Cross Concerto

It was spring, the season of new beginnings. Satoru finally broke free from the closed remote village where he had been held captive as an unwanted child, and entered the same school that his late mother attended. However, he was surprised to find his twin sister Ruri and her attendant Kyouka waiting for him there. He met the cool senpai Touko and occult-loving student council leader Mirai and gradually got used to the dormitory life. However, there were figures working in the shadows; will they find out the truth behind the events around them?
