There was a post like this on a certain major bulletin board. - ``[Urgent recruitment] Let's do some mischief tonight in Tokyo lol'' is the post. - When I looked at the posts out of curiosity, the thread was surprisingly lively. - When I asked the poster for details, he only told me the time and meeting place. - ``It's all fake anyway...'' I thought as I walked in, and there I saw several men looking at me with bleary eyes. - This is the whole story of a video posted by a group of people who attacked people in their sleep.
