(Don't Worry or I'm sorry), there's no way she's going to stay that way long enough to get to +9.
I was originally just going to go directly to Catalina's turn, but I wanted to get Ashley suggesting this in a comic somewhere, and this seemed a good spot for it.
For the record, this isn't a reflection of Ashley wanting to permanently change herself in any way. She's really into a lot of different, and potentially extreme, transformation scenarios in fictional / safe / roleplay environments, but at the end of the day, she wants to return to default. She's happy with her normal form.
As for Hanma's reaction, it's sort of similar to my own? I mean, definitely no to this, but at the same time, a form that has progressively better / worse pros and cons is a genuinely interesting idea for this game. It should probably just, y'know, be shrinking based or something.
