One of the things I absolutely adore about Denji's character is that he doesn't say some profound hero things like protagonists often do in other series. He doesn't say "I have to live so I can experience being human" or something like that, he says "As long as the world has grub and girls, I still have something to live for." It's simple and to some may seem shallow, but it makes perfect sense for Denji to say. He wasn't raised on some lofty ideals, he was never educated, he never read books, he's a 17 year old boy. His statements like this said by any other character would be considered vain and shallow, but when Denji says them the sentiment and the simplicity is beautiful. Is there still good food? Yes. Is there still cute girls? Yes. Then I have to keep going.
