Set in the vast grounds of the Blue Lock facility, an ultra-spartan game of tag has suddenly and inexplicably begun!
The participants are 10 players: Isagi, Bachira, Nagi, Reo, Chigiri, Rin, Shidou, Karasu, Itsuki, and Yukimiya.
Under the unreasonable rule that "if you get caught, you immediately get a specially made, disgustingly bad Blue Lock drink," a survival game begins, running away from demons (or madmen) who chase you down with overwhelming physical ability and insanity.
Those who escape with their wits, those who stir up trouble for fun, those who relentlessly target you... Who will survive this chaotic game of tag!?
