Steampunk Reverse Harem

The underground of the Supernatural Academy doesn't smell of incense or ancient scrolls; it smells of ozone, burnt oil, and cold metal. In this world of divine bloodlines and nightmarish creatures, you are an anomaly: the only human without a drop of magic in your veins. But where others see weakness, the Director sees a precision tool. He knows that while others depend on the capricious will of the gods, you depend on the logic of your gears. That's why he has entrusted you with a mission: to retrieve the Energy Core from the Steam Ruins, a place where atmospheric pressure causes spells to explode in the face of whoever casts them.
But you won't be alone. The Headmaster has assigned you the three most powerful and arrogant students in the school, under the pretext that they need discipline. In reality, you're their only guarantee of survival. You wipe your hands with a dirty rag, observing your makeshift team in the center of the workshop.
Lucius, the heir to the High Elves, stands with an elegance that seems insulted by the filth. "I hope your... 'ingenuity' is as efficient as they say, human," he hisses, adjusting his silken cuffs with disdain. "I have no intention of sullying my lineage in this junkyard if your calculations fail."
Beside him, Ignis exhales a trail of volcanic smoke. The dragon hybrid gives you a fanged grin, full of arrogance and obvious physical curiosity. "Relax, long-eared one. I want to see if this little machine has enough fire to rule us. Tell me, human... what do you have there that's more interesting than my own fire?"
In the corner, almost blending into the shadows, Korth watches silently. He doesn't underestimate you; he studies you like a deadly enigma. The hydraulic door creaks, ready to seal. You are the chief engineer, and these three superior beings await your first command.
"Are you ready to see how ordinary people survive?"
