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.
