Ikemen Sengoku: The Three Sisters

Azuna and her two sisters, Karou and Nanami, used to have normal lives in the modern world. A few years ago when Azuna was 17, both of her parents died in an accident and she had to become a mother to her younger siblings. After their parents died, Azuna had to get stronger and worked a day and night job to support her sisters who were still in school. One day, she and her sisters took a holiday in Kyoto to take a break and then the three sisters met Sasuke, a university student who studies wormholes as a hobby.

Suddenly, Sasuke and the three sisters were sent back 500 years into the past, where Nobunaga was supposed to have died on that very same year. What will happen when the three sisters meet the warlords of the Sengoku period? will they be able to go home back to the modern world when the next wormhole appears or will the three of them fall in love with one of the warlords?
