An angel, a demon and an elf find their soulmates in the human world. Three girls will be the first humans in over centuries to see the world of non-humans... Things won't be so easy, though. First, the non-humans would have to win the hearts of the three reluctant humans. An unwilling, violent girl who doesn't believe in love, a silent, pessimistic girl that is afraid to trust and a cheerfully, insane girl who has detached herself from humanity... This will be hard, indeed.
