recsss!

Bungou stray dogs and Balance unlimited
And there's an anime movie called 'The empire of corpses' these gives pretty similar vibes
Also if you're looking for someone who kills the bad guys like liam does maybe try Brutal satsujin

I was actually thinking of reading brutal satsujin, also I’ve watched balance unlimited and watched bungou stray dogs but it’d not hurt to read the manga as well, thank you so much for the recs!
