World End no Niwa

World End no Niwa (ワールドエンドの庭) is the ninth album by Yui Horie. It was released on January 7, 2015, as a standard edition and two First Press limited editions, that came in a Red or Blue variation.

Album covers and insert photo booklets were shot in England, with the location having been decided before music production had even began. The focus of the shoot was heritage buildings and castles. As a result of this decision, Gothic, Classic and Mysterious elements were purposely included within the musical composition. This was in addition to the "strange mood" musical stylings of previous collaborator Ryujin Kiyoshi, which was seen as complementary to their intended art direction.

The album achieved a peak position of fifth in the Oricon Charts, staying in the chart for seven weeks.
