The World God Only Knows, Volume 17 (The World God Only Knows #157-167)

With the Sick Event, Keima attempted to get closer to both Ayumi and Chihiro simultaneously, yet it is too difficult for him to determine if his plan succeeded or not. Later that day, Diana requests for her currently "awakened" sisters to come together and revive Apollo from her sleep. Even though Keima was able to converse with Apollo personally, the Goddesses couldn't break the spell without their last sister, Mercury. Meanwhile, in Hell, Haqua faces crude torture, but is unexpectedly saved by no other than Dokuro Skull. Given a new task to save New Hell, Haqua heads back to the Human Realm.
