Tech Hero in Another World Novel

Ren Takamura is an alien child born during a catastrophic conflict on another world. Sent to Earth as an infant to ensure his survival, he possesses extraordinary intelligence and the ability to manufacture technology from any material he touches. Discovered by a rural Japanese couple, he was raised as an ordinary human. Despite his remarkable abilities, living in a peaceful environment required him to suppress his true nature. Growing up, Ren developed a passion for high-tech superheroes and harbored dreams of becoming a hero himself, yet circumstances never allowed him to pursue this ambition. Everything transformed when Ren and his classmates were suddenly transported to a parallel world consumed by monsters, warfare, and destruction. Witnessing the desperation and vulnerability of that world's inhabitants, Ren finally saw his opportunity. Rather than relying on magic, swords, or conventional strength, he would become a hero through technological innovation that exceeded any known civilization's capabilities.
