KGMC-007: Kogado Studio Natsu no Kaidan 2006 ~ Taikan Ondo ga 3-do Agaru...

[CHz]

I've seen the catalog number for this album reported as KGMC-007 and KGD-6060 (perhaps meant to be KGD-06060). KGMC-007 works chronologically, but Suruga-ya gives KGD-6060, and they're usually super reliable when it comes to catalog numbers.

I added some scans that at least confirm that KGMC-007 is on the materials. KGD-06060 may also still be valid in some way.

Awesome.

Even more awesome: I see KGD-06060 on the disc (second to last line of text), KGDF-080 on the back of the booklet, and KGDO-080 on the obi next to the barcode.

I think I'm okay with just sticking to KGMC-007.
