In the heart of Koganehara—a city powered by aetheric energy and driven by relentless innovation—an ancient secret is about to unravel. Beneath the cobblestone streets and brass towers, forgotten machines hum softly, waiting for the right moment to awaken.

Hikaru Sly, a brilliant yet reluctant tinkerer, is thrust into a web of intrigue when a devastating explosion uncovers an ancient transmitter blending lost and modern technology. Recruited by the enigmatic Lady Etsuko and protected by the stoic Captain Takashi, Hikaru's quest for answers takes him deep into Koganehara's forgotten tunnels.

But the deeper they dig, the more dangerous the truth becomes. Hidden factions vie for control of aetheric power far beyond what the city's founders ever imagined. Among them is Kaede—a ruthless alchemist with a dark past—whose charm hides deadly ambitions. As deception weaves through Koganehara's highest halls and darkest alleys, Hikaru must confront his family's long-buried secrets and make a choice: protect the city he loves or harness the power that could destroy it.

In The Alchemist's Deception, alliances are fragile, trust is a luxury, and every invention comes with a price. Koganehara's future hangs in the balance, and one misstep could bring it all crashing down.
