I tried finding the interview again because I swore I read Noda saying that theme about parents and children, directly and here it is again, plainly stated in the chapter, with both the death and birth of a child.
I can't find it but it's a recurring theme through this manga: especially that tattooed convict who also lost his kid to lightning and began to lash at the world because of it.
I know I read that interview around the time I read this https://mobile.twitter.com/KamuyCentral/status/1329591175913738241 but now I'm wondering if I got confused along the way because I read a bunch of GK stuff in one go.
