Magical Mechanoid Almunale

Eldo is a boy who loves operating machinery and has been reborn while retaining memories from his previous life in Japan. He had been living a life far removed from machines in a farming village on the frontier. One day, while hunting as usual with magic, he accidentally discovers a broken humanoid robot called "Aluminare" that no longer functions. In a world he thought was a sword-and-magic fantasy, he finds a material that perfectly brings out his hobbies. Eldo's heart races with excitement, and he begins taking action, dreaming of becoming its pilot. All three volumes are currently available from MF Books.
