William and his college class are ripped from Earth and thrown into Aethel, a world on the brink of collapse. Everyone gains incredible magical powers – except William. Mocked and underestimated, he’s an outcast among heroes. But William has a secret: an SSS-ranked skill that lets him travel to Aethel’s past. Learning lost magic from ancient masters, he’ll surpass his classmates and become the true savior Aethel needs. But can he overcome the dangers of the past and present to forge his own destiny? While others studied about the first mage, William could go back in time and see the first mage himself! While others dreamed of seeing a dragon, William could go back in time, hatch a legendary dragon egg and turn it into his puppy. While others used common materials to craft their items, William could go back in time and mine materials that weren’t find anywhere in Aethel anymore. Is it unfair? Perhaps, but William was not the type of person to not use the powers the universe gave him.

While the demons were rising, mankind was about to become extinct. Six temples rose and protected the last territory of mankind.

A young boy joins the temple as a knight to save his mother. During his journey full of miracles and tricks in the world where temples and demons are antagonistic to each other, will he be able to ascend to the strongest knight and inherit the sealed divine throne?

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.]

Note:
