Recommendations Assassin that behaves like an assassin

So, I'm looking for novels in which the MC is behaving like a proper assassin instead of being a warrior, a general, a schemer, a tactician, or Naruto. I want the MC to suck it up when he was humiliated during the day and to kill his enemy when they sleep at night. I want a cowardly MC that bribes waiters and maids and poisons his enemy. I want a cruel MC that kills his enemy when they reach orgasm when they f*ck and kills the women too just to get rid of the eyewitnesses. Using a disguise and tricking the witness to mislead the suspicion and shift the blame is also fine too. I want a ruthless MC that would even go as far as hiding in a latrine and stab his enemy's asshole when they shit.

Jun Mo Xie from Otherworldly Evil Monarch barely makes it. I like how he hid in the shadows and kill his wounded enemies that lying on the beds and how he killed his ambushing enemies silently with one stabs in their hearts from behind. What putting me off is :

He waited for his enemy to say few farewell words, to grieve upon his brother's death, to achieve a breakthrough, and THEN continue the fight. What I want is the MC who will stab him when his enemy is hugging his dying brother, I mean : IT'S A CHANCE!

Edit : at the very least, I want the MC to not wasting time in killing his enemy, meet-stab-kill-leave.

 

Death Scripture

 

Night Ranger - He's ranger but behaves like assassin
Abyss Domination - The owner trying to kidnap his sister in the inn while he go out, then he assassinate him and his people in the night with dagger coated in poison, then burn the inn to ashes.

 

Death Sutra

 

Akugyaku no Black Maria

 

It's rare to find stuff like this. It's kinda annoying when you have an 'assassin' MC who tries to assassinate someone, then when it fails (inevitably), they just... straight out fight? What? What kind of assassin just fights their target straight on? May as well be a sellsword.

Anime version- I’ve seen... if you don’t dislike “older” (a little) style animation - good stuff

Hidden Assassin

 

Farseer trilogy.

 

To Be a Power in the Shadows perhaps?

 

Ok this one isn't an assasin, but he is a Mad cientist, total villain potential, heck I am sure that Hydra would pay high penny to hire this guy, he is ruthless. Ouroboros Record ~Circus of Oubeniel~. Is JP but what has been translated has just showed that he will kill anything that guets in his way or even worse use it as a test subject for his research into inmortality.

 

Death Sutra - but he is sometime fight with the enemies.
Assassins Chronicle - I think this one kinda similar with your taste

 

=> then MC assassinate him and... ?
What happened to MC's sister ? It's highly probable and hope that she is safe.

 

Will try Death Sutra (I wonder how did I miss it).
As for Assassins Chronicle, is that an assassin? More like a magic-swordsman, riding unicorn with holy flames.

Gonna look for it.

I dropped Night Ranger a long time ago for reasons that I forgot. I'll re-read it for a while, looking for the reasons of why I dropped in the first place. As for Abyss Domination, the release rates is worrying.

The releases is worrying me. I don't want to die from hanging from a cliff.

More like Gigolo-13 lol. I read the manga.

Manga? Will try it.

MC is not an assassin, he's a warrior. What he's hidding is not his presence, but his identity. He fought frontally, not "from the shadows".

Spoiler

Merciful enough to deal enemies quick deaths, but ruthless enough to consider murdering a maid (that served his mother for years) to seal a secret. Careless enough to slip clues, but clever enough to cover up. Limits his own strength and strives for a peaceful life... ridding himself of anything or anyone that'd get in the way (barring a few subordinates he trusts). Uses what's available to him. The more practical, the better...

This might be close to what you're looking for.

 

It's not. The Lazy Swordmaster is just crappy slice of life shit that gets incredibly boring and real fast. At least for me. Also, the times where he acts "assassin"-like are really few in number. Granted, I only read about 50chps of it and I don't particularly like slice of life that much, so I'm biased.

 

Never know unless you try.

 

It's just that you totally focused your description of the novel to the rare parts where he acts like the OP requested mcs to act like.
