Okay, I'm failing to see how this is "world ending." She releases her magic unconsciously, but it's damn difficult to see that being, I dunno, a "magical nuke" or something. Even the biggest releases of magic energy have been localized things. And, if half-demon/half-humans were THIS dangerous as to be considered "world ending" and even making angels piss themselves... Why the fuck haven't the demons been breeding half breeds to basically make magical nuke equivalents or even just supersoldiers to fight the angels? Yeah, yeah, I get it. Yomina is a rare/special case because yaddayadda. That still doesn't explain why the demons wouldn't TRY if half-breeds COULD be this dangerous.
I mean, I don't want to think about this too much, but part of the manga's sub-plot is about Yomina = dangerous and even her former childhood friends potentially killing her and... Hino for some god damn reason. So it's unfortunately made into a bit of an important issue when it didn't need to be one.
I ain't complaining, however, since I always liked this series and hoped someone would pick it up again, so seeing anything continued is nice. And thanks to WaveRSX for that.
