hmm, if you acctually need opposition that could worry the Trinity how about;
for millenea (or any other large factor of time) things have been sealed away instead of properly dealing with them. Demons, evel mind controling rune weapons, the dark kingdom, things more xenocidal than the Covenant. All of them where locked away behind the great seal.
Now that seal is weakening and the Trinity is trying to get a champion ready to stop them, but the more they aid and perpare him the faster the seal cracks. Now things are starting to slip through the cracks, and the trinity has it's hands full making sure things can only slip out near their champion.
This allows you to have a trully varied set of oponnets, and even spectacular battles as these things clash with each other.
E: "Did they... did they just endorse the combination of the JSDF and US Army by showing them as two lesbian lolicons moving in together and holding hands and talking about how 'intimate' they were?"
B: "Have you forgotten so soon? They're phasing out Don't Ask, Don't Tell."
