Yukiya, who is "possibly" 14 years old, DJs by himself. He's been listening to house music since he was a child, thanks to his father's influence, and he posts videos online. He wishes to communicate with someone. He want to be renowned and influential. However, getting harmed is terrifying. One day, in an attempt to gain more views, he does something irreversible. And he witnesses a live broadcast from "that world." Yukiya feels he can't achieve anything alone, but that if he works alongside someone else, he can do anything.
