China, early Song Dynasty.

The setting is an era of absolute corruption, when bribery, torture, and threats were the normal way of doing business in the government. Then comes forth a young, new Official - Houjou - who challenges the corruption. Gifted by the Emperor with three beheading devices, he is charged with bringing justice back to the courts.

Based on the historical figure of Justice Bao (Chinese reading of the name), who was said to be an incorruptible official, this is a light-hearted romp through ancient China as he and his assistants work against the corruption that has become the norm in the Imperial Courts.

This can be considered as sequel of Proclaiming and Loving with the Lu Kou's young brother.
The story begins during the Sung Dynasty of ancient China. The country is in great chaos due to the infamous Jin Kang Rebellion. Fearing the possible destruction that is sure to ensue, Concubine Liu tearfully entrusts the care of her baby daughter, Princess Yi Fu, to a common citizen named Tang Hui. Tang Hui immediately escapes with the princess to the south. And so, Princess Yi Fu's whereabouts become a mystery.
Now, ten years later, the Tang have returned to power and the great family wishes for all exiled family members to return. But Zi Li is happy with her life.

Date Bashira is a series of stories about the Sengoku era in Japan. However, unlike most textbooks and historical mangas, Date Bashira does not focus on the Shogun or famous figures in history. Instead, it brings to light the untold stories of the things surrounding these famous figures. For example, one story tells about the role of how beautiful young men were always accompanying the shoguns into battle. As women were not allowed into a battle zone, the warlords would use these teenage boys to satisfy their sexual urges.

A different chapter tells the history of the wives of the Shoguns and focuses on the female role in the Sengoku era. As young women were forced into arranged marriages, usually as peace offerings or spies, their husbands usually die in battle at a very early age, as it was the era of war. Date Bashira discusses the idea of remarriage for these women and if they were really in love or were playing the role of a wife.

Date Bashira takes a different perspective at one of Japan’s most talked about era and even though it is informative, you never get the feeling of a lecture. The beautiful artwork, splash of comedy and the untold, yet interesting historical information really keeps the reader glued onto the pages. [vyc, mangahelpers]
