Not surprising, HxH is well-known work among Shota circle and Fushoji circles. Yoshihiro Togashi's work usually have strong fan representation in those two group. Heck, I remember not too long ago, earlier this year, there was a Japanese poll on best manga tsundere girls and Hiei somehow not only manage a vote he was ranked in top ten.....
It's kind of funny, the same fan boys who claim HxH is by far the best Shonen manga and other current shonens are crap tend to ignore that a good portion of Togashi's fanbase are women and girls, the demo-graph they often happens to hate the most among ACG fandom.
