I'm sorry... I don't know the answer to some of that. But I'll do my best to explain.
[ He shakes his head softly. Exactly as quiet and calm as Toki is agitated and loud. This is how he's dealt with negative feelings (and aren't they all, now?) for such a long time he struggles with other ways. Just... be worn out by them. ]
Spirits are vulnerable to outside influences and it's difficult for them to stay in our world under their own power unless they're especially strong.
[ All true, as far as he knows. The spirits he's encountered have all drawn power from some external force to keep themselves on Earth. ]
Something I have not encountered before has some sort of ability to manipulate spirits- your sister was not the only victim of it. It creates a mask and drives them to act to harm those they loved in life.
[ He holds up his hands, palms up. A grey, smokey sphere forms between them and as he moves his hands apart, it separates into two- one black and one white. That might illustrate what he didn't do, but he's not saying it's what he did. So where's the lie? ]
