That's Shamo and i feel highly ofended because I'm a girl and I like seinen very much. In fact I love seinen. That doesn't mena I don't enjoy shoujo, josei, shonen, yuri, yaoi or any other kinds. Every different category or genre from comedy (Kyou kara oreha FTW for example

) to the most serious psychological manga have their diferent appeal but there are so many and so little time to read them T_T
PS: The image ypou posted is in volume 5 chapter 43 (on a remote island) page 14 in mangafox at least.
PPS for Leokiko: If you want to see some cringe worthy (although apealing for some people) images, just check out a lil' visual novel called Enzai Falsely Acused. Curiously the majority of fans are girls XP The plot is nice but the continuous sadomasochistic jail raping and such is way stronger than most I've seen. Although 15 minutes in certain internet places are more than enough to go looking for brain bleach *cough certain 4chan boards cough*
