Yamada Ryu, a second year student who attends the prestigious Suzaku Private High School, is a problem child who comes to school late and leaves early, is prone to fighting all over the place, and even nods off in class. One day, he falls down the stairs with the honor student Shiraishi Urara. They faint, and when he wakes up in the infirmary he's turned into her!

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

"They won't give us a club budget?" Miyabi is unhappy the Supernatural Studies Club can't move forward with their research because the student council won't give them funding. 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.

"Keep this a secret from Shiraishi!" Just as Yamada decides to keep the fact his kiss' power has changed to "Charm" a secret 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! Elsewhere, Nene is irritated that Yamada hasn't become charmed by her kiss and shown up like he's supposed to.

"It's summer! It's the beach! It's a summer retreat!" The Supernatural Studies Club holds a summer retreat at the club house to find volume two of the notebook containing the legend of the witches, but Yamada's spirits plummet as he is forced to take supplementary lessons and exams with Otsuka Meiko, Tsurukawa Hideaki, and Kameda Mitsuru from the Manga Research Club.

Yamada begins searching for the witches and visits the home of the fourth witch, Sarushima Maria, who is a shut-in taking a break from school. When they're alone, she tells him that her power is to see the future of the person she kisses.

Yamada's group gets roped into making the group of first-year problem students lead by Takigawa Noa behave in order to open a yakisoba bread stand at the cultural festival. Noa is a witch, and appears to see the past of the person she kisses and latch onto their shortcomings. Worst yet, she seems to have volume two of the notebook containing the legend of the witches!

Suzaku Fest is here! Thanks to copying Maria's power to predict the future, Yamada's fortunes guaranteed to strike home make the Supernatural Studies Club's yakisoba bread shop a huge success. Meanwhile, Maria confides in Yamada and tells him she wants to erase her witch power. "I want to kiss and fall in love like a normal person."

The Supernatural Studies Club meets Miyamura's sister, Leona, in their search for the seventh witch. She has dropped out of school in order to escape from that witch's power to erase memories. The instant one learns her name, all of their memories related to witches will be erased.

Unable to stand by and do nothing after seeing Urara's tears, Yamada tries to kiss her to prove she's really a witch, but she refuses. Yamada and Tamaki, unwilling to give up, continue trying to find a way to restore everyone's lost memories.

Yamada must get all the witches together to conduct the seven witches' ceremony, and the last three needed are Urara, Mikoto, and Rika. Hoping to at least save Urara, Yamada heads for Mikoto's house along with the student council president Miyamura, but they're stopped by Miyamura's sister Leona.
