After a while she woke up but she was in all diferent world that the one she was before , use to happen to her before without knowing why , so she decided to went to the library to find out more about it what was happening to her , but she come to find that this was a family gene that was pass thru her mother that wharever she falls a sleep she would wake up in a totally difent world and would get stuck into it till she make the right choice path to another world she would get changed again transported to another dimension.

when she woke up she was waking up mysteriously in a desert island where she met kito for the very first time , and from there the story starts .
