Taichi is the main protagonist and a big professional wrestling fan. He and four others formed the cultural club because their school did not have the club they wanted to join. He is generally selfless and will usually try to help others in need. He confesses his love to Iori in the Hito Random arc, however he gets rejected since it was believed she was going to “die”. Taichi confesses to Iori again in Michi Random but was rejected because Iori believed Taichi did not know the real “her”. During the events of Michi Random, his feelings began to change and then confesses to Himeko by the end of the arc.
Iori is the easy going president of the cultural club. She lives alone with her mother who is seldom at home. Having previously had a violent stepfather, she had learned to alter her personality to fit the expectations of others to the point where she is unsure who she was originally supposed to be. She is in love with Taichi, but decides to postpone their relationship until the phenomena was over. In Kizu Random, she finds out that Himeko has feelings for Taichi, too; Iori confronts her and later encourages her to confess to him. By the end of the Kako Random arc, she starts to question whether or not she has feelings for Taichi and if people really know the real her. She is sometimes controlled by Heartseed when a phenomenon is about to end.
Himeko is the vice president of the cultural club, who has a contrasting personality with Iori. She often reacts violently to Taichi or Yoshifumi’s jokes, and is nicknamed “Inaban” by Iori. She was a computer club member but quit after having an argument with the president of that club, and then joined the cultural club. She is generally distrustful of others and worries a lot, even more so when they begin swapping bodies. Between them, she is the most calm and rational when dealing with unexpected situations. During Kizu Random, Heartseed confronts her in coming to the realization that she has feelings for Taichi when she was pretending she did not know. She confesses to him after the class trip by the encouragement of Iori, declaring that she would make him fall for her even if he was in love with Iori. Over the course of the series, she gets more and more attached to the group, especially Taichi, and softens her sharp and rational personality. In the end of the Michi Random arc she starts dating Taichi and in the end of the light novels they are still a couple.
