it's too early to tell, we need to see what happens when a human wins:
1. will the valkyrie survive? if the valkyrie dies even if the human wins, then chances are this series will have a dark/bittersweet ending.
2. will the god permanently die?
3. what kind of effect will the first human victory have on the other gods (i.e. will they finally start respecting humanity, or even fearing humanity?)
There is also the issue that if humans win 7 matches, they would supposedly only get humans only another 1000 years, and then gods will decide again whether to destroy humanity, so I think Hild will form a contingency plan so the gods aren't able to make that decision again: and I'm betting the human victors will be involved in the contingency plan.
