Lmao no they weren't. Both VNs are straight up kusoge that were only worth reading for the light references in Muramasa. There's a reason Jin was put on the backlines for the following Nitroplus projects he was a part of and has been stuck doing anime tie-ins since. I'm surprised they even let him do a Demonbane sequel, though that ended up being the straw that broke the camel's back. Now look at him now: working on an anime adaption of a chink mobage with a hack who directed two anime adaptions so bad that people pretend they don't exist. Yikes.
