Description:

On his first day of high school at the formerly all-girl's Ousai Private Academy, Takatoshi Tsuda is called out for his untidy uniform by the student council president Shino Amakusa. In apology for delaying Takatoshi for his first class—and stating that the group needs a male point of view to accommodate the arrival of boys at the school—Shino offers him the position of vice president of the student council. Though unwilling, Takatoshi finds himself appointed as the newest member of the student council having yet to even step foot inside the school building. Takatoshi soon realizes that the other student council members who are more than a little strange: President Shino, who is studious and serious in appearance, but actually a huge pervert, fascinated with the erotic and constantly making lewd jokes; the secretary Aria Shichijou, who may seem like a typical sheltered rich girl, but is just as risque as the president, if not more so; and finally, the treasurer Suzu Hagimura, who may act fairly normal, but has the body of an elementary school student and is extremely self-conscious of it. Surrounded by these colorful characters, the new vice president must now work through a nonstop assault of sexual humor and insanity. [Written by MAL Rewrite]

Monster Musume: Everyday Life with Monster Girls

7.13

Description:

With his parents abroad, Kimihito Kurusu lived a quiet, unremarkable life alone until monster girls came crowding in! This alternate reality presents cutting-edge Japan, the first country to promote the integration of non-human species into society. After the incompetence of interspecies exchange coordinator Agent Smith leaves Kimihito as the homestay caretaker of a Lamia named Miia, the newly-minted "Darling" quickly attracts girls of various breeds, resulting in an ever-growing harem flush with eroticism and attraction. Unfortunately for him and the ladies, sexual interactions between species is forbidden by the Interspecies Exchange Act! The only loophole is through an experimental marriage provision. Kimihito's life becomes fraught with an abundance of creature-specific caveats and sensitive interspecies law as the passionate, affectionate, and lusty women hound his every move, seeking his romantic and sexual affections. With new species often appearing and events materializing out of thin air, where Kimihito and his harem go is anyone's guess! [Written by MAL Rewrite]

No Game, No Life

8.23

Description:

No Game No Life is a surreal comedy that follows Sora and Shiro, shut-in NEET siblings and the online gamer duo behind the legendary username "Kuuhaku." They view the real world as just another lousy game; however, a strange e-mail challenging them to a chess match changes everything—the brother and sister are plunged into an otherworldly realm where they meet Tet, the God of Games. The mysterious god welcomes Sora and Shiro to Disboard, a world where all forms of conflict—from petty squabbles to the fate of whole countries—are settled not through war, but by way of high-stake games. This system works thanks to a fundamental rule wherein each party must wager something they deem to be of equal value to the other party's wager. In this strange land where the very idea of humanity is reduced to child’s play, the indifferent genius gamer duo of Sora and Shiro have finally found a real reason to keep playing games: to unite the sixteen races of Disboard, defeat Tet, and become the gods of this new, gaming-is-everything world.
