Daiakuji

Nihon lost the war, women now run everything, and Yamamoto Akuji comes home from a POW camp to find his family empire handed to his grandfather's old mistress. His own men beat him half to death for the trouble.

Left for dead and picked up by a neighborhood patrol squad, Akuji does the only thing that makes sense to him: he turns on the people holding him and bends their leader to his will. From there it's a slow climb back to the top of Osaka, one broken loyalty at a time, with the new female-run order as the obstacle standing between him and his birthright.

The game runs on turn-based combat wrapped around management and strategy layers, so building up territory, resources, and a growing harem of subordinates matters as much as winning fights. Akuji's rise is built through leverage, coercion, and control rather than charm, and the game doesn't pretend otherwise.
