The Girl in Twilight Collection

Every day, Asuka and her friends Nana, Mia, Yu and Chloe go to a certain shrine to find out if an urban legend they heard is true: that if you set your radio to a random channel at 4:44 PM, and pray really hard, you can open a door into another dimension. It's a game, really, and the girls don't take it too seriously. Until the day it works and they find themselves in another world where there are people who look suspiciously like them. But messing around with alternate realities is dangerous, and as the girls travel from one world to the next, they find themselves thrust into increasingly perilous situations. Will they all survive? Will they still be the people they were when they started? The revelations unfold along with the dimensions.
