Well its smth I like in this manga:
Its just so random and that makes it look like its genuine without the unnecessary overheroism and stuff…
People die, main cast, side cast, bad guys good guys...if he happens to do poorly be on the wrong place at the wrong time or makes a bad decision anyone is a potential goner...
Without the he is the hero he wont die so you can expect him to be saved in last second BS
Thats my take anyway... ah yes the best thing overall for me is how it displays human nature...so in this case Inaba just plays the cowardly human role most of human beings probably would...the only funny thing about it is that he manages to survive with it for so long
