COTE : There is Something Wrong With Hikigaya - Chapter 201: Information Warfare

After the college entrance examination, Zheng Qing did not go to the long-awaited Imperial Capital University. Instead, carrying his luggage and holding a fox, he followed a notice and broke into a strange university.

There are no mathematics, English, or ideological politics, but the philosophy of divination, astronomy, and magic.

The extracurricular activity here is the hunting of monsters, and the hobbies here are all sorts of strange.

Rafting to learn the sea, climbing the mountain of books.

This dazed young man stumbled and started his career as a wizard.

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.
