With the club recruitment week happening at First High School, Honoka and Shizuku, who are all-round outstanding students, are asked by various clubs to join. When they find themselves mobbed by club members, Eimi comes to the rescue, and the three of them become fast friends. One the way home from school, Honoka and her friends witness Tatsuya, who recently became a member of the Disciplinary Committee, being attacked by someone. Eimi, who is driven by her interest in this incident and in Tatsuya, decides to investigate who the attacker is. Honoka and Shizuku get pulled into Eimi’s investigation and the three girls end up forming the Girls’ Detective Club.
I just hope that the people coming after me
will be satisfied with high school-level spite.
آمل فقط أن يكون الأشخاص الذين سيأتون بعدي 
.راضين عن مستوى الحقد في المدرسة الثانوية
Wenn der Täter mir einfach nur ein
paar Streiche spielen will, ist es okay.
Espero que esto no sea más
que una riña escolar.
Solo espero que esto no sea más
que una pelea de instituto,
Tant qu’on en reste
aux plaisanteries d’écoliers, passons,
Se os que me têm como alvo são alunos
que querem fazer besteiras, tudo bem.
