Shikanosuke Yamanaka: the Road to Niko's Resurrection

Looking for Japanese Warring States Novels

I recently played Taige Encyclopedia and Oda Noboru, and found that Japan's Warring States Period is quite interesting. Do you have any novel recommendations? Thank you. It seems that only some old books from many years ago have the category "Uesugi Sister". New books can no longer be found in this type.
