Welcome to Japoness! While surveying the planet Terra II, the seeding ship, Mesopotamia, ran into difficulties. The seeding pod was launched; however, the ship destructed before the crew could escape. Only six men survived. 300 years later, Terra II flouishes but is an all-male society (achieved through advanced cloning, they were able to create variations although the rulers are pure clones). Marionettes have taken the place of females; these are mechanoids devoid of feelings and carry out most of the tasks. Otaru Mamiya often wishes he could afford one but he likes life just the way it is. One day, he has had enough of his "best" friend, Hanagata, haggling him and thus decides to fight him and his gang. Just when he was getting the upper hand, he makes a mistake and falls into the river. Upon his recovery, he finds himself at the abandoned Japoness museum where he accidently finds a marionette; however, Lime is not like any he has ever seen or heard. With the impending attack of Gartlant against Japoness, Otaru finds himself in the middle of a love triangle with other marionettes, Cherry and Bloodberry.
