It was either that, or let her destroy friend and foe alike, along with her family and herself. And considering how practical Saiga is, he might've gone ahead and done it, regardless of how much it tore his heart out to do so. I really hope the same fate doesn't befall Miu, I really do. That would be a sucky end to the manga.

Wait, what!?
The way I remember it is Miu's Father, in other words Saiga Furinji, fell to not his ki but his way of thinking changed and he became a Satsujin fighter. Miu's mother tried to stop him but was killed.
Where did it say Miu's mother fell to her Dou Ki?
