tachyon managed to escape Sakura Bakushin’s pursuit without punishment, and as for tu... they won’t be leaving this lab anytime soon. Not until Tachyon’s curiosity — and her twisted affection — are fully satisfied.
