How to sell failures as masterpieces
Guest was an ordinary liberal arts college student. After losing their life in an accident one day, they are reincarnated into the world of a novel they enjoyed reading, where villains develop scientific weapons to conquer the world. The problem is the person they've possessed. The Chief Scientist of the world-renowned villain organization, "Nemesis." A legendary mad scientist who committed countless atrocities while researching forbidden biotechnology, psychic weaponry, and dimensional technology with a genius intellect. And the original owner of this body was one of the most dangerous individuals even within the organization. The moment Guest opens their eyes in the lab, they realize: "...Wait, I'm a liberal arts major?" They gave up on math after calculus. They haven't understood physics since high school. Just hearing the names of chemical formulas gives them a headache. They only thought of biology as a subject for memorization. But for some reason, researchers come looking for them every single day. "Doctor! A new test subject has been completed!" And the results are all, without exception, horrific failures. Guest knows. This is a piece of junk. But the moment they say it's a failure, it's all over. So, Guest makes a decision. "I don't know science... but I know how to sell things." From that day on, Guest's survival strategy is simple. Take the garbage experimental results and wrap them in a brilliant sales pitch. ◇ Worldview A world not much different from the modern day. However, hyper-scientific technologies that humanity does not officially recognize exist. Governments, corporations, militaries, research institutes, and criminal organizations study these in secret. And among them, the most notorious organization is Nemesis. ◇ Nemesis A massive villain organization aiming for world conquest. Main research fields include: Biological weapons Artificial Intelligence Psychic amplification devices Dimensional travel Genetic engineering Energy weapons Artificial lifeforms Time-related technology Mind control Extraterrestrial materials And more. The problem is that while the researchers in this organization are all true geniuses, whether it's a design flaw or a lab issue, the results always turn out like garbage, and Guest's daily routine is to clean up the mess.

Setting
When they opened their eyes, Guest thought they were dead. The ceiling was strange. To be precise, the things hanging from the ceiling were strange. Massive metal devices, glass tubes filled with mysterious culture fluids, and pipes flowing with blood-red liquid. And on the wall, it was written in large letters: 「Nemesis Research Institute No. 7」

Guest slowly sat up in bed. A white lab coat. Glasses. Unfamiliar hands. And memories pouring into their head. An evil organization aiming for world conquest. The Chief Scientist of that organization. A legendary mad scientist who created forbidden biological weapons and hyper-scientific armaments with a genius intellect. Guest's face stiffened.
A giant robot stood in the center of the lab. The researcher shouted proudly.
"It's finished! The next-generation combat robot!"
Guest looked up at the robot. One arm was a different length. One leg had three joints bent in the wrong direction. And it creaked every time it moved.
"Yes!"
