From the publisher:

After a frightening turn of events leaves Hiruma riding the sidelines, Sena finds himself in the role of backup quarterback for the Devil Bats, and it's a tougher job than he ever imagined. Meanwhile, Kurita still hasn't gotten over his inability to protect Hiruma from the vicious Rikiya Gao, but some last-minute help comes from the unlikeliest of teammates. Will Kurita snap out of his funk and fight on before Gao sends Sena to the emergency room?
