I thought terufuu had died or something, his last upload was more than half a year ago. Christ, I'm not even concerned about the pic right now, it's just good to know that the person is ok.
Now, as for the pic, another fucking masterpiece if I say so myself. Saved~~!
Just because someone doesn't make a post for an extremely long time doesn't mean they died or anything, it just means that they are taking a bit of a break and probably trying to find some inspiration and ideas for new artworks.
