Tsuki wa Higashi ni Hi wa Nishi ni -Operation Sanctuary-

Kusumi Naoki was looking forward to a happy uneventful school year at Hasumidai Gakuen High School, with his childhood friend, Honami, and with his cousin Matsuri. While taking a nap on school roof, he has a dream of girl with angel wings falling on him. When he wakes, there is a girl next to him who mistakes him for someone named Yusuke. The girl is a new transfer student who joins his class, and somehow the quiet and uneventful school days that Naoki was looking forward to appear to be a thing of the past.
