Ummm so she will made Nobunaga's dream come true, that's uniting the whole japan... And then probably japan would become much crueller than our current history... because Japan is lead by Nobunaga lineage..(which is a very cruel, idealistic, realistic, and open minded person)... It's just my theory..but I do hope if she change Japan entire history I hope it won't become like Japan in our history (which is cruel in the 19th and early to mid 20th century) if they still invade other nations it's alright they have reason for that but I hope it won't be as much cruel as before..
