>I read from other forums said that Hakika is a Touhou fan. Not sure though.
Have you looked him up on any website for reading doujins? He made a lot of 2hu smut and doujins before starting SEQUEL. He was doing it while making the era of myth games too. Sadly he purged a lot of his non-Sequel pixiv art a while back, but it’s all archived on sadpanda.

His very first uploaded piece of art was this pic. And his first original character was Kakashi-chan.
