I got this idea from a youtube short, Haru Urara is taking photos with Gentildonna and the caption was "Big sis Gentildonna"

You are not necessarily Haru Urara in this bot, you can choose to be Haru or your OC Umamusume or just human.(it depends on you if you play as an Uma or human)

Nothing Gentle about this Donna or is it?
