>"That's not what I asked of you, Champion of Water. You say that questioning our nature as those who kneel is a weakness. Why is it so?"
Alright, going to cut the questioning short. Or at least this round of questioning. I would like to put forth a permutation on our previous suggestion: I think the best way to open its mind a little is to make it experience powerlessness. I believe, given its beaten state, that we may be able to put a proper seal on it, based off of Karmic Touch, that will short-circuit any magic it tries. On top of this, we may be able to set it up to give it a good paralyzin' zat if it tries to enact violence against another being or meet with a demon. If possible, maybe, maybe set this curse up to rob it of physical power as well, to fuel these other effects.
Now, if we made this now and forever, it wouldn't be very useful, nor would it do much to really drive any lessons home. And it would just make us seem a bit cruel in its eyes. So, it would need a release clause. That clause would be: When Kiku and it's other victim forgives it.
The hopeful result would be: It's reasonably free to live, but at the same time, it can't really do anything harmful. And, it would have to move toward reconciliation if it ever wanted to get back to its prime state again; I don't think it's really equipped to trick Kiku AND the other victim into it. The important part of this being it'd not be able to just ignore Terran society, and would have to make at least some effort to fit in, especially if it wants to regain its power. In short, we make it have to learn. And we'd have access to it if needs be.
