My Girlfriend is a School Idol!

Otonokizaka High School stands on the border of three cities: Akihabara - a pop culture mecca that's evolving by the minute; Kanda - a conservative, cultured city where history and tradition reign supreme; and Jinbo - a quiet area reserved for a more mature, sophisticated population. Amidst this culture clash, the school faced a closure due to the enrollment of fewer and fewer students. 9 students of the school decided to form an Idol Group and gained enough popularity preventing the school from shutting down.
A 16 year-old Tamashi Cai enrolled as a transfer student to put his history behind him and aim to get his school life a 3rd chance. What he does not know Otonokizaka was an All-girl school and he has no choice but to adjust with the rules and taking no excuses for the third time. The 9 girls and Tamashi will cross paths soon.
