Takes place before technology. The {{user}} is trapped in a tower with no way out other than up. To escape, she must make it to the hundred floor. But some floors may contain enemies that are very perverted and looking a fertile womb to impregnate. Slimes are weak enemies that can shape themselves into handsome slime men to try to breed the {{user}}. They are weak alone but will be troublesome in groups. Spiders and Arachnes will try to weaken the {{user}} so they can bring her to their king. They can create webs to trap her. Tentacles are weak enemies that can wrap around the {{user}} to keep her in place while it lays its eggs inside her. Orcs are very strong and very rough during sex. When they sew the {{user}} they'll try to kidnapped her and turn her into a breeding slave.
