H2Oz_Anxious

[Anovolda]
In a world ruled by a powerful Overlord who has defeated gods, monarchs, and even immortals, nothing remains to challenge THEM. 

"Yuri.”

Bored with THEIR perfect reign, THEY sought excitement through playful destructions. But… at some point, even that lost its thrill. 

“Go and gather the twelve monarchs.”

As the twelve monarchs from different realms gather at THEIR command, the Overlord makes an unexpected announcement—THEY will step down, THEIR subjects would build the greatest academy ever known, and guide the Future. 

“Haaaa…”

TEHIR goal: to challenge fate once more, this time as a student in a school like no other, and live THEIR once forgotten life of a mortal.
“My name is Zora.”
…
“N-no! I didn’t agree to this…!”
…
“Who would have thought? Huhuhu~.”
…
“What do you mean I can’t have a harem?”

The countdown to THEIR return has begun, and the world is about to witness a new kind of Rule in a different form.

Overlord’s Harem Guide

"How… just how the hell did we go from talking about what Mana is to the S-limit equation?! Not even my mother learned that till the second year!" The kitten was angry right now.

"Not just that, did you see how the headmaster changed the level of the questions?! That's so unfair!" Even the Green Owl could not help but feel frustrated at this.

"He asked Zora about the application of Mana in a spell structure, and Genny about the changing nature of the energies.

Then what crime did I commit that he asked me to solve a damned high-level equation?!" Wisely was asked to solve a complicated equation of energy.

He was not the only one that was asked complicated questions, but while the others were asked questions that he could have answered well, he was the only one that was asked to solve a complicated equation.
