You need to make an account on the CBJP SNS in order to view and download the skin files from the creator's page on the CBJP SNS. That's the easiest way, aside from pestering people to do that for you and upload the files somewhere. I'd go and register, their skinning community tends to be a lot more active and skilled than ours.

My Ivis uses the same skin, but recolored. You'll need to use the image files rather than the CS2 since that's for the blonde Ivis and CB won't recognize the HD and BD since they have different identifiers, and unfortunately you won't be able to apply the poly edit. However, everything else is the same, so using the PNG files is fine. If you cannot read Japanese, there was a stickied thread in the guide section that walks you through registering.
Their diary layout is exactly the same, so you should be able to find the album section no problem. Click on the link in the cell that looks like もっと読む to go to the album details section. He's put pictures on each album header so you should be able to find the correct one.
When you get to the albums, make sure you click on the image to open up the full size PNG to save it, otherwise it won't be the right size to apply to the bot.
