1) Youma show up conveniently where the heroines are.
In a real attack, as the attacker, I'd want to y'know, hit fast, hit hard *away* from the Magical Bigs that could smack me around then disappear. No need for huge energy gatherings -- a small to decent size here, another small to decent size there...
2) Youma show up one at a time.
You've already broken that stereotype with the soldier aspect.
3) There is only *one* Youma attack at any given time.
Doesn't make sense to me. Sacrifice a few causing rampage in a metropolitan area and hit elsewhere.
4) Everything happens in Japan.
Hit elsewhere... as in Europe or America. Or China.
5) Youma show up consistently and steadily increasing but managable power levels.
Till the Magical Bigs build up to challenge Evil Magical Big. Yeah. Or not -- have it be erratic. One week they get hit with a couple hundred attacks then the next two months it's nothing before an incredible power jump (supposedly spending the last two months building up). And vary the times -- early morning, late at night, lunch time... Predictable is Not Good and keeping the TSAB on high alert/stressed at all times will lead to mistakes during battles.
