Prologue : new sekai, new life, new regrets

A strange yet alerting message notifies the girls of Leo/need as they're walking home together after a day of school. As soon as they open the note, they immediately get transported to their sekai as they realise Luka is malfunctioning and Miku is nowhere to be found.

When a strange door appears out of nowhere, the girls have no choice but to discover the new sekai they have in front of them. What will this place offer..?
