is there going to be some post story stuff? Or more stuff about them when they get out of the PC?
Nothing more, aside from missing lewd art. Those are Endings after all for a reason. Sequels aren't planned as I have other projects that need my attention. I feel like this is a good way to end it too.
Does this mean there will never be a continuation? It really depends if demand for Gomamon Trainer is big enough to come back a few years down the line. For now I would assume that this is it.
