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!
