When Masami Iriyoko, Ayama Matsumoto, Dakota Kagome, and Kimi Iko go to a new school, they meet a whole bunch of new people. Some like fighting, countries (don't ask), solving mysterious cases, "wooing girls" and being mischievous. They think their lives are perfect, nothing could happen that would change that. But they couldn't be more wrong. The students at Night Rain High aren't what they seem to be, and all have secrets about their pasts. The world's they used to belong to collide with the one the girls are in. Love, death, fear, tragedy, romance, happiness. The "perfect" world the girls think they are in, is really the farthest from perfect you could get.
