Also known as: Yuki Yuna is a Hero: The Washio Sumi Chapter; WaSuYu; 結城友奈は勇者である -鷲尾須美の章-
Summary: Three elementary school students are to become heroes and protect Shinju-sama, the god tree that protects humanity, from the mysterious Vertex. These 6 episodes also serve as a prequel to Yuki Yuna wa Yusha de Aru.
Due to how it’s written, WaSuYu could possibly be watched before YuYuYu (which is the original series) and the viewer wouldn’t be missing all that much, probably. YuYuYu heavily really depends on the impact of certain plot twists and WaSuYu revisits such scenes. That means watching WaSuYu first would probably spoil the fun, as it were.
Look. I think you can either watch WaSuYu first or YuYuYu first. WaSuYu only hints at the developments and the reveals which gets fleshed out in YuYuYu. YuYuYu also provides the backstory and history and explains whereas WaSuYu assmes you’ve already watched YuYuYu and skips such details. You do you and choose since both can work. Both are somewhat similar in themes, visuals, and narrative scope, however, so you should probably steer away from WaSuYu if you weren’t a fan of YuYuYu. With that being said, the presentation of WaSuYu is quite different, for better or for worst, which affects how the viewer perceives WaSuYu.
