Help regarding a Japan-only 2008 DS game CD

[mu5n53]

Recently I acquired a CD via suruga-ya.jp titled "もえスタ ～萌える東大英語塾～ ABCDもえスタgo!go!", containing the opening and ending of the Japan-only Nintendo DS game "もえスタ 〜萌える東大英語塾〜".

I'm planning on adding it to the database, but I don't have enough information on the following:

-The booklet front claims it to be a "Comic Market-exclusive release", but looking for information on the following sites:

https://www.comiket.co.jp/info-a/C74...u/list_a1.html
https://www.comiket.co.jp/info-a/C75...u/list_a1.html

shows no information regarding the CD or the company itself.

-Miraishonen, Inc. (未来少年): The company. Their site shows no information regarding the event.

Besides, the official site doesn't load at all, and several company information sites found after a simple Google search show no recent information.

As you can see, I can't create the entry because I don't have enough information.
I'm probably looking in the wrong places.
If someone would be kind enough to share where I could find the information I am looking for I would be really grateful.

Also, I have scanned the booklet and the rest of the cover files entirely, so if any of you request them I will be happy to share.

Thanks for reading up to here. I hope you can help me, please.

I'm not sure if they were at other events but they definitely had a booth at C74, #647 to be precise

Thanks a lot for your reply.
I relied way too much on my browser's text search function.

Anyway, I just submitted the entry.
If there are any details missing, I commit myself to find and provide them.

Thanks once again!
