Sengoku Rance is the tenth release of the Rance series launched by Alicesoft. The story takes place during the 4th sengoku (warring states) era of JAPAN, an area of the Rance World which parodies medieval real-world Japan.

Sengoku Rance picks up where Rance 6 left off. Rance, after saving the nation of Zeth from destruction, ran away so he won't have to marry the princess. He and Sill ended up in JAPAN for a hotspring trip, upsetting the power balance of JAPAN, and sets the unification of its provinces in motion. Meanwhile, an ancient evil power stirs from its slumber...

The actual story of this manga follows the daughter of one of the feudal lord defeated by Rance. She is the last guardian of the three sacred treasure rumored to end the conflict in JAPAN and is now protected by Uesugi Kenshin.

Tensei Colosseum: Saijaku Skill de Saikyou no Onna-tachi wo Kouryaku Shite Dorei Harem Tsukurimasu

Also known as Reincarnation Coliseum: The Weakest Skill Conquers the Strongest Women and Creates a Harem.

Status: Releasing
Genres: Action , Ecchi , Fantasy

The story begins when high school boy Mikagami, whose only redeeming feature is his skills in video games, is summoned to a different world. He has only the weakest skill "Copy" and, for being useless, he is turned into a sword-fighting slave in the coliseum. Mikagami is pale in the face of the coliseum, where the worst punishment is that "the loser becomes the winner's slave and is mated". The story depicts how he uses his weakest skill "Copy" with the confidence that he has never lost in a "game" before, and how he manages to defeat the stronger players in a duel as if it were a game.
