Villainess's Suicidal Butler [Dark Fantasy based LitRPG]

[This series draws its complete inspiration from Dark Souls and Lovecraftian Horror.]

In the immersive world of the highly popular heroine game "Devourer IIX" where players navigate the complex dynamics of a fantastical realm filled with powerful heroines and heroes, one loser named Leon finds solace in his obsession with the villainess, Celestia Draven Dreadborne. Little does he know that his virtual infatuation is about to become a reality beyond his wildest dreams or nightmares.

After a forceful entry by killing his friend, he is inexplicably transported into the game world, but with an unusual system and a role of a butler for the villainess.

Will he emerge as the savior of Celestial Conquest, or will the game's intricate web of alliances and betrayals consume him?
