From the introduction:
The sudden brightness that ripped you from your last world has subsided, along with the darkness that followed. You finally grasp your strange surroundings. Victorian architecture, stairways that extend into nowhere, and hallways that take you everywhere. Time does not exists here, and space contradicts itself without a second thought.
Four people share this world with you, three of them are staring at you expectantly, the fourth is taking a nap on your thighs, and drooling. The three strangers announce themselves as Shiki House , and as your guides for entry into this new universe. They reference this place only as The World of Transfer Students .
