There's not much to go on, so I'm left to speculate. Cosmo arrived in Videoland in desperate need of help. As luck would have it, Cosmo came across Akiko who seemed more than capable of handling the job. After a few nights of travel, Akiko found herself at the entrance of Saladaria where she quickly made her way past the gatekeeper who was sleeping at his post. While exploring the city, Akiko found herself sidetracked by the sights and sounds of a small, yet joyous techno music festival taking place at the far end of Saladaria's central park. This potential "gaiden" is evidenced by the last minute of the piece and may hint at what to expect from the fourth song in this series. Only time (or rather Bertn) will tell if my speculation holds true. Until then, thank you for sharing this lovely piece with us and the audio portal. <3
