This is a nice light song from KAITO, found it recently but only decided to add it here just now.I'm surprised I haven't got wind of this in youtube until now when it's been there since 2008.
After finding myself in VOCALOID wiki once again, I decided to visit KAITO's page as per usual.Re-reading the "Append - Future of Kaito" as per habit, I saw the link to this.
