After mustering up the courage to propose to a girl in an online game, naïve otaku Hideki "Rusian" Nishimura is devastated when she flat out rejects him. To make matters worse, the girl reveals that she is actually an older man in real life. With his dreams crushed and his heart broken, Rusian comes to an abrupt decision in the midst of his raging fit: he will never trust another girl in an online game again. Years later, Rusian is now in a guild with three other players, one of whom possesses a female avatar by the name of "Ako." Ako is deeply in love with Rusian and wants to marry him. Although he entertains the possibility that she might be a guy, Rusian accepts her proposal, claiming that her gender doesn't matter as long as she is cute in the game. However, after a discussion between guild members that led to all of them having an offline meeting, Rusian finds out that Ako, along with the other members, are not just girls, but also his schoolmates. Nishimura Hideki is a young man who once confesses to a person he thinks is a girl online, only to find out that the person is actually a boy. He keeps this story secret and swears he'll never trust a girl online again. However, one day a girl online confesses to him, and it turns out she is actually a beautiful girl named Tamaki Ako. Ako cannot tell the difference between the online world and reality, and she is a loner who has trouble communicating. Hideki and his friends from the guild decide to work together in order to help her.
