y'all I just realised smt horrible w this manga. ik its fiction but considering the author is Japanese, it leaves a bad taste.
so MC's grandfather tried to protect Japanese tech after ww2 from America taking it. EXCEPT Japan literally got a lot of tech from experiments done on the Chinese cause they committed WAR CRIMES and America helped cover it up in return for their research from the torture of the Chinese (unit 731)...so like this great kind man (mc gfather) is the one that aided Japan in backing out of the deal that helped them evade the Geneva conventions like Germany....
that's effed up
ik its fiction but aint no way the author is that ignorant bruh
