Yeah, that's probably why he didn't use a +100 level Hadô. ;)

Perhaps the most powerful Kidô requires multiple Shinigami performing syncronized incantations to be cast? That could be one of the duties of the Kidô Corps; they are a very secretive unit after all.

If Ittô Kasô, is called the "spell of sacrifice", then a beefed-up version of that spell would be "spell of a dozen sacrifices". (Now that Hadô would land at about level 125, wouldn't you say?) ^^
