Oh My Goddess! Vol 18

From the Dark Horse edition

"Who would have ever thought one of Skuld's inventions could go wrong? Er ... don't answer that, but her tinkering with the time-space continuum has left Belldandy and Keiichi trapped inside their own living room ... because it's now infinitely big! And uncanny events await them outside as well, as a ghost haunts the mountain pass between the two campuses of N.I.T.-- causing Bell and K1 to do a night ride in tandem to solve the mystery! Plus your fan art and letters!"--Page 4 of cover."
