The Exiled Alchemist Unknowingly Becomes a Legend – Living Happily in the Frontier with My Yandere Little Sister (the Kingdom’s Guardian Dragon)

World’s Strongest Yandere Little Sister. Anyone Who Hurts My Dear Big Brother, I’ll Personally Drag Them Straight Down to Hell!

“Myce Windsor, I hereby exile you for the crime of high treason against the kingdom!” The protagonist, alchemist Myce, gets sentenced by the king to banishment in the remote frontier. The reason? He’d been secretly visiting the strongest dragon protecting the kingdom—the Guardian Dragon Valitra—and that was judged as plotting against the realm. “As I’ve explained many times before, the Guardian Dragon Valitra that His Majesty worships… is actually an artificial magical beast that I created with my alchemy.” “Hyahaha! Big bro, I never thought you’d tell such a massive lie right here in public! You were born with a dud skill, a defective product. You can’t even make a proper healing potion, you useless piece of trash!?” Even though he told the truth, no one believed him. Instead, his father and younger brother publicly insulted him in front of everyone, and Myce was sent off to the dangerous borderlands. But the truth was, the Guardian Dragon Valitra was actually his little sister, Tinny, who everyone thought had died four years ago. Myce had used his alchemy to evolve her into a dragon to save her life when she was on the brink of death. The reason Myce kept visiting Valitra was to turn his sister back into a human form. “My dear big brother Myce is my savior and the one and only person worthy of ruling over everything in this world—the Supreme and Greatest Being. Anyone who dares to hurt my dear big brother Myce, I, Valitra, will personally drag them down to hell!” The kingdom that earned the wrath of the Guardian Dragon Valitra began walking the path to its own destruction. Meanwhile, the frontier region under Myce's rule experiences unprecedented development thanks to his alchemy, and everyone there lived happily ever after.
