Since the opening of the Dungeon Rifts-- also called D.Rifts or Drift Dimensions, the world has changed. It's become more militaristic and violent-- unpredictable, even. Monsters raze cities and bring diseases that birth new races. Magic exists in a constant state of hyperflux, birthing new powers and changing the functions of old ones.But none of that mattered for Rex. He wasn't a Drift Soldier-- as much as he wanted to be. He didn't have powers-- even if he wished he did, so when he graduated primary school, he expected to get his Drift Armament and find a bit of consistency for once in his life.But you know what they say about expectations......DING![Congratulations! You have awakened the Beast-Totem and unlocked your Werepanther System.][5 Totems Remaining....]*********Extra tags: kingdom building, military, martial arts, overpowered, scifi-fantasy, post-apocalyptic, factions,

When the enigmatic and overpowered Kieran Drayke awakens in a foreign magical world after a sudden transmigration, he brings along a system unlike any this realm has ever known. The “Sovereign Architect System” doesn’t just make him invincible—it gives him the tools to build something far greater.But Kieran isn’t interested in world domination. At least, not in the usual way.Disillusioned by the world's surface-level glimmer and the rot beneath it, Kieran sets his sights on the forsaken—those discarded by society, lost in the shadows of nobility and corruption. From slums, war zones, and forgotten ruins, he gathers orphan girls of various races—elves, beastkin, humans, and more—each with untapped potential and pain behind their eyes.He trains them in secret. Guides them. Empowers them. Not as soldiers, but as a family. A hidden organization that operates behind the curtains, shaping the world while appearing as ordinary students at the prestigious Aetherion Magic Academy.Kieran himself? Just a carefree, slightly lazy transfer student with a penchant for sweets, sarcasm, and sneaking naps between classes—on the surface, at least.With a slow-burning plot that weaves magical worldbuilding, deep friendships, training arcs, casual comedy, and a cast of unforgettable girls who grow into queens of the unseen, Chronicles of the Hidden Crown explores what happens when an OP MC doesn’t conquer the world with brute force…But builds a legacy from its forgotten pieces.No betrayal. No forced drama. Just the steady rise of a secret kingdom in the shadows of a crumbling empire.

Yang Gang accidentally became the imposter heir to a wealthy family, with a beautiful older sister and a twin younger sister at home...
