Game Summary: One year after the events of Tsukihime, Shiki Tohno 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 Len, the creator of the dream, if he wishes to escape.
The gameplay is much more dynamic than in Tsukihime. It uses a vastly different system in which the player goes through each of Shiki’s “days” in the dream. The number of choices presented to the player in Kagetsu Tohya is also significantly larger than in Tsukihime. Also, due to the plot structure, the timeframe of Kagetsu Tohya is not linear like Tsukihime, but circular; that is, after completing one “day” in Shiki’s dream, your status is automatically saved and you have to play the same “day” again, but with different choices. The days do not progress; rather, every time a day is completed, what you have accomplished in that day is saved by the computer. Eventually, you will come across the ending for the game after accomplishing everything that comes before it.
