I just caught up and watched Bleach Thousand-Year Blood War Episode 37 for the first time, and Nanao and Shunsui both delivered in Cour 3 of TYBW. Nanao and Shunsui are working together to take down Lille Barro, one of the Sternritters in Cour 3 of TYBW. I can confidently say that the Bleach anime did a great job at adapting Nanao and her Zanpakuto. Episode 37 of Bleach TYBW proved to be one of the best animated episodes in Bleach as well as being one of the best written as shown by Nanao. This Bleach summary covers episode 37 of TYBW and summarizes the anime. I can say regardless if you watched the Bleach anime or read the manga, Cour 3 and TYBW are PEAK!!
