YUKARI planning through SNS a reunion of her elementary school after 10 years apart from each other, and met KIRIKO and NICO at the reunion. Three people at once hit it off and would like to go together since then. As they had been keeping same unpleasant feelings toward bully group of their school days, they launched the site in revenge for the friends, guilty they thought. They had never thought that their feelings damaged would be recovered by police or by some stuff of law department. So they upped the cases like peeping and stalker in the video-sharing site for just revenging. The number of viewers increased and also many supporters came in. NICO and KIRIKO were getting slide into extreme violence.
