Naraku from inuyasha, incredibly manipulative and has no qualms uses his own minions to play games with inuyasha, sango, sesshorama,etc in his ultimate goal to acquire the shinkon jewel(which has sentience), which ironically is playing games on the inuyasha-universe, both humans, hybrids and demons alike. strangely he has no animosity against humans, only when it convenient for him to use them as bait for the main atagonists. his mind games often leads to death of his the demons/humans he uses, so it doesnt come back and bite him later in the series.
