With the spread of smartphones, accidents caused by "walking while using a smartphone" have skyrocketed. Taking the situation seriously, the government enacted the so-called "Walking While Using a Smartphone Ordinance" to regulate walking while using a smartphone. Private "instructors" randomly selected by the government can warn people walking while using their smartphones on the spot, and then decide on and immediately enforce punishment at their own discretion. Ken, a hikikomori NEET, receives an instructor certificate unexpectedly and heads out into the world, cracking down on violators one after another. [Chapter 1] At a street corner, he bumps into Aoi, the daughter of a company president who lives in a large mansion nearby. She seems to be attending a prestigious university and was studying on a smartphone app while walking. Whatever the reason, a violation is a violation. When Ken warns her, Aoi retorts, "Unlike you, I'm not idle." He enforces the punishment as a serious violator who does not follow the instructions. [Chapter 2] Ken spots Sana, an office lady out on business, looking at a map app. As an instructor, he immediately tries to warn her, but she clicks her tongue and pushes him away, saying, "What? I'm in a hurry." However, when he shows her his instructor certificate, she falls silent, and Sana reluctantly accepts the punishment. [Chapter 3] A woman named Mina walks past Ken, who is killing time on a park bench, staring at him with contempt as she uses her phone. He calls her over to give her a lecture, but Mina doesn't even know about the law against using your phone while walking. She has a date with her boyfriend coming up, so she receives a thorough lecture and punishment.
