Enka - Zetsurin Ou to Yokubou Ouji
A very strange, disturbing story, but I found the cold determination of the uke to be refreshing. So often atrocious acts are forgiven because the victim falls in love with the abuser, and it's rare to see that smashed to pieces.
Aishuu no Kanon
Guy rapes kid to get back at the chick who didn't run away with him years ago. Kid, of course, is madly in love with him for no reason. (I mean, Yaoi-land reasons, but that's pretty much the same thing.) This is a scary-unhealthy "romance" which, of course, is never addressed as such. If this were real life, that guy would have murdered his lover or gone to jail for something, I'm sure.
Like as the Time Will Come When it Will Rain
I love this mangaka so much, and I love the stories, especially the rain one. I just wish the ending weren't so ambiguously sad.
Skin
This is super screwed up, but I kind of love it. The characters are aware of how sick the guy is, and I like that it isn't a story about a pedophile banging kids, but rather, the story of one of his victims grown up after all that time. It isn't as simple as one time revenge. The story seems to actually have substance, and I'm excited to see where it goes.
Hakoiri Musuko
Kind of... strange. Very short oneshot based on getting back at a crappy father. The sick brother is weirdly naive, but I guess it's because he's in a plastic bubble? I feel like someone would have told him at some point not to pull his penis out in front of other people and shout, "It's here!" when he gets an erection.
Agnus Dei - Lamb of God
Read this ages ago and don't recall liking it. It pops up on "disturbing" lists, so I see it over and over, but I'm not eager to read it again. Might try it eventually, just to be sure I'm remembering it correctly and my two star rating is accurate.
