@Viper_12358 a lot of artist has been selling digital raws instead for this comiket (including this doujin). Only a few odd ones are still physical only.
@ NSFWSB and @Viper this FuyuComi was a small one, less artists than usual, less people allowed to go, and almost no foreigners in Japan. So artist who couldn't go sold digital, some who could go still put digital given less people allowed, and those who usually scan (ch/kor) weren't there. So more digital this time. I do hope one day digital will be high quality...
