Oops, double post. And yes, you were right about tone. I mean, there can be minor jokes, just don't expect lots of silly situations that are allowed to last long. Awkward situation humor and sarcasm are more welcome, but I will let someone be silly if they feel they need to cheer someone up with it. Just don't expect an attempt to fight a Demon Lord with a cream pie fight to get very far. Also expect the result of a human attempting to punch a Digimon to be a broken wrist at least. Not a threat, just a statement of Digimon are strong and the majority of threatening ones won't mess around.
