@Tezcatlipoca : The "smut" tag doesn't belong there. No sex is depicted for the entirety of the manga (or at least I don't recall any, though it happens off-panel once for sure)... and for that matter, the only nudity is male. As I recall, the mangaka got asked to do more fanservice, and responded by trolling the requestors and drawing a lot of naked men. BUT it is entirely in-fitting with the plot, so none of that is forced.
As for the gore... well, again it fits the plot. Nothing deliberately excessive nor unrealistic. Certainly not the level of something like Gantz. But a LOT of characters die. And quite a few sustain unpleasant injuries without actually dying of it. It is most definitely a violent manga... as well as a funny one.
Just keep in mind that I still regard it as the best manga on the site despite the complete absence of meganekko. That is kind of a big deal.
