A certain idol group now hugely popular in Akihabara. While their fanbase is mostly male, they actually have a surprisingly large female following too. Among them is Kokone, who secretly harbors her otaku side but can't bring herself to come out about it, not even to her friends. Overwhelmed by the intense atmosphere of live concerts, she's never actually attended one, spending her days merely collecting merchandise. That is, until she met someone through an online idol message board—another girl facing similar struggles—and the two began sharing their experiences closely. One day, the other girl suggested, "Want me to take some cosplay photos of you?" Thus began their private photo session, just the two of them. This story unfolds a unique concept: targeting not male idol fans, but women like Kokone, proving such an approach can indeed succeed.
