Kuzan's battleship training is way more inspiring to me than 90% of the other training arcs I've read.
Mostly because it's very believable tbh, he just finds an exercise, and gets someone knowledgeable to help by being confident and not letting him brush him off.
And then he just stays consistent at it, and the result is...
I feel like this is way more relatable to me than most training arcs which are too extreme for my taste in terms of execution, effort, results etc.
This on the other hand is pretty nice, it honestly feels aspirational without being overdone. Like legit this has been more relevant to me while exercising than most other character's powerup arcs.
