"I don't want to stand out" The mc says as he buys a loli slave and buys expensive items that emit an aura easily noticed for said loli slave.
Also, yet again, a manga gives the mc a gun without understanding anything about guns. He holds the bolt action rifle like a pistol. And shoots it with one hand outstretched like one does for a pistol, which makes scopes essentially unusable, but he still has one on his gun. It acts like a semi-auto gun, which is odd as it has a bolt.
Also, the lack of any gun safety is appalling. He points a gun at a child and shoots them with a "special healing bullet" without knowing what would happen. Literally no proof that it wouldn't kill the kid. And this happens again with "fainting bullets" that he shoots three men with, point blank, after they've done nothing to warrant being shot. Him shooting them point blank execution style is another problem as well. Shooting from that close will cause charring on the skin, which is how police tell if someone was executed from point blank range.
Another thing, when he shoots wolves, they fucking get ripped in half. It looks like the bullets are 7.62 or some other medium caliber bullet, which wouldn't do much more than penetrate and leave a quarter inch hole. Even .50 caliber bullets wouldn't cause that much destruction. (There are videos of people hunting deer and other small/medium game with .50 caliber guns and they really only ruin a bit of meat where the bullet hits, nothing like what is shown in the manga.)
Over all, this boring pile of ass is just terrible in almost every way it tries to be unique
