The secretary of 765 Production, Kotori is open-minded and smart, but also sometimes shy.  Due to her position in the agency, at slow hours she can often doze off or start to daydream about outrageous things. She also spends much of her free time during workdays browsing 2chan, and because of this she is often thought of as being a pervert. Despite not being an idol herself, Kotori loves to sing. While Kotori's exact age has never been revealed, we know that Kotori is a little older than Azusa (making her somewhere in her twenties).

765 Production Studio manages the unique talents of 13 professional idols as they slowly make their way to the top and become country-wide celebrities. But the girls' journey is far from just fun and games: hard work, sweat, and tears are some of the prerequisites needed to flourish in this industry—and for 765 Pro in particular, a watchful eye out for their rival, the infamous 961 Production.

As the girls' fame grows, however, their time together as a family diminishes, and now the very popularity they sought is threatening to tear them apart. A difficult balance of work and bonding must be achieved, or they risk everyone going their separate ways. The personal and professional ordeals of these idols can't be conquered alone, but with each other's loving support, any obstacle or hardship can be overcome!
