We Agreed on a Magical Isekai, So Why Are You Piloting a Mecha?

What does it feel like to have a lover who is simultaneously your confidante, maid, soulmate, and emotional sanctuary—someone whose appearance perfectly matches your tastes and can transform into a colossal mecha at any moment? For Tan Po, the answer is simple: it feels absolutely incredible. The continent of Vodeland has always been a mystical crossroads connected to countless other planes of existence. Here, technology and magic shine together in an era of unprecedented prosperity. Yet behind this golden age lies an increasingly bitter conflict between the native royal authorities and invading forces from other realms. Tan Po was just another ordinary transmigrator until the day he accidentally awakened a super artificial intelligence named Aine. By day, she serves as the intelligent core controlling massive constructs, becoming an avatar of destruction that strikes terror into his enemies. By night, she transforms into a beautiful girl with waist-length white hair, acting as his intimate companion by his side. From that day forward, Tan Po walked a path no one had ever taken before. He used computational power to deconstruct magic and machinery to drive production. He ended famine, compiled the very laws of reality, and personally shattered the barriers of innate talent, ensuring that magical power was no longer a privilege reserved for the few. Many years later, seated upon his throne and gazing out over the thriving land he governed, Tan Po could not help but think back to those earliest days.
