The germ of the idea came from knowing that, in OTL, Osamu Tezuka (father of the mukokuseki character design*), studied to be a doctor. Wikipedia provided more details and even an exact Jonbar hinge:
'When he was younger, Tezuka's arms swelled up and he became ill. He was treated and cured by a doctor, which made him want to be a doctor. However, he began his career as a manga artist while a university student, drawing his first professional work while at school. At a crossing point, he asked his mother whether he should look into doing manga full-time or whether he should become a doctor. At the time, being a manga author was not a particularly rewarding job. The answer his mother gave was: "You should work doing the thing you like most of all." Tezuka decided to devote himself to manga creation on a full-time basis. He graduated from Osaka University and obtained his medical degree, but he would later use his medical and scientific knowledge to enrich his sci-fi manga, such as Black Jack.'
Maybe the Warriors' World Tezuka took the other choice and became a kindly doctor who occasionally drew educational manga. The prospect... I won't say appeals to me, but it interests me strangely.
