2045, Tsuki Yori.

——She had a dream. She dreamed of becoming a butterfly. She freely crossed the glittering stars, and was eventually drawn to the "blue". Her body was heavy, the sky blue, and everything she touched seemed to shine for the first time. Butterflies move their wings with all their might and head somewhere. She's high, high - in her longing for 'I want to be'. Without resting, it just looks up and flaps its wings.
