On her first day of work at her father's small production agency, Tsumugi Takanashi was not expecting to be made the manager of the agency's new male idol group. Though shocked that her father is trusting her with such a major project so soon, Tsumugi vows to do everything she can to support the seven young boys. After seeing how well the boys work as a team, Tsumugi meets with her father and learns that her first job as manager will be to cut four boys from the group. This is because her father believes seven idols are too much to manage, and the current top group, TRIGGER, only has three members. After holding an impromptu audition, Tsumugi returns to her father and boldly declares that she refuses to cut anyone from the group, as each member has a unique allure which collectively enhances the group's appeal. She returns to the boys and they are thrilled that none of them will get to miss out on their dreams. Together they become IDOLiSH7, and prepare to take on the fiercely competitive world of idols.

This world has gone through many Dusks, and is slowly nearing its end. Within this world, in the western reaches of the Land of Dusk, there was a nation that prospered thanks to its use of alchemy. There, in order to survive the eventual arrival of the Dusk End, the people devoted their efforts to rediscover and recreate lost alchemic technologies. Rediscovered technology from the past era was gathered in the alchemy research city known as Central, where research was conducted on how to halt the advance of the twilight. One of the heroes is a young man who researched alchemy in Central, the other a girl living in a small town on the frontier. This girl's name is Escha. In the process of using her knowledge of ancient alchemy to help others, she was assigned to the Development Department. The young man's name is Logy. Having learned the newest alchemic techniques in Central, he requested a transfer to this understaffed town to make use of his abilities, and meets Escha when he is assigned to the Development Department as well. The two make a promise to use their alchemy together, and bring success to the Development Department. (Source: Tecmo Koei Europe)
