Why did I not find this group until now? Oh well.

Hello. You may call me Abyss. As you can tell, a like Vocaloid, my favorites being Gumi, Rin, and Oliver. I think that covers what you need to know about me. 

About the new Vocaliods that you have posted, I have to assume that Annon and Kanon are twins, but that could as well be alternate versions of themselves. You can never be sure with Vocaliods.
