Story
Kagetsu Tohya consists of "Twilight Glass Moon, Fairy Tale Princess", the long main story with many branches, and several shorter side stories that are unlocked one after another after related events in the main story have been read. Ten of these side stories are combined as "Ten Nights of Dream".
Twilight Grass Moon, Fairy Tale Princess
One year after the events of Tsukihime (presumably from the "Good Ending" of Arcueid path, as none of the characters are dead), half of July 2001, Shiki is a victim of an accident. After this accident, Shiki awakens into a strange dream wherein he repeats the same day over and over. There are infinitely many endings to the day, but it always begins anew after each day. Eventually, Shiki discovers that he must find Ren, the creator of the dream, if he wishes to escape.
