Jun'ichi and Nemu lose sleep watching a drama series on DVD. Left alone, Aisia joins Tamaki's miko club, thinking that Shinto is an eastern form of magic. She decides to use her newfound knowledge on the school's baseball team, who is known for fifty straight losses without even a hit.

Aisia develops feelings of rivalry towards Nemu, and of affection towards Jun'ichi.

Confused by Sakura's rejection, Aisia asks Kotori about what happened two years ago. She decides to see if everyone's desire can come true through the cherry tree again.

Sakura and the other girls try to get Nemu and Jun'ichi together during a midsummer school day.

Jun'ichi organizes a study session to help finish his neglected homework, but the other girls don't remember that he and Nemu are more than siblings, and even they begin to doubt their relationship.
