Shotaro Taguchi is a newly recruited attorney. As part of a new "school lawyer system", he is sent a middle school. There he encounters an angry student’s guardian who came to complain about her daughter's corporal punishment. The guardian threatens to sue the school but Taguchi kicks the person out from school. A few days later, the corporal punishment issue develops to an unexpected situation. The guardian sents a document with the student's homeroom teacher Mochizuki signature, admitting to using corporal punishment on the student.
