Has black cat been shown on adult swim or will it be?
No, unfortunately it has never aired on Adult Swim and honestly, I doubt it ever will. They are very particular on which shows to air although I agree with you it does seem like the type of show that they would air. Adult Swim just doesn’t air as much anime as they used too, it’s all on Saturdays now and that is the only day they ever show anime. Plus Black Cat has been out for a while now and if they haven’t aired it now, they probably never will. However, I don’t see why they shouldn’t air it, it is an awesome show if I do say so myself, ^_^!
