Rumours of girls living on the streets. For some reason, they cannot inhabit the regular world, but instead spend their lives on the streets. Though they may be in the same city, they did not live in the same world, and people had started calling them "Alice of the alleys".
How, why, did those girls become Alices? To answer this question, the protagonist, a freelance writer, disguises himself as homeless, and encounters three of these Alices.
Rana, a prostitute with an innocent soul. Sayaka, a girl whose harsh aura seems to say that she hates everything around her. And then, Miu, a girl who evokes a mysterious atmosphere.
Though our protagonist started off with mere curiosity in his mind, as he begins to learn of the girls' pasts, he soon starts harbouring feelings that go beyond the ones of a reporter.
