Slightly Damned is affiliated with Hiveworks, and such, has a product section on Hivemill! You can find lots of prints here!
Supporting Chu on Patreon is a great way to support the comic! Patrons can submit suggestions for and download exclusive wallpapers, see WIP art and doodles, and get access to private streams every week. Commission announcements are made here as well.
A Kickstarter campaign to fun the printing of Slightly Damned: Book Two (and perhaps Book Three) is planned for early 2020.
Thanks for your support! Please stay tuned!
