Okay there is his userpage...
https://www.nicovideo.jp/user/20875633And I can tell that he made his own MADs from 2011 to 2012, During the time where NicoNicoDouga started peaking at MADs
It was the second video he ever uploaded!
There is unfortunately no desription..
BUT in the first video there is a description and when translated it shows that he had done the music and looping a bit poorly..
His first video..
https://www.nicovideo.jp/watch/sm13948862(Japanese: 昔刻みの練習に作った音源です。動画は適当にシンメトリークッキー☆を、一応SIKがメインです。ループ若干失敗してるけどそこら辺は勘弁して下さいね(棒読み))
(English: It is a sound source made for practice in old days. The video is appropriately symmetrical cookie ☆, and SIK is the main one. The loop is slightly failing, but please understand that (bar reading)
He also has done a lot of MAD's from the Cookie(:star:) version..
A famously failed Touhou Fan Voice drama that got known for memes instead..
Here's the wiki of this:
https://cookiewiki.org/Main_PageAnother one thing I notice is that it might have been one of the first if not the FIRST EVER "I'm so Happy" remix. Since there were a LOT I mean a LOOT of videos that sorta copied this style...
I found a playlist of it on YouTube showing all the different versions...
Ranging from Misaka (the tsundere) to literal Oreo O_O
Some japanese really like to cook something out of japanese commercial ads..
(NicoNicoDouga is super weird sometimes...)
