Any good shounen where the mc is actually a cold-hearted person (not necessary) and kills the enemies without giving them a single chance or feeling bad abt it, long story short, a merciless mc, no romance pls
try "from the red fog", if u havent
This one is my favourite: https://www.mangago.me/read-manga/chronicles_of_the_demon_faction/
