Somehow he was an adventurer before dying despite not being able to communicate well with people, especially women. Okay, but he spends the entire first arc looking for someone who's willing to talk to him, and when he finally finds one, he sprints away at full speed. Because she's naked.

One of the minibosses/enemies is described as a monstrously ugly transgender women, though her appearance is clearly supposed to be a caricature of a drag queen. She also kidnaps and sexually assaults men. Since the scene is supposed to be comedic, there's significantly more emphasis on her being monstrous because she's ugly, rather than because she, yknow... kidnaps and assaults people. Transgender people already get a bad reputation without continuing the "Haha, transgender people and crossdressers are predators!" s*upidity.

He can't talk to women, he wants to die.

The main character revives as an incredibly powerful undead but simply wants to die. In 51 chapters he has excessively limited interaction with any of the other 'developed' characters beyond simply trying to avoid them. He's faced two serious foes so far, an undead organisation and a dragon - both of which he dispatched with little effort. His confrontation with the King in 'battle' had the potential to be interesting, but it was brief and didn't lead to much. The much anticipated confrontation with the holy woman who has been chasing the main character has finally happened in chapter 52 - it mostly skipped over it, only showing the beginning and end of the conversation, feels like a missed opportunity to have some interesting dialogue.

The main character's quest to die is difficult to sympathise with. He has no reason to want to pass on other than 'man, it should've happened already, I really want to go'. There's no inner conflict, he's resolute without reason. If he gets someone to care about and then has some kind of crisis about whether he wants to go - that'd make his character a little interesting, but there's no sign of that happening so far.

I hope he meets an enemy he can't just defeat in one punch soon - I'd like him to make full use of his regeneration ability and outlast his opponent. I also hope he learns to actually care about something other than dying so he has something real to fight for.

on one hand he has no problem killing a sentient dragon, that can talk and act exactly like humans, that just came to save a dragon that the humans kidnapped, while on the other hand he wont even kill a group of bandits that just killed the guards of some merchants and were about to r*pe their wives and daughters.

A few people already realize he’s not an enemy like the Thunder Dragon Emperor he saved from the dragon attack, the girl who’s following him which is also helping to purify him, some villagers and kids he saved from monster attacks, and a few others. Unfortunately his reputation to the public is still bad because of a certain psycho who told them the “No Life King” has returned and he will create an empire with undead and rule the world or something.

He has the ability to resurrect others and so far he has 2 powerful dragons (busty and loli (?) with a 3rd otw, and an Empress.

The worst part is in chapter 11 where the adventurers are all collapsed right in front of the MC, waiting for him to kill them. They all heard what he said -- "won't kill you" -- but instead of realising that he might not be out to get them, they immediately assume he wants to torture them or track them down later and kill them then. Equally silly is that despite this perfect opportunity to talk to them, the MC suddenly decides that he doesn't want to explain himself anymore... obviously because the author isn't done milking this forced misunderstanding. He just heads off and lets the problem fester. Really?

Frankly speaking, something has to be wrong with you if you like this garbage -_-
