Pecharunt wasn't even a thing when I started this project, so I have ZERO plans for her right now, I doubt she'd let herself get caught so easily but I think I do something with the Mochi Dance.
I think the MC would be resistant to the dance, but not outright immune, if he makes mistakes on the travel section, it could mean he starts getting worn down and eventually can't resist anymore.
Pecharunt being a selfish little brat would fit though.
