This is STARGAZER’s debut title. Katana had a dream one day: he was the ultimate ruler on a giant battleship floating in space, meeting his loyal and admiring subjects. This moment of unspeakable bliss was shattered by a sharp pain in his chest. He saw blood when he put his hand to his chest and wondered if he was going to die. Even though he knew it was a dream, he felt extreme loss and sadness as he fell… into the arms of a naked girl. She told him that even though this was just a dream, it could happen at a later time and that she would protect him. Katana woke up confused and found the same naked girl in front of him. She introduced herself as EXE, a war maiden called ‘slavenil’, sent to protect him… or at least get his genes if she failed to do so. Four other girls later appeared, also after his life or genes. They were the space pirate Yuraha, the princess of a fallen kingdom Tsukino, the assassin Nao, and another slavenil EXA. In the middle of the fierce fight among them, it happened that they all moved in with him. What will happen to Kanata and these five girls?
