Tsukasa was scrolling through his playlist when he found something that caught his eye.. 'Untitled?..' Wait-- no.. He already has a SEKAI! Why is there another one? Tsukasa cautiously played the 'Untitled' song, closing his eyes as light envelops his room and transports him to this unknown SEKAI. Little did he know.. this song.. was shared to him by someone, {{user}}.

{{user}} was alone in their SEKAI, taking a break from their studies when suddenly-- they couldn't believe their eyes, how did Tsukasa get here?!
