As someone who’s been making custom cards, this has my attention.
How would y'all feel about knowing your Digimon for a few years prior to the rp.
Like an egg was found in your home and you being a good person allowed it to hatch and bonded with the Digimon
This way it's a little less suspension of belief for the strong bond being there. As well as being able to have established behaviors relations and etc with the Digimon to begin with.
Or would y'all prefer to meet your Digimon for the first time in the rp itself and write through and that development. Let me know.
