Tsumugi Takanashi did not expect to be named manager of the firm's new male idol group on her first day of work at her father's tiny production business. Tsumugi, however surprised that her father is entrusting her with such a large job so quickly, swears to do everything she can to help the seven young boys. Tsumugi meets with her father after seeing how nicely the lads work together and learns that her first assignment as manager would be to eliminate four males from the group. This is due to her father's belief that managing seven idols is too difficult, and the current top group, TRIGGER, only has three members.
