A solid list. I guess I also have an interest towards novels with twisted characters XD

Came here from Negary page. Got interested in call and bloodcore.

Apartment for rent is one of novels on nu which left me with the strongest impression. Tutorial is good though I got bored at some point of time. Loved arc about drinking Paramal.

I have seen circus long ago but taking into account amount of translated chapters as well as translation speed interest towards it starts to wane. I have a hunch it’s one of those stories you would rather read whole than reading a chapter after a month of waiting time.

Tales of herding gods starts off amazing though it loses its extraordinarity midway. Point is despite it being correct your description doesn’t waft off allure. Maybe you should consider changing it, making stress on the premise of the world, pointing out about great ruins, what night comes with and shadows of the past

Read immortal sword master by get lost

Great novel as well 

Altough translation has stopped you can read it in mtl novel

I recommend Sss-class su*cide hunter. The first few chapters personally shocked me in how the MC would do anything just to reach his own goals.

Plauge Doctor is also good too. 

Astral pet store

The mc at chapter one was sane

After chapter 1 he becomes kinda insane, he still has reason in him

About 200 or 300 chapters in he becomes full-blown crazy and starts mu*dering anyone that goes against him even if he is in the wrong while making poor and unreasonable excuses

Spoiler:

There was a guy that wanted to kill him after the banquet(it is banquet that was made for their profession, pet store or carer or something). He was pointed out why the mc is wearing casual clothes and that the mc is being disrespectful. The mc becomes even more disrespectful which made the leader of the banquet angry. The leader wanted him out and the mc responds by killing the guy, who wanted to kill him. This enrages the leader who orders guards against the mc, which the mc slaughters. The mc makes up an excuse as to why he did this; The mc started killing because they were being disrespectful to him, even though they only did that because the mc was very disrespectful.
