Angel Sanctuary, Volume 11: Of Mushrooms and Boys — Kaori Yuki

Deep in Hell, Setsuna has finally found Kurai. But Hell and everyone in it will be destroyed if Kurai doesn't agree to go through with the marriage to Lucifer--who sacrifices his wives to stabilize his power! And in Heaven, the angel Raphael is trying to revive Setsuna's human body, with poor results. A mysterious power is preventing the resurrection spell from working, but Sara is not willing to give up. But when she uses the angel Jibril's powers to assist Raphael's efforts, they are both flung into another dimension!
