Questions about the silky acrobat yokai

1: Yes, she was able to pass on because Aira basically pretended to be her daughter (while also obviously talking about her own mother).

2:

3: Because that's just how Turbo Granny is. Blunt and to the point. Even if she deep down cares.

Turbo Granny doesn't know her story, only Momo and Aira knows what happend to her. The other questions are not important, Aira forgave her and helped her while she was passing, so it doesn't matter what happend to her daughter, what's important is the link between she and Aira

1. she was able to pass on, without regrets.

2. we dont know what happened to the daughter. in the manga this is the panel . You can interpret that as if both have died and now both of them pass on.

3. Thats just how turbo granny is, like last episode she said she wasnt going to help them and as soon as they were eaten she demanded acro silky to returned them.
