I Play Yu-Gi-Oh! Card Game - Chapter 124: Heroes can never back Down

Kael, a former professional player of “Netherworld’s Gate” club, crossed into the game before it launched and became a Mixed-Blood Succubus. However, Kael always felt there was something not quite right about the way he raised the Fourth Calamity(player) as leeks for harvesting. Other NPCs’ methods of reaping players’ leeks: Unfathomable strength, top-tier plot backgrounds, hidden stories, and various skill teaching methods. His own method of reaping players’ leeks: An innocent yet desirable face, a small pink tail, eyes emitting hearts, skills with off-the-charts glamor… along with a turn-back-and-smile from the game’s promotional video. Wait a second, did I get something wrong with my great adventure in the game world? This book is also known as: “Succubus Reincarnation: Show Your True Skills in The Game World”, “The Common Succubus’s Cultivation Method”, “My Succubus Growth Monogatari is Surely Problematic”!!!

Well, life had something else for him despite his wishes.“That… beauty, will there be an increase in wages for conversion from ‘boyfriend’ to ‘husband’?”

Sam Sanderson is envied by many for his job, however he himself didn't seem to like it much.

Due to his expertise in nanotechnology he was tasked with monitoring the state the Valkyries, humanity's strongest weapons who all just happen to be made into gorgeous females.

Forbidden from even touching any of them, Sam spends his days in agony watching flowers he couldn't hope to touch. However one day all of that seemed to change.
