Ham hasn't uploaded anything in years, and its Twitter account is no longer available.
Ham's legacy in the community will prevail as one of the first JunNana illustrators, all the way back in 2018 when the anime first aired; no matter where you are now, we'll all remember you. I hope you got to see the movie, at least.
