Tsuki wa Higashi ni Hi wa Nishi ni: Operation Sanctuary

Since my parents were both killed by an accident, I, Kusumi Naoki, have living with my uncle in his house. "Nano-kun, you'd better wake up, or you'll be late for school" The new school year starts today. My childhood friend, Honami, still comes by to wake me up, although I often complain that I'm too old for that... Today, we'll become sophomores of Hasumidai Gakuen High School. When we walk to school, my cousin Matsuri, who this year starts to go to the same school, passes me by: "Nakoki, I'll be going first". I think this normal life will continue forever... However, when I try to take a nap on the roof, a girl falls on me. "...Yusuke?", she asks. This girl, a transfer student who becomes my classmate, seems to take me for another person. Gradually, as time goes by, the normal days supposed to pass routinely begin to change. * Based on a game by August Soft.
