Yamada and the Seven Witches

Ryu Yamada is a tenth-grade delinquent at Suzaku High, with rock-bottom attendance and the lowest grades the staff can document. Urara Shiraishi is the school's top student and very nearly its anti-social legend. They collide on a staircase, fall down it together, and wake up in each other's bodies. The fix turns out to be another kiss, which Yamada has more questions about than answers. A research club forms around the phenomenon, and the swap becomes the first of seven witch abilities scattered across the student body that Yamada and the club start tracking down.
