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.
