It is a story about 5 girls who escaped from the death and saved millions of people. It all started in a small town, a friend group of 5 two older girls-15 years- Luna & Kyoko and 3 younger girls-13- Lilly,Ruki & Himiko. If we see their first meeting it's not good they didn't get along well instead they got into an argument like older friends vs younger friends. But the next day they became friends if anyone see them at that time they think that the girls are being friends for years.
Time passes their bound became strong. They all meet at the tution. Even tho they study at same school they don't have the time to meet at school cuz of luna and Kyoko being 10th class.
But one day luna and Kyoko starts to feel something strange in the behaviour of others and it didn't take time for lilly, Ruki and Himiko to notice the same thing. An usually they met in their tution but it is different not like the other days it is awkward and everyone are in their deep thoughts the air is suffocating it is hard to breathe for them every one taking deep breaths and the silence got break when lilly talked "guys, do anyone of u notice the strange behaviour of others" "yes, I noticed even before u and I told Kyoko about that but we take it lightly thinking it is a small matter but it's not. It's really different they are giving me chills" Luna said.
