10th Anniversary Game: Guess The Drama? - Round 13 (UPDATED with last hint)

Seems like the previous round was pretty tough? Here is the answer for Round 12:

Gou ~ Himetachi no Sengoku 江 ~ 姫たちの戦国

This 2011 NHK Taiga featured Ueno Juri as the lead Gou who was the youngest sister Azai Nagamasa. Her elder sisters were played Miyazawa Rie and Mizukawa Asami thus explaining the first hint of "three sisters". Perhaps there were not many players who had watched this Taiga since they are usually close to 50 episodes long and last for the whole year? The sound clip which I posted as the question was taken from the opening theme which I thought sounded quite soft in contrast to the usual "manly" style of most Taiga theme music but clearly, it wasn't as distinctive as I assumed.

Here is the leaderboard at the end of this round (players with at least 20 points):

56 points - Nanda Motta
55 points - tweetpersecond
50 points - Vie Chan
46 points - Madoka
44 points - mikilove13
