Someone mentioned in aarinfantasy that the Japanese fandoms seem to see themselves as Tsukiko. But that's just a theory. Idk, maybe because of the PV's line, "The protagonist is you" and it somewhat subliminally got into their heads.

For those fanbooks, try otomedream or astost. But they're very strict in giving out download links (or passwords for protected .rar or.zip files) most especially that you need certain numbers of posts just to get the link or the password.
