For the upcoming Comiket in May, I’m planning to focus on Assassin. That said, I haven’t given up on my goal to draw the Sorcerer and Solomon (Goetia) at least sometime within this year. I’ll do my best to bring as much stock as my circle space and production budget allow.
As for the C97 venue-exclusive bonus booklet—I originally intended to turn those into a series with different themes. I figured as long as they had a minor “I guess I’ll check this out since Furumi drew it” kind of appeal, that would be enough. However, if there’s more demand for them than I anticipated, I’d like to make them available via mail order starting next time.
The trouble is, I can’t quite predict the “sweet spot” for the print run—the right amount to reach everyone who wants one without bankrupting myself in the process—so nothing is decided yet. There’s a chance I might end up sticking to venue-exclusive copies again.
