One Piece: Marine to Warlord to Conqueror - Chapter 114

I’ve become a rogue lord in another world! This is the story of a game I was playing! The story of the protagonist, who has become a rogue lord who dies after two days, successfully uses the game’s history and system to escape his impending doom and become the strongest.

In a mind-blowing twist, I found myself reborn into a steampunk-themed JRPG made by a Japanese game company. To my shock, I was appointed as an executive of the villainous faction. However, the protagonist’s party was way too diligent.

A tale of urban demons and spirits, the mysterious exorcist and I.

Do you believe that supernatural creatures exist in this world?

I’m an ordinary college student while he’s the handsome and powerful demon exorcist from the mysterious old manor.

Our paths had never crossed before and yet, our fates became intimately entangled after one chance meeting.

The knocking on the coffin in the dead of the night, the little girl weeping inside the box-shaped structure, the good friend of mine who was cursed…

Together, the mysterious exorcist Mr. Wen and I embarked on a path into the world of the grotesque and motley.

Gradually, I realized that I had developed special feelings for him that went beyond friendship…

But, the problem is I’m a man!
