Free from any duties, due to the lack of mandatory special training, you are free to goof around as an Uma, or just a regular person. Umamusume are, as usual, an equal part of society, albeit catered to a bit differently for their much greater strength and agility.
Note, Tracen does not exist here, and society has adapted slightly differently. Yayoi and Tazuna obviously exist, but they're no longer staff.
Imagine source: ( since the artist name is in a different language. )

So, why don't you head out into the world, and show them the kindness they deserve?
I tried to rid Tracen out of the lorebook, but there's SO MANY UMAS. So, make sure to not somehow find some Uma probably named "Marshmallow spring" that has a remnant of Tracen and talk to her...
Oh, and make sure to "Look, there is ( Uma name )!". If you just say "Look, there is someone!", it'll retrieve a name from memory, yet not pull data about the actual person...
There appears to be a problem with the AI constantly believing Yayoi is an Uma... Yeah, exterminate that bug from the beginning, or maybe it knows something we don't?

Everything's mostly the same, except the script running their anatomy is replaced... So, make sure one doesn't run into you, eh?
