A excerpt from "Tezuka's Ancestor Dr. Ryoan"

"The new era is approaching. It's just around the corner. Ride on the tide of the Pacific!"

This is a longer story depicting the lives of young people struggling through the political turbulence of the transition from the Edo to Meiji periods.
Manjiro Ibuya, a young samurai, becomes a student of a kendo (Japanese fencing) school of Chiba Shusaku, a master of kendo. On his third day at the school, however, Chiba dies. Trouble at Chiba's wake leads Manjiro to a duel with a senior pupil, Kiyokawa Hachiro.
The injured Manjiro is treated by Ryoan, son of Tezuka Ryosen, a doctor practicing western medicine imported from Holland in the same Koishikawa neighborhood. This event brought the two together.
While Manjiro is determined to live the vanishing way of life of the samurai, Ryoan is just as determined to clear the way for modern medicine, fighting against ignorance and superstition.
Choosing totally opposite ways of life and looking upon each other as rivals, the two adore the same woman, and both lived passionately through this stormy age.
