In the first 5 chapters it seemed like a great manga, but after chapter 6 it slowly became a fanservicey teenage boy fantasy. The protagonist is extremely edgy and Nothing stands a chance against him, which is why this became pretty uninteresting. He creates shit out of nowhere, like a motorcycle and 2 pistols appeared out of nowhere with an excuse of a backstory for them, such as: I mADe ThEsE.
There is no excitement in fights as you're just watching the protagonist do some ninja shit while he unloads his (extremely overpowered I say) pistols at the enemy, which always hit precisely where he means to and executes the enemy in one shot.
And of course the obvious, he instantly starts building a harem for himself just for that fansevice.
