The Extra's Dimensional Library - Chapter 94: New Rune

This stands at the forefront of strategy guides to Life (a shitty video game)!

Sanctora has known peace for generations—too long, perhaps.Built upon ancient ideals and ruled by a council bound to tradition, the kingdom believes itself untouchable. But beyond its tranquil borders, something has awakened. Whispers of vanished heroes, creatures long thought extinct, and shadows that no longer sleep begin to creep back into the land.Liora never wanted to be a hero. Orphaned young and shaped by loss, all she’s ever known is survival base on love and kindness. But when a brutal invasion exposes the kingdom’s deepest vulnerability, she’s thrust into the heart of a battle far greater than herself. Her light-element magic—once dismissed as minor and passive—may be the key to a new era of power.As Sanctora struggles to adapt, Liora must decide whether to follow the path laid out by those before her… or blaze a new one through fire, blood, and truth.Epic, emotional, and filled with slow-burning revelations, Ancient Beast Summoner is a story of legacy, buried power, and the girl who just might change everything.

I was reborn as the villainous daughter, Yumiela Dolknes, in the world of an otome RPG game. Yumiela only had a small role in the original story, but after defeating the Demon King, she will appear as the Hidden Boss with a bonus specs to solo fight the Hero party.

Having a gamer-spirit, I’ve been raising my level since I was a child. By the time I enter the academy where the game stage is, I was level 99.

I wanted the heroine and the capture targets to defeat the Demon King, but they just flirted around and didn’t raise their level. Moreover, they treat me as if I’m the Demon King just because I have dark hair and use dark magic.

It’s a story where I aim for peaceful days.

Imagine being forced to live, after death, as incorporeal bodies trapped in a vast space of nothingness for thousands of years, with nothing to do but exchanging past memories with other cohabitants (read: weirdos). Everybody wanted out, but there was no way to leave the Void…

Until one day, a young man was finally summoned, as a powerful but reluctant mentor, by a bubbly and motivated but completely naive young girl. Baiyi, finally out of the Void, was the only one who could save all of the other 32 souls from their prison and his summoner might just be The Key to their freedom.

However, Baiyi had to use the techniques and abilities the other souls had taught him throughout the years, and together with his own extensive knowledge of anime and game tropes from his shady and dangerous past as an otaku, to face the biggest challenge of them all: training the clumsy young girl he was forced to partner up with… into a competent sorcerer!

This is a story of heroic adventures, cunning strategies and romantic tales. How will our MC thrive in a world completely strange to him? Where will his ambitions and abilities take him in the palace?
