A Meek Little Brother Like Me
Haha, this mangaka is a big fan of sociopathic, manipulative characters. I love the subtle build throughout, just little things that suggest something is off with the sister, and early on you start to wonder about that accident. Definitely another dark comedy here. I liked it the most out of what I've read by this author, though. Very twisted little snapshot about how the most dangerous, bloodthirsty people can wear a bland smile and sleep in the room right next to yours.
Sacrifice Mansion
Yeah, you can tell this was her/his first story. I like this mangaka's typical approach to dark humor and the sinister feeling underlying the other stories. This one was just clumsy and obvious. It was kind of funny, just the way that the characters start off, but nothing was ever explained, and there was nothing original here. Bummer. I wouldn't start with this one if you want to enjoy this author, though I have to say that most of the work is for those who appreciate the morose beneath the seemingly cheerful and innocent.
Citizen Ogre
These oneshots are very hit or miss. Dark humor, for sure, but some have a greater impact than others. I get the joke, but there wasn't enough there to really make it worth it.
