not gonna lie, it got me a chuckle too, it's like the first sensible thing it happens in a really long time, like why wouldn't he have a gun, although now the question is how author is gonna bs this, also with the explosion the gun should have gotten damage if he had it with him at that moment.
No no no no no.
You don't give this hack credit for that, no. That was as ridiculous as the rest of the chapter was. Because where THE FUCK did he pull that gun from?
We have this old man completely freaking out in the fight, he just thrusts that blade with both hands with all his body into it going "HAHAHA I GOT YOUUU" only to be parried and the blade broken. And then out of nowhere he has a GUN IN HIS FUCKING HAND? He pulled that shit out from WHERE IN HIS FUCKING COTTON SHIRT?
THAT is a fucking asspull, which MIGHT just explain where he was holding the gun. The "sensible" and "proper writting" would've been for us to be aware that he had a gun on him or showed it somewhere on him along the fight.
NOT the bloody thing suddendly be in his hand and shoved at the protagonist throat in less than one page because "Of course I have a gun, why wouldn't I?"
