it was probably a way to gain her trust just like when people get dogs from the street they dont use medieval armor, its to trasmit a sense of bond still dumb
probably now for the trauma the both of them are going through nekotan wants to die it seems as the big bang is the end and start of everything the reason would probably be the death of his mom as in the start of this chapter we see his grandma giving him smtg which is probably a memento of his...
The reason she was that bad at aiming wasnt just because she had no training but too because you need to have two eyeballs to notice distances right which i believe is quite important in sniping
i am not talking about that i understand it, what i am saying is that its hella annoyin every chapter the mc moaning for zero reason, alright the hospitals and higiene are backwards yes but no need to do all that internal screaming.
everytime the mc scream at us due to oh boy the victorians dont do this or that i just want to punch him so much stop screaming and start doing something.
