Yamada Ryu is a problem student at Suzaku Private High School. He comes to school late, starts fights, and even sleeps in class. One day he falls down the stairs with the honor student Shiraishi Urara, and they wake up in each others bodies!

Ito Miyabi, who loves supernatural phenomena, joins the Supernatural Studies Club. Miyabi shows off her supernatural paraphernalia so proudly that Yamada and the others can't tell her the truth: they only want to use the clubroom to kiss.

Miyabi is unhappy that the student council won't provide funding for the Supernatural Studies Club's research. Yamada isn't interested initially, but quickly changes his mind once he learns he could buy a microwave to warm up his beloved yakisoba bread.

Yamada is less than thrilled about going on the school camping trip, but changes his tune after discovering how fun the trip will be after switching bodies with Urara.

Just as Yamada decides to hide the change to his kiss' power from from Urara, she urges him to switch bodies. He'd better go see Odagiri Nene and get his power back to normal in a hurry!

The Supernatural Studies Club holds a summer retreat in order to find volume two of the notebook containing the legend of the witches. However, Yamada's spirits plummet as he is forced to take supplementary lessons with the Manga Research Club.
