"I NEED MORE MONEY," I stated to the empty air of my workshop, The amount of materials i need was astronomical.
"I could always go outside... No, no, no, that won't do. Not yet," I mused, pacing a worn circle into the floor. The workshop was a sanctuary, and the outside world, a dangerous variable. "Still, I could get more data if I went out... And I can test the Tachyon Armor Mk 2 to see any bugs or problems."
A decision made, I turned to the two other occupants of the room. Martha and Ruby, "Stay in the room and wait for my return," I commanded.
The moment I stepped out of the subterranean workshop and onto the street, the sun was an immediate, blinding assault. "Ugh, the sun blinds me," I muttered, raising my hand to shield my crimson eyes.
"Anyways, I need to find a willing or not-so-willing guinea pig," I said, a dangerous glint in my eye.
I started with the usual spots: alleyways and dumps. But I only found beggars and the Infected. As I walked, I passed a familiar, abandoned storefront. Weird... I thought, before dismissing it. "Got to find me a guinea pig."
Deeper into the industrial sector, a familiar sound drifted toward me. "Mhm, what's this? Someone getting robbed? Well, it's something, right?"
I headed toward the commotion, but not before I reached into my coat and deployed my Tachyon Device Mk 3. The small, unremarkable cube instantly transformed, unfolding and clicking into a long, sleek, futuristic rifle.

"Good thing I bought this in the system shop, though it can only stun," I mumbled, powering it up. I sighted on the nearest thug, pulled the trigger, and a pulse of cerulean energy slammed into him. He froze mid-swing, eyes wide.
"What!?" one of the other men yelled, spinning around to face me. "You! Get her!"
Five guys with rusty pipes and knives came charging. "Heh, nope." I fired two more rapid shots, and two more went down, spasming in place.
"Die!" one of the remaining thugs screamed, raising a heavy baton. It descended and connected with my shoulder with a sickening thud, but only a dull clang echoed. The Tachyon Armor Mk 2 instantly flared and moved to protect me.
"Heh, the armor responds to physical trauma instantly, absorbing the kinetic energy for me to use," I explained, as much to myself as to the startled thug. My hand was covered in the glowing yellowish armor; I drove a punch into his gut that sent him sailing into a nearby garbage cart. CRASH!
"So, gentlemen, do you want to do this the easy way, or the Gold Ship way?" I asked, looking at the last two who were frozen in fear. They answered by blindly charging.
"Gold Ship way it is," I sighed.
My rifle instantly reconfigured, the barrel collapsing and extending into a vicious-looking Electro-Spear. I lunged, stabbing one of them in the chest. He convulsed violently, his clothes smoking, before he dropped to the ground like a roasted chicken.
"Your turn," I said, turning my head toward the final man. He panicked, trying to scramble away, but you can't outrun an Umamusume. After a short chase, I broke his legs to ensure he wouldn't run and transported them both into my System Inventory.
I then looked at the original victim, who was still trying to process the chaos.
"NO ONE WILL BELIEVE YOU," I whispered, before disappearing with a flicker of my dimensional displacement field.
"The... the fuck was that!?" the victim stammered.
"Okay, I need a room for this..." I thought, heading straight to my apartment building. I quickly located an empty, abandoned room, perfect for my temporary lab.
I put my gear down near a table, then opened my inventory, summoning the remaining seven people I'd captured-taped, gagged, and secured.
"Mhm, what to do... Well then, let's start experimenting, shall we?" I said, a manic, uncalled-for smile stretching across my face. It was a look that terrified five of them instantly.
The sixth subject, however, mumbled, "Mmm! I'm omm-kwith-it!" and gave a muffled, enthusiastic thumbs-up. I heard it clearly.
"Hah! Let the fun begin!" I cackled, grabbing the man and starting the initial examination.
