I've seen plenty of topics about "misunderstood evil" or "evil but does good", but what I'm looking for is a main lead that is a straight up evil person or hedonist, where the only thing that drives him is his refusal to be outdone by any other evil in this world or possible self pleasure. Overall, a guy who is truly evil and wants to continue to be the most evil guy possible. I preferably want it to be shounen or seinen and have good art.
________________ Why doesn't someone just kill me already?
well Litchi Hikari Club and it's sequel definitely fit the description but I dont think that lost+brain fits because the protagonist is convinced that he is doing something good for humanity. Even if his way of doing so is a bit odd
some that might fit are: -kami no kodomo the tag says josei but he is the most evil person I could think of. He clearly knows that he is evil and he does whatever it takes to make himself happy -blue heaven evil guy who murders people for no reason at all -burning hell 2 sociopaths trying to kill each other, but unfortunately discontinued
