Most of his doujinshis are listed on this site:

And there seems to be in total 57 touhou doujinshis, which does not take the small doujinshis into account(such as this one: https://e-hentai.org/g/605831/8ae71b2cd2/)

What's more, just from the year 2009 till now, he has produced more than 1700 pics on his blog, almost at the rate of one pic per day.
(his blog: http://sangensei.blog.shinobi.jp/)

Extras:
(1)In the year 2011, he said he was going to take the college entrance exam or something like that;

(2)Once when talking about kotatsu, he said he was not so familiar with Japan because he had spent quite a lot of time outside Japan before. And it is likely that he might be a oversee Japanese born in South America maybe. Because once he used "Muero" to describe the friendship between Kaguya and Mokou, which seems to be a Spanish word?

Just how many books can an artist draw for one event??

Not complaining, but very surprised. This guy/people must love what he/they do.

@Bigbigfool

Well, good to know I actually enjoy reading, and for his dedication I can only asume he loves working in this.

Also "Muero" is in fact an spanish word wich means "I die", so if it was in spanish I can not imagine what he meant.
