I stumbled upon the Shindere Shoujo to Kodoku na Shinigami manga and read some of it on a whim, but it turned out to be pretty interesting.
It's about a girl called Akira who lives on a small peaceful island, and a transfer student named Matsushirou arrives and warns everyone that people who get close to him die. And then quite a lot of other stuff happens~
Has anyone else read it?
