Original title: 武将娘と子作り生活 ～凛々しく可憐な戦国美少女があなたの子種を巡ってエロイチャ孕み合戦！～
Our story begins with Jun, and his childhood friend Yui, cleaning the dean's office as punishment for Yui's latest prank. Of course, if nothing went wrong this would be a pretty bland story which leads to Yui knocking over a pretty old and expensive looking vase and from it emerge two Sengoku Era generals but... they're hot babes?! The ever-reliable Yui bolts as soon as the vase shatters leaving our protagonist, Jun, responsible for helping Uesugi Kenshin and Takeda Shingen adapt to modern Japan. Experience a wild ride alongside Jun and the commander babes as they unravel the secrets of modern mathematics, the English language, and the art of babymaking!
