Akari is a closet otaku of 2.5 dimensional idols. One of the things she looks forward to in life is her otaku activities with Onda, a fellow 2.5D idol otaku who looks scary but at heart, is actually like a maiden who is madly in love when it comes to his favourite idol. They go to viewing events, handshake events, collaboration cafes and also collect trading goods together. He's a close male otaku friend who she enjoys sharing interests with but who would have thought that Onda would one day confess his love for her....!?
