Uncensored: https://thunderhub.itch.io/gahamama
Happily, Kaminarimon is back and stable online with most (but not all) of the old sets situated on different shopfronts. A big exception though seems to be the Thunderhub library. A good amount of which (mainly newer) can be found on:
https://thunderhub.itch.io/
But the older sets that seemingly didn't have uncensored data backed up aren't being put up there, and after three weeks, they sadly don't seem to be going up anywhere. I'll pirate what I've got from that saved tonight, plus the remaining Thunderhub sets on hand.
Kaminarimon is still active right now on Patreon (uncensored) and Pictspace/Booth (censored). I won't start pirating anything from there for a little while, but I hope anyone who likes this work will consider contributing some support.