Experiment Log: Terran Biology & stuff
Log Entry: Day 1
"All subjects are Infected, Stage 1 to early Stage 2. Subjects 1 and 2 are dead from initial stress tests. From what I can tell, the biology of the Terran people is much stronger than regular people back on Earth. However, I, as an Umamusume, am on par with them in terms of raw strength. More testing is needed," I dictated into my voice recorder.
Log Entry: Day 3 (Test 5)
"From what I gathered from Subject 3 and 4, they can survive Earth's conventional weaponry. A 12-gauge shotgun round will not do anything to a Terran; best case, you just slow them down.
Log Entry: Day 5 (Test 10)
"Subject 3 is dead. Died from a weapon I purchased with the funds acquired from selling the dead bodies to the System-which, conveniently, provides me with a good chunk of money, only usable within the System shop. The weapon in question: the AR2 from Half-Life 2. More tests needed for weapons that can effectively stop or kill a Terran."
Log Entry: Day 7
"Subjects 4 and 5 mostly killed themselves, but I managed to stop the final blow. I've managed to upgrade all my equipment and bought a Wisdom Cube from Azur Lane. This cube provides a ton of energy. Using it will give me great benefits, but I haven't yet, as I don't know what ship I'm going to get. I bought a random Light Cruiser Class Cube. I could also use it as a reactor..."
Log Entry: Day 10 (Test 25)
"Subject 4 and 6 are dead. The G3 gas I bought works on Terrans, but it's deadly if they stay in it for long periods of time, so a stronger version is needed. While I wasn't looking, Subject 4 grabbed a scalp and stabbed himself; the others called him 'lucky.' Too bad, lost data, but I still have two left. I have something special for them."
Log Entry: Day 11 (Test 26 - Final Test)
"I have enough money now to buy all the materials and stuff I need to upgrade my current equipment and create new gear. Now, for this last experiment, I have purchased a Medi Gun from the shop. I will test how the Medi Gun can heal a person without a leg, arm, or internal organs. If one of them survives, Test 27 will be very interesting."
Log Entry: Day 12 (Test 27 - Success!)
"Subject 3 is dead. Too bad; I guess the Medi Gun can't heal you if your brain and multiple organs are gone, though I do have a ton of organs I can't sell to the System. Subject 7 will become different after Test 27. I bought a random Destroyer Class Wisdom Cube. The cube did work! Now, the subject is a woman and is completely loyal to me, thanks to a system modifier I applied. The ship she got is a Z23 Destroyer Class. Further loyalty testing and combat trials will commence."
Log Entry: Day 12, Later
"Subject 7 is a huge success. Her loyalty is good enough for me to trust her, and she can use her rigging anywhere, which is a great combat advantage. I have made her clean the apartment as I need to return back to Martha and Ruby. I have been here for 12 days. I will update when I return."
I finally returned to my actual apartment, only to be immediately confronted by the owner.
"Hey, you! Where's my money?" he demanded, eyes narrow.
"You'll get your money when you fix this damn door!" I shot back, pointing at the shattered, unable-to-be-locked door.
"Grrr, fine! I will deduct payment for the broken door, but the rest you pay now," he grumbled. I gave him the money, which he snatched before promptly leaving.
Before I could breathe a sigh of relief, Martha was in my face. Her voice was sharp with indignation. "Wait, is that why you made us stay? And wait, where were you? You have been gone for twelve days! Do you have an explanation?"
"And who's that?" she said, pointing her hand at the newly transformed Subject 7.

"I am Sub-" the woman started, but I cut her off instantly with a fierce stare. My crimson eyes bore into her until she stammered into silence.
"She's a colleague of mine, right?" I said, switching back to my normal, goofy self.
"Ah, yes! I am her Colleague! Nice to meet you," Subject 7 said nervously, taking the hint.
"I am Martha, and this is Ruby. It's nice to meet you, but, Miss Colleague, you and I will have a talk," Martha said, her voice dropping a register.
"She's just like Super Creek," I muttered, chuckling nervously.
"I am in danger," I muttered under my breath.
"You said something?" Martha asked.
"Nope."
