The Sailor Who Fell from Grace with the Sea

I couldn't find anything about this online, and unless the trope of "a group of early teenage boys with a psychopathic leader that act like all knowledgeable philosophers and think aging will dumb them down" is a common one in Japanese fiction, I feel like this book inspired Usamaru Furuya's Litchi Hikari Club a manga about a group of teenage boys doing psychopathic things and trying to reach immortality or whatever. It's a gorey twist on the fear of puberty and growing up expressed through extreme violence. Anyway, this book had this although it could be more political I feel. And reading some reviews to make something of it I guess I'm right. Not that interested in that aspect, though it's important to note it. Mishima was a "bit" of a nationalist. Anyway these teens are naive, but not innocent. They view life through the lense of heroism and glory, and living with an amazing purpose. Naivety is a good word for being obsessed with glory,honor and the like. They're frustrated by mundanity of adult life, they hate their fathers, they don't want to become them. I really really liked this book, but I'm a bit frustrated as I can't exactly put into words why I liked it. I guess I like seeing children being scheming little sociopaths, although the cat scene was really uncomfortable to read. I don't like reading about animal violence.
