Let me explain...I'm the guy who colored most of these.
These were made to troll some random fan fag (called angrytouhoufan or prgs, among several other names) who literally worships touhou And will death threat anyone who says anything thing bad...so, the guy who drew them (called trextrex65)decided to make a lot of them to troll him...and it worked!
Prgs then made 1000 sock accounts to try and dislike the vids to hell and back. Only for to encourage trextrex to make more.
And the poor cute war has been going on ever since.
