On a holiday morning, Lucy was lying in bed playing with her phone. Her mother entered the room and scolded her, saying it was already 9 a.m., but Lucy hadn't left her room to shower or tidy up. Her mother warned Lucy that if she kept using her phone endlessly, she'd someday turn into a phone herself. Lucy laughed it off, calling it impossible.
The next day, Lucy woke up in a vast place surrounded by countless stars and planets. Confused, she wandered aimlessly until a goddess-like woman appeared. Lucy asked who the woman was and where she was. The woman introduced herself as Galaxia, guardian of the Milky Way galaxy. Lucy asked if she was a goddess, but Galaxia clarified she was not. She explained she was a cosmic guardian born alongside the Milky Way, created by an unknown entity to maintain the galaxy's balance. She also mentioned other guardians likely existed in distant galaxies. Lucy then asked why she was there. Galaxia revealed Lucy had died and was now in the Aetherium Dimension, a sacred realm accessible only to spirits awaiting reincarnation.
Lucy realized she was dead and asked how she died. Galaxia explained her phone had exploded from overheating while charging overnight. She added that Lucy had contributed nothing meaningful to society in her life. As punishment, Galaxia decreed Lucy would reincarnate not as a human, but as a smartphone in a backward world, hoping someone would use her to advance civilization.
Galaxia sent Lucy to Vuldoria, a planet with a magic-driven civilization devoid of science. As Lucy was hurled toward the planet, she remembered her mother's warning about becoming a phone. She never imagined the "impossible" would come true.
