Ju to Usagi to Twintail (Sakura no Mori Binko) [Light Novel]

[Machine Translation] One experimental city, Shinichi City. In this city, there was a school where students were allowed to carry guns. Naturally, there were those who had guns and did mischief. Ordinary people, of course, could not stand up to them, and the law could not judge them, so they had no choice but to turn a blind eye, and many people were crying.... In the midst of this situation, there were four girls who stood up to the authorities and violence without hesitation. Since they all had twin-tailed hair, people began to call them "Burning Hare," and they became an urban legend. Sumio Amano, who works for a magazine company, is 26 years old, but with her childlike appearance, she is just like a high school girl. The clumsy Sumio makes a mistake she should not have made as an adult, and ends up dealing with the urban legend "Burning Rabbit"... As Sumio investigates the "Burning Rabbit," she learns of an incident at a school where students learn how to handle guns. Sumio, who has a childish face, makes use of it to go undercover at the school, but a certain trap awaits her.
