How can I have a heart of a demonic god in my body?! - Chapter 154 - 0151: Ten-thousand-year Blood Soul Flower

In the wake of the Battle of Katze Plains, the banner of Ainz Ooal Gown flies proudly over the city of E-Rantel. The Sorcerous Kingdom has entered the world’s stage to the clamour of death and devastation; the surrounding nations fearfully prepare even as they reel from its calamitous debut. Within the borders of the newly annexed realm, its Human subjects cower in their homes as the Undead openly walk the streets and stalk the lands. Yet, when a destitute noble finds herself under the auspices of an unlikely benefactor, events are set into motion that will resound over the world for ages to come.A kingdom builder based on the events and setting of Kugane Maruyama’s Overlord. In a fantasy world where beings of matchless power are transmigrated from the arbitrary existence of a game, Valkyrie’s Shadow chronicles the lives of the natives whose reality has been turned upside down by their advent. It is the tale of a nation created by the whims of a supreme sovereign, and his unstoppable servants who each have their own, often twisted, interpretations of their Master’s Will. There is no victory in strength; no miracles wrought from magic that will save them: only the inexorable advance of a new world order where those who secure a place of service within will find themselves turned against the world that they once knew.[Slow buildup. Methodical storytelling with a focus on well-rounded kingdom building and character development.]

A perfect exercise has created a mythology academy that makes the heavens and the world tremble.

The invincible dean leads a group of teachers and students who are not afraid of the sky and earth to compose a myth together!

When hundreds of millions of years have passed and he is no longer in the world, there is one title that still makes the world tremble: Dean!

- Description from novelbuddy

Waking up as the most hated noble family in a fantasy world is bad. Inheriting a 50,000 gold debt with a death sentence attached is worse.​But the Sanusi family isn't scared. They are from Earth, and they brought the Industrial Revolution with them.​Now, the magical realm faces a new kind of warfare.Knights vs. Tanks.Mages vs. Railguns.“You have a Dragon? That’s cute. We have Anti-Air Cannons.”​It’s time to pay debts and conquer kingdoms.

I died in my world… and woke up in someone else’s story.But not as the hero. Not as the villain. Not even as a side character who mattered. I’m… an NPC—a nobody, a background observer, invisible to everyone.At first, I thought I was powerless. But then I discovered something strange: I could leave notes, whisper hints, move objects… small nudges that subtly changed the story. Every tiny action rippled through the plot, shaping outcomes, saving lives, and altering the fate of heroines, heroes, and even villains.The catch? The story is alive. It resists interference. Push too hard, and accidents happen. Plot twists turn against me. Minor disasters loom. The more I try to influence, the more the story fights back.So I play carefully. I study. I manipulate quietly. I watch the heroines, heroes, and overlooked side characters, weaving invisible threads that guide them. I don’t fight. I don’t cheat. I survive—and maybe, just maybe, I can change the story from the shadows.From an unnoticed NPC to the hidden hand behind the world, I’ll prove that even a nobody can rewrite the story.
