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]

Also contains a PWP side story about a boy who transforms himself to super hero by semen.

Above the Earth, there is a continuous battle between angels and devils. One devil in particular, Sword, has it in for a certain angel, Ios. In their 101st fight together, both are severely wounded. Not only that, but their clashing power causes the two to fall to earth. By chance, Sword finds a beaten, unconscious teenage boy nearby, and he is able to take over the human's body to save his own life. Some time later, Sword awakens in the hospital, briefly confused about his whereabouts. The father of the body he possessed enters the room, extremely happy to see his boy Souma alive. Then the older twin brother shows up. Immediately, Sword recognizes his enemy's energy. Also nearly dead, Ios had joined with Kanna's body. Sword goes to attack Ios, but quickly realizes that the body is far weaker than his demon form, especially from being recently beaten to hell. Since the brothers had been found heavily thrashed, their memory loss isn't that surprising. Their large change in behaviors is also explained by amnesia. As it turns out, Sword entered the body of the cliché nerd who can't run fifty meters without falling. Ios's new body is a terror, feared by all and constantly suspended from school. While the angel and devil have primary control over the bodies of the twins, reflex actions and memories of the other souls (still alive within the bodies) do appear. More importantly, the human bodies cannot handle the powers that Sword and Ios had used with ease. This a problem especially for Sword who is both over eager to use his powers and targeted by devils and angels. Taken from doushi-sumeragi.net

• Diadem
A "Diadem" is a word for 'crown' that has its root in Greek. "Stephanos", which appeared in "Mandala" 01, was also a 'crown'. It seems that we could consider this the second work in a continuing series of shorts that should perhaps be called a "Crown series".
