Naneun Skeleton-eul Kiunda

A necromancer is a profession considered the noble of nobles, with less than 1,000 in the population worldwide! I was born with a diamond spoon, no, a necromancer spoon in my mouth! ...Or so I thought. *"I'm just a defective necromancer."* \[Using skill, "Summon Ordinary Skeleton" (E-rank).\] You'd think a necromancer should be able to summon liches, Dullahans, or death knights. But nope, I can only summon skeletons. But then one day, suddenly... \[Hidden condition achieved!\] \[Condition: The 10,000 Uses Rule\] \[Your rank has upgraded to D-rank!\] I achieved the hidden condition and gained the ability to raise my skeletons. From E-rank to S-rank! The story of Joo Donghoon unfolds, the world's only cursed necromancer, who's speeding toward becoming a ranker! (Source: KakaoPage, translated)
