Hideki Nishimura (voiced by Toyonaga Toshiyuki) is a young man who loves online games. In the virtual world constructed by electronic information, he believes in the creed that "defense is the most advantageous attack". Once, Nishimura had a love affair in the online world that ended without a cure. The girl he liked turned out to be a middle-aged old man in reality. After this battle, Nishimura, who was greatly stimulated, vowed never to trust anyone on the Internet again. One day, a player named Ako (voiced by Hidaka Rina) confessed to Nishimura on the Internet. Although Nishimura accepted her confession and held a wedding in the game, he always had a skeptical attitude towards each other in his heart. Afterwards, at the offline party held by the union, Nishimura did not expect that not only Ako was a real girl, but also the other two players, Akane Segawa (voiced by Minase Inori) and Apricot Goshoin (voiced by Mao Ichimichi), were also real girls.
