Question about a couple of UTAUloid derivatives

[Kazumimi]

Hi there.

I was looking for information about a couple of derivative characters based on Sukone Tei (specifically Sukone Teiru and Ika/Squid Tei). I found Nicopedia and pixiv dictionary entires for both of them but can't find the following information:

• If the two are officially recognized derivatives or were created with permission of the rights holder to Tei's voicebank (like Kasane Ted from Teto, for example)
• The release/creation date of them

I'm trying to create wiki pages for them both, but don't feel right leaving the pages with missing information.

Small correction to my original post since I can't edit: Ika Tei is actually called Sukone Teika. My bad.
