I like the character design a lot. I also like the first half of the story...but the second half of the story..not so much (I kind of have a distaste for group...also a distaste for easy-girls if that is applicable here, which it kind of seems (I saw the first chapter and the two non-dark-skinned girls for some reason got involved in festival that got them possesed by spirits and gangbanged (which I dislike) and when they found out about what they did afterwards, they were crying, which was pretty sad...and I guess as a result of that, the tomboy-girl turns into a slut over time...possibly do to influence of the eveil spirit that posseses her latter...).
Edit: Ohh, all of the chapters are in Cultural Anthropology...I got it now. So she wanted to see something that even the small guy hasn't seen, but that "festival" is only for men, so she tried to disguise her self as a man and then...either it's that they were found out or that the ritual is that guys are made to drink semen (I hope not; but in chapter 4 they are definately found out and put in the girl-pen, so it might be the latter)
