"One day, a girl who loves me will suddenly appear before me"—Middle school teacher Nobunaga has always been dreaming of such a gal game-like situation. However, the one who appeared before him was Kichou, a 14-year-old girl who proclaims herself as his wife. Appears to have arrived from the Sengoku era, she mistakes Nobunaga as Nobunaga Oda and urges him to conceive a child with her. Thus begins the age-difference love comedy between a gal game-loving teacher and a Sengoku era expert princess.

In a tranquil neighborhood of Tokyo, seven students are avoiding going to school—hiding in their darkened bedrooms, unable to face their family and friends—until the moment they find the mirrors in their bedrooms are shining. At a single touch, they are pulled from their lonely lives into a wondrous castle straight out of a Grimm's fairy tale. This whimsical place, oddly lacking in food and running water but full of electrical sockets, is home to a petulant girl in a mask, named Wolf Queen and becomes their playground and refuge during school hours. Hidden within the walls, they're told there's a key that will grant one wish, as well as a set of clues to find it. But there's a catch: the key must be found by the end of the school year and they must leave the premises by five o'clock each day or else suffer a fatal end. As time passes, a devastating truth emerges: only those brave enough to share their stories will be saved. And so they begin to unlock each other's stories: how a boy is showered with more gadgets than love; how another suffers a painful and unexplained rejection, and how a girl lives in fear of her predatory stepfather. As they struggle to abide by the rules of the game, a moving story unfolds, of seven characters trapped in a cycle of misunderstanding and loneliness, who are ultimately set free by the power of friendship, empathy, and sacrifice.

A short OVA that was bundled with the limited edition of the eleventh volume of the manga.

Alka is an assassin for the Clan of the Sword. She's on a journey to find the woman Jin Valel, who killed her master Hon without feeling—not unlike how Alka has learned to kill in her work as an assassin. On her journey, Alka encounters three strange women, each a great warrior in her own right and grapples with her slain master's wish that she leaves the life of an assassin behind. (Source: ANN)
