A paper I wrote trying to figure out why Umamusume works as well as it does considering the premise is literally just horse girls. It really does work though, and a big part of that is how much care goes into each character's individual arc.
I looked at how the episodic structure keeps stakes high without feeling repetitive, how the relationships between characters carry as much weight as the actual races, and how the game quietly redefines what "winning" means over time. Ended up being one of the more interesting things I've written for class.
