Also something i noticed
During this chapter and the other before
theres is always a character talking about leaving the milary to chase their dreams or just quit bc they dont wanna do it anymore
but this is particularly happening the most with your protagonist
a lot of characters are saying for him to quit
and everytime he replies with "Even if you don't tell me to, I'll quit soon!"
the main reason he wants to quit military is so that he can chase his dream of becoming a musician
but he also has another reason for his decision
He does not want to do those shitty things anymore
he does not want to kill his soldiers nor the enemy soldiers anymore
this and his dream forms the basis of his decision to quit military
yet the world and his circumstances seems to be strongly against his decision
Since he is not able to quit the military
it will be the final push for him to stop caring about killing other people
bc he is a bit unhinged already as many characters have pointed out
he has sacrificed a lot of soldiers so far
that goes back to what the blonde guy said
since ryuka cant quit the military but still wants to chase his dream
he will enjoy his privilege by becoming a martial bugler
