A Certain Scientific Kamen Rider

How long does it take to handcraft a fully functional transformation belt in Academy City? For Mo Wang, the answer is three years. As a Level 3 overall enhancer, his ability is far from extraordinary—but it is enough for a transmigrator to survive in this city of science as a researcher. He sold patents in materials science, spent two years on foundational AIM field research, and filed patents for carbon-based cell culture techniques. Every penny and every ounce of effort went toward a single goal: building a Kamen Rider system from scratch, so that he could survive the chaotic battles yet to come. A sound module was a must—transforming without one would lack style. A biometric lock was non-negotiable—what if he lost it? Separation from the user for over a minute? Self-destruct. Perfectly logical. As for why Last Order insists on calling him "Daddy"... all he said was, "Your body incorporates my technology, so in a sense, I am your father." He never expected her to take it literally. ..."Little Mikoto, tell me—is it normal for a scientist to fall in love with his own creation?"
