The protagonist is Tsugikuni Michikatsu. A word of warning before reading: this may be quite heartbreaking. Every scene serves as a key setup for what comes later, so there is no filler. It contains a great deal of invented historical detail and extensive original speculation. The romance is very subtle, so read with care. The story is divided into three parts: the Warring States period, the Edo period, and the Taisho period. Tsugikuni Michikatsu is not purely good- 48Reads—Score—Shelves
