Adapted from the popular manga, this drama is set in the town of Higashimikawa in the prefecture of Ehime and is about Kamogawa Yoshiro, an average teenager, with no special talents nor outstanding abilities. Until one day, he could suddenly hear other people's thoughts. He could tell that Hayashi-sensei harbors some ulterior motive when it comes to dealing with the new transfer student, Asami Sae. Yoshiro admires Asami, and thus with his newfound powers, he intends to protect her from Hayashi sensei. With that "I shall protect you" thought, came another, "I shall save the world!". Later that day, at the Cafe where he often hangs out, he realises that his childhood friend, Hirano Miyuki, and the Cafe owner, Nagano Terumitsu, have also acquired new powers.

Meanwhile, upon hearing the news of how many townspeople are suddenly acquiring special powers, the mysterious teacher and his assistant decide to move to the town of Higashimikawa...
