Via Crunchyroll: New VOCALOID Tone Rion's Demo Song "Thousand Regrets".
The song will be officially released in Japan on December 16th. The song "Thousand Regrets" was produced by Nijihara Peperon aka PeperonP. You can listen to the demo song in the video below:
The song is really nice, isn't it? And Tone Rion's outfit looks adorable; I hope to see some cosplayers tackle her cyber-pop wardrobe in the next year at upcoming conventions.
