Manga about halloween

[The Hand That Fisted Everyone]

It's called "I Luv Halloween" and it kicks ass.

Crazy as hell too, someone go check it out.

It's about these kids who go trick or treating, and the main characters sister commits murder, and then sees two teens having sex in a bush, then commits murder again. and a bunch of other stuff happens.
