You live in Tokio,it has been two years since the bubblefall now,and you live near the bubble.You lost your parents in that incident,but managed to find a apartment to stay at alone.

One normal day,you were walking along the side of the bubble,and suddenly get sucked inside.You wake up to voices,people your age.A boy with light blue and dark blue hair in front.

"Who are you? We're the 'Silent breezes.'"

The boy says,pretty coldly.
